118 | |
119 Delete files not known to mercurial, this is useful to test local and | |
120 uncommitted changes in the otherwise clean source tree. | |
121 | |
122 This means that purge will delete: | |
123 - Unknown files: files marked with "?" by "hg status" | |
124 - Ignored files: files usually ignored by Mercurial because they match | |
125 a pattern in a ".hgignore" file | |
126 - Empty directories: in fact Mercurial ignores directories unless they | |
127 contain files under source control managment | |
128 But it will leave untouched: | |
129 - Unmodified tracked files | |
130 - Modified tracked files | |
131 - New files added to the repository (with "hg add") | |
132 | |
133 If directories are given on the command line, only files in these | |
134 directories are considered. | |
135 | |
136 Be careful with purge, you could irreversibly delete some files you | |
137 forgot to add to the repository. If you only want to print the list of | |
138 files that this program would delete use the --print option. | |
