How to locate and recover a deleted file

Question

At some stage in the past I had a "foo.txt" which was under Mercurial source control. However it has now been deleted.

How can I recover the file when I don't know the last Mercurial revision in which the file was deleted?

Answer 1

If you know the exact path for the file, you can do something like :

hg log -l 1 path/to/foo.txt 

This will show you the last changeset where foo.txt was modified, so you will be able to restore the file from this revision.

Once you have the right revision, you can simply do :

hg revert -r <my revision> path/to/foo.txt hg commit -m "add the foo.txt file again" 

Answer 2

Using revsets:

hg log -r "removes('path_to_file')" 

Where path_to_file can be anything documented in hg help patterns, including an exact path, a glob or a regular expression.
