Git cheatsheetEdit
Pushing matching refs
git push origin :
Retrieving a file from a specific revision
git show <treeish>:filename
git push origin :
git show <treeish>:filename
For example, if you delete a file in a particular revision, say 3ad8389, and only later discover that you should have kept it, you can get it back with:
git show 3ad8389~1:filename > filename
(ie. show the file as it was in the revision before 3ad8389, where it got deleted.)
Equivalent in this case is:
git checkout 3ad8389~1 -- filename
This just writes the file back out to the working tree without touching the HEAD.
Negative pathspecs
:! (or :^) (source).
Example; examining a diff that contains a bunch of copies and renames as well as abundant changes to "package-lock.json" files:
git diff develop -C10 -M20 -b --find-copies-harder -- ':!*-lock.json'`
