git-annex has a powerful syntax for making it act on only certain files.
|
|
|
|
The simplest thing is to exclude some files, using wild cards:
|
|
|
|
git annex get --exclude '*.mp3' --exclude '*.ogg'
|
|
|
|
But you can also exclude files that git-annex's [[location_tracking]]
|
|
information indicates are present in a given repository. For example,
|
|
if you want to populate newarchive with files, but not those already
|
|
on oldarchive, you could do it like this:
|
|
|
|
git annex copy --not --in oldarchive --to newarchive
|
|
|
|
Without the --not, --in makes it act on files that *are* in the specified
|
|
repository. So, to remove files that are on oldarchive:
|
|
|
|
git annex drop --in oldarchive
|
|
|
|
Or maybe you're curious which files have a lot of copies, and then
|
|
also want to know which files have only one copy:
|
|
|
|
git annex find --copies 7
|
|
git annex find --not --copies 2
|
|
|
|
The above are the simple examples of specifying what files git-annex
|
|
should act on. But you can specify anything you can dream up by combining
|
|
the things above, with --and --or -( and -). Those last two strange-looking
|
|
options are parentheses, for grouping other options. You will probably
|
|
have to escape them from your shell.
|
|
|
|
Here are the mp3 files that are in either of two repositories, but have
|
|
less than 3 copies:
|
|
|
|
git annex find --not --exclude '*.mp3' --and \
|
|
-\( --in usbdrive --or --in archive -\) --and \
|
|
--not --copies 3
