HG(1) ===== Matt Mackall <mpm@selenic.com> NAME ---- hg - Mercurial source code management system SYNOPSIS -------- 'hg' [-v -d -q -y] <command> [command options] [files] DESCRIPTION ----------- The hg(1) command provides a command line interface to the Mercurial system. OPTIONS ------- -R, --repository:: repository root directory --cwd:: change working directory -y, --noninteractive:: do not prompt, assume 'yes' for any required answers -q, --quiet:: suppress output -v, --verbose:: enable additional output --debug:: enable debugging output --traceback:: print traceback on exception --time:: time how long the command takes --profile:: print command execution profile --version:: output version information and exit -h, --help:: display help and exit COMMAND ELEMENTS ---------------- files ...:: indicates one or more filename or relative path filenames; see "FILE NAME PATTERNS" for information on pattern matching path:: indicates a path on the local machine revision:: indicates a changeset which can be specified as a changeset revision number, a tag, or a unique substring of the changeset hash value repository path:: either the pathname of a local repository or the URI of a remote repository. There are two available URI protocols, http:// which is fast and the old-http:// protocol which is much slower but does not require a special server on the web host. COMMANDS -------- add [options] [files ...]:: Schedule files to be version controlled and added to the repository. The files will be added to the repository at the next commit. If no names are given, add all files in the current directory and its subdirectories. addremove [options] [files ...]:: Add all new files and remove all missing files from the repository. New files are ignored if they match any of the patterns in .hgignore. As with add, these changes take effect at the next commit. annotate [-r <rev> -u -n -c] [files ...]:: List changes in files, showing the revision id responsible for each line This command is useful to discover who did a change or when a change took place. Without the -a option, annotate will avoid processing files it detects as binary. With -a, annotate will generate an annotation anyway, probably with undesirable results. options: -a, --text treat all files as text -I, --include <pat> include names matching the given patterns -X, --exclude <pat> exclude names matching the given patterns -r, --revision <rev> annotate the specified revision -u, --user list the author -c, --changeset list the changeset -n, --number list the revision number (default) bundle <file> <other>:: (EXPERIMENTAL) Generate a compressed changegroup file collecting all changesets not found in the other repository. This file can then be transferred using conventional means and applied to another repository with the unbundle command. This is useful when native push and pull are not available or when exporting an entire repository is undesirable. The standard file extension is ".hg". Unlike import/export, this exactly preserves all changeset contents including permissions, rename data, and revision history. cat [options] <file ...>:: Print the specified files as they were at the given revision. If no revision is given then the tip is used. Output may be to a file, in which case the name of the file is given using a format string. The formatting rules are the same as for the export command, with the following additions: %s basename of file being printed %d dirname of file being printed, or '.' if in repo root %p root-relative path name of file being printed options: -I, --include <pat> include names matching the given patterns -X, --exclude <pat> exclude names matching the given patterns -o, --output <filespec> print output to file with formatted name -r, --rev <rev> print the given revision clone [options] <source> [dest]:: Create a copy of an existing repository in a new directory. If no destination directory name is specified, it defaults to the basename of the source. The location of the source is added to the new repository's .hg/hgrc file, as the default to be used for future pulls. For efficiency, hardlinks are used for cloning whenever the source and destination are on the same filesystem. Some filesystems, such as AFS, implement hardlinking incorrectly, but do not report errors. In these cases, use the --pull option to avoid hardlinking. options: -U, --noupdate do not update the new working directory --pull use pull protocol to copy metadata -e, --ssh specify ssh command to use --remotecmd specify hg command to run on the remote side commit [options] [files...]:: Commit changes to the given files into the repository. If a list of files is omitted, all changes reported by "hg status" from the root of the repository will be commited. The HGEDITOR or EDITOR environment variables are used to start an editor to add a commit comment. Options: -A, --addremove run addremove during commit -I, --include <pat> include names matching the given patterns -X, --exclude <pat> exclude names matching the given patterns -m, --message <text> use <text> as commit message -l, --logfile <file> read the commit message from <file> -d, --date <datecode> record datecode as commit date -u, --user <user> record user as commiter aliases: ci copy <source ...> <dest>:: Mark dest as having copies of source files. If dest is a directory, copies are put in that directory. If dest is a file, there can only be one source. By default, this command copies the contents of files as they stand in the working directory. If invoked with --after, the operation is recorded, but no copying is performed. This command takes effect in the next commit. NOTE: This command should be treated as experimental. While it should properly record copied files, this information is not yet fully used by merge, nor fully reported by log. Options: -A, --after record a copy that has already occurred -I, --include <pat> include names matching the given patterns -X, --exclude <pat> exclude names matching the given patterns -f, --force forcibly copy over an existing managed file -p, --parents append source path to dest aliases: cp diff [-a] [-r revision] [-r revision] [files ...]:: Show differences between revisions for the specified files. Differences between files are shown using the unified diff format. When two revision arguments are given, then changes are shown between those revisions. If only one revision is specified then that revision is compared to the working directory, and, when no revisions are specified, the working directory files are compared to its parent. Without the -a option, diff will avoid generating diffs of files it detects as binary. With -a, diff will generate a diff anyway, probably with undesirable results. options: -a, --text treat all files as text -I, --include <pat> include names matching the given patterns -X, --exclude <pat> exclude names matching the given patterns export [-o filespec] [revision] ...:: Print the changeset header and diffs for one or more revisions. The information shown in the changeset header is: author, changeset hash, parent and commit comment. Output may be to a file, in which case the name of the file is given using a format string. The formatting rules are as follows: %% literal "%" character %H changeset hash (40 bytes of hexadecimal) %N number of patches being generated %R changeset revision number %b basename of the exporting repository %h short-form changeset hash (12 bytes of hexadecimal) %n zero-padded sequence number, starting at 1 %r zero-padded changeset revision number Without the -a option, export will avoid generating diffs of files it detects as binary. With -a, export will generate a diff anyway, probably with undesirable results. options: -a, --text treat all files as text -o, --output <filespec> print output to file with formatted name forget [options] [files]:: Undo an 'hg add' scheduled for the next commit. options: -I, --include <pat> include names matching the given patterns -X, --exclude <pat> exclude names matching the given patterns grep [options] pattern [files]:: Search revisions of files for a regular expression. This command behaves differently than Unix grep. It only accepts Python/Perl regexps. It searches repository history, not the working directory. It always prints the revision number in which a match appears. By default, grep only prints output for the first revision of a file in which it finds a match. To get it to print every revision that contains a change in match status ("-" for a match that becomes a non-match, or "+" for a non-match that becomes a match), use the --all flag. options: -0, --print0 end fields with NUL -I, --include <pat> include names matching the given patterns -X, --exclude <pat> exclude names matching the given patterns --all print all revisions that match -i, --ignore-case ignore case when matching -l, --files-with-matches print only filenames and revs that match -n, --line-number print matching line numbers -r <rev>, --rev <rev> search in given revision range -u, --user print user who committed change heads:: Show all repository head changesets. Repository "heads" are changesets that don't have children changesets. They are where development generally takes place and are the usual targets for update and merge operations. identify:: Print a short summary of the current state of the repo. This summary identifies the repository state using one or two parent hash identifiers, followed by a "+" if there are uncommitted changes in the working directory, followed by a list of tags for this revision. aliases: id import [-p <n> -b <base> -f] <patches>:: Import a list of patches and commit them individually. If there are outstanding changes in the working directory, import will abort unless given the -f flag. If a patch looks like a mail message (its first line starts with "From " or looks like an RFC822 header), it will not be applied unless the -f option is used. The importer neither parses nor discards mail headers, so use -f only to override the "mailness" safety check, not to import a real mail message. options: -p, --strip <n> directory strip option for patch. This has the same meaning as the corresponding patch option -b <path> base directory to read patches from -f, --force skip check for outstanding uncommitted changes aliases: patch incoming [-p] [source]:: Show new changesets found in the specified repo or the default pull repo. These are the changesets that would be pulled if a pull was requested. Currently only local repositories are supported. options: -p, --patch show patch aliases: in init [dest]:: Initialize a new repository in the given directory. If the given directory does not exist, it is created. If no directory is given, the current directory is used. locate [options] [files]:: Print all files under Mercurial control whose names match the given patterns. This command searches the current directory and its subdirectories. To search an entire repository, move to the root of the repository. If no patterns are given to match, this command prints all file names. If you want to feed the output of this command into the "xargs" command, use the "-0" option to both this command and "xargs". This will avoid the problem of "xargs" treating single filenames that contain white space as multiple filenames. options: -0, --print0 end filenames with NUL, for use with xargs -f, --fullpath print complete paths from the filesystem root -I, --include <pat> include names matching the given patterns -r, --rev <rev> search the repository as it stood at rev -X, --exclude <pat> exclude names matching the given patterns log [-r revision ...] [-p] [files]:: Print the revision history of the specified files or the entire project. By default this command outputs: changeset id and hash, tags, parents, user, date and time, and a summary for each commit. The -v switch adds some more detail, such as changed files, manifest hashes or message signatures. options: -I, --include <pat> include names matching the given patterns -X, --exclude <pat> exclude names matching the given patterns -r, --rev <A> show the specified revision or range -p, --patch show patch aliases: history manifest [revision]:: Print a list of version controlled files for the given revision. The manifest is the list of files being version controlled. If no revision is given then the tip is used. outgoing [-p] [dest]:: Show changesets not found in the specified destination repo or the default push repo. These are the changesets that would be pushed if a push was requested. options: -p, --patch show patch aliases: out parents:: Print the working directory's parent revisions. paths [NAME]:: Show definition of symbolic path name NAME. If no name is given, show definition of available names. Path names are defined in the [paths] section of /etc/mercurial/hgrc and $HOME/.hgrc. If run inside a repository, .hg/hgrc is used, too. pull <repository path>:: Pull changes from a remote repository to a local one. This finds all changes from the repository at the specified path or URL and adds them to the local repository. By default, this does not update the copy of the project in the working directory. Valid URLs are of the form: local/filesystem/path http://[user@]host[:port][/path] https://[user@]host[:port][/path] ssh://[user@]host[:port][/path] SSH requires an accessible shell account on the destination machine and a copy of hg in the remote path. With SSH, paths are relative to the remote user's home directory by default; use two slashes at the start of a path to specify it as relative to the filesystem root. options: -u, --update update the working directory to tip after pull -e, --ssh specify ssh command to use --remotecmd specify hg command to run on the remote side push <destination>:: Push changes from the local repository to the given destination. This is the symmetrical operation for pull. It helps to move changes from the current repository to a different one. If the destination is local this is identical to a pull in that directory from the current one. By default, push will refuse to run if it detects the result would increase the number of remote heads. This generally indicates the the client has forgotten to sync and merge before pushing. Valid URLs are of the form: local/filesystem/path ssh://[user@]host[:port][/path] SSH requires an accessible shell account on the destination machine and a copy of hg in the remote path. options: -f, --force force update -e, --ssh specify ssh command to use --remotecmd specify hg command to run on the remote side rawcommit [-p -d -u -F -m -l]:: Lowlevel commit, for use in helper scripts. This command is not intended to be used by normal users, as it is primarily useful for importing from other SCMs. recover:: Recover from an interrupted commit or pull. This command tries to fix the repository status after an interrupted operation. It should only be necessary when Mercurial suggests it. remove [options] [files ...]:: Schedule the indicated files for removal from the repository. This command schedules the files to be removed at the next commit. This only removes files from the current branch, not from the entire project history. If the files still exist in the working directory, they will be deleted from it. aliases: rm rename <source ...> <dest>:: Mark dest as copies of sources; mark sources for deletion. If dest is a directory, copies are put in that directory. If dest is a file, there can only be one source. By default, this command copies the contents of files as they stand in the working directory. If invoked with --after, the operation is recorded, but no copying is performed. This command takes effect in the next commit. NOTE: This command should be treated as experimental. While it should properly record rename files, this information is not yet fully used by merge, nor fully reported by log. Options: -A, --after record a rename that has already occurred -f, --force forcibly copy over an existing managed file -p, --parents append source path to dest aliases: mv revert [names ...]:: Revert any uncommitted modifications made to the named files or directories. This restores the contents of the affected files to an unmodified state. If a file has been deleted, it is recreated. If the executable mode of a file was changed, it is reset. If a directory is given, all files in that directory and its subdirectories are reverted. If no arguments are given, all files in the current directory and its subdirectories are reverted. options: -r, --rev <rev> revision to revert to -n, --nonrecursive do not recurse into subdirectories root:: Print the root directory of the current repository. serve [options]:: Start a local HTTP repository browser and pull server. By default, the server logs accesses to stdout and errors to stderr. Use the "-A" and "-E" options to log to files. options: -A, --accesslog <file> name of access log file to write to -E, --errorlog <file> name of error log file to write to -a, --address <addr> address to use -p, --port <n> port to use (default: 8000) -n, --name <name> name to show in web pages (default: working dir) -t, --templatedir <path> web templates to use -6, --ipv6 use IPv6 in addition to IPv4 status [options] [files]:: Show changed files in the working directory. If no names are given, all files are shown. Otherwise, only files matching the given names are shown. The codes used to show the status of files are: M = changed A = added R = removed ? = not tracked options: -m, --modified show only modified files -a, --added show only added files -r, --removed show only removed files -u, --unknown show only unknown (not tracked) files -n, --no-status hide status prefix -0, --print0 end filenames with NUL, for use with xargs -I, --include <pat> include names matching the given patterns -X, --exclude <pat> exclude names matching the given patterns tag [-l -m <text> -d <datecode> -u <user>] <name> [revision]:: Name a particular revision using <name>. Tags are used to name particular revisions of the repository and are very useful to compare different revision, to go back to significant earlier versions or to mark branch points as releases, etc. If no revision is given, the tip is used. To facilitate version control, distribution, and merging of tags, they are stored as a file named ".hgtags" which is managed similarly to other project files and can be hand-edited if necessary. options: -l, --local make the tag local -m, --message <text> message for tag commit log entry -d, --date <datecode> datecode for commit -u, --user <user> user for commit Note: Local tags are not version-controlled or distributed and are stored in the .hg/localtags file. If there exists a local tag and a public tag with the same name, local tag is used. tags:: List the repository tags. This lists both regular and local tags. tip:: Show the tip revision. unbundle <file>:: (EXPERIMENTAL) Apply a compressed changegroup file generated by the bundle command. undo:: Undo the last commit or pull transaction. Roll back the last pull or commit transaction on the repository, restoring the project to its earlier state. This command should be used with care. There is only one level of undo and there is no redo. This command is not intended for use on public repositories. Once a change is visible for pull by other users, undoing it locally is ineffective. update [-m -C] [revision]:: Update the working directory to the specified revision. By default, update will refuse to run if doing so would require merging or discarding local changes. With the -m option, a merge will be performed. With the -C option, local changes will be lost. options: -m, --merge allow merging of branches -C, --clean overwrite locally modified files aliases: up checkout co verify:: Verify the integrity of the current repository. This will perform an extensive check of the repository's integrity, validating the hashes and checksums of each entry in the changelog, manifest, and tracked files, as well as the integrity of their crosslinks and indices. FILE NAME PATTERNS ------------------ Mercurial accepts several notations for identifying one or more files at a time. By default, Mercurial treats filenames as shell-style extended glob patterns. Alternate pattern notations must be specified explicitly. To use a plain path name without any pattern matching, start a name with "path:". These path names must match completely, from the root of the current repository. To use an extended glob, start a name with "glob:". Globs are rooted at the current directory; a glob such as "*.c" will match files ending in ".c" in the current directory only. The supported glob syntax extensions are "**" to match any string across path separators, and "{a,b}" to mean "a or b". To use a Perl/Python regular expression, start a name with "re:". Regexp pattern matching is anchored at the root of the repository. Plain examples: path:foo/bar a name bar in a directory named foo in the root of the repository path:path:name a file or directory named "path:name" Glob examples: glob:*.c any name ending in ".c" in the current directory *.c any name ending in ".c" in the current directory **.c any name ending in ".c" in the current directory, or any subdirectory foo/*.c any name ending in ".c" in the directory foo foo/**.c any name ending in ".c" in the directory foo, or any subdirectory Regexp examples: re:.*\.c$ any name ending in ".c", anywhere in the repository SPECIFYING SINGLE REVISIONS --------------------------- Mercurial accepts several notations for identifying individual revisions. A plain integer is treated as a revision number. Negative integers are treated as offsets from the tip, with -1 denoting the tip. A 40-digit hexadecimal string is treated as a unique revision identifier. A hexadecimal string less than 40 characters long is treated as a unique revision identifier, and referred to as a short-form identifier. A short-form identifier is only valid if it is the prefix of one full-length identifier. Any other string is treated as a tag name, which is a symbolic name associated with a revision identifier. Tag names may not contain the ":" character. The reserved name "tip" is a special tag that always identifies the most recent revision. SPECIFYING MULTIPLE REVISIONS ----------------------------- When Mercurial accepts more than one revision, they may be specified individually, or provided as a continuous range, separated by the ":" character. The syntax of range notation is [BEGIN]:[END], where BEGIN and END are revision identifiers. Both BEGIN and END are optional. If BEGIN is not specified, it defaults to revision number 0. If END is not specified, it defaults to the tip. The range ":" thus means "all revisions". If BEGIN is greater than END, revisions are treated in reverse order. A range acts as a closed interval. This means that a range of 3:5 gives 3, 4 and 5. Similarly, a range of 4:2 gives 4, 3, and 2. ENVIRONMENT VARIABLES --------------------- HGEDITOR:: This is the name of the editor to use when committing. Defaults to the value of EDITOR. (deprecated, use .hgrc) HGMERGE:: An executable to use for resolving merge conflicts. The program will be executed with three arguments: local file, remote file, ancestor file. The default program is "hgmerge", which is a shell script provided by Mercurial with some sensible defaults. (deprecated, use .hgrc) HGUSER:: This is the string used for the author of a commit. (deprecated, use .hgrc) EMAIL:: If HGUSER is not set, this will be used as the author for a commit. LOGNAME:: If neither HGUSER nor EMAIL is set, LOGNAME will be used (with '@hostname' appended) as the author value for a commit. EDITOR:: This is the name of the editor used in the hgmerge script. It will be used for commit messages if HGEDITOR isn't set. Defaults to 'vi'. PYTHONPATH:: This is used by Python to find imported modules and may need to be set appropriately if Mercurial is not installed system-wide. FILES ----- .hgignore:: This file contains regular expressions (one per line) that describe file names that should be ignored by hg. .hgtags:: This file contains changeset hash values and text tag names (one of each separated by spaces) that correspond to tagged versions of the repository contents. /etc/mercurial/hgrc, $HOME/.hgrc, .hg/hgrc:: This file contains defaults and configuration. Values in .hg/hgrc override those in $HOME/.hgrc, and these override settings made in the global /etc/mercurial/hgrc configuration. See hgrc(5) for details of the contents and format of these files. BUGS ---- Probably lots, please post them to the mailing list (See Resources below) when you find them.
