|
36 | 36 | |
|
37 | 37 | Delete files not known to mercurial, this is useful to test local and |
|
38 | 38 | uncommitted changes in the otherwise clean source tree. |
|
39 | 39 | |
|
40 | 40 | This means that purge will delete: |
|
41 | 41 | - Unknown files: files marked with "?" by "hg status" |
|
42 | 42 | - Ignored files: files usually ignored by Mercurial because they match |
|
43 | 43 | a pattern in a ".hgignore" file |
|
44 | 44 | - Empty directories: in fact Mercurial ignores directories unless they |
|
45 | 45 | contain files under source control managment |
|
46 | 46 | But it will leave untouched: |
|
47 | 47 | - Unmodified tracked files |
|
48 | 48 | - Modified tracked files |
|
49 | 49 | - New files added to the repository (with "hg add") |
|
50 | 50 | |
|
51 | 51 | If directories are given on the command line, only files in these |
|
52 | 52 | directories are considered. |
|
53 | 53 | |
|
54 | 54 | Be careful with purge, you could irreversibly delete some files you |
|
55 | 55 | forgot to add to the repository. If you only want to print the list of |
|
56 | 56 | files that this program would delete use the --print option. |
