I would do this like this:
$ git log --pretty=%H HEAD~9..HEAD | (i=0; while read h; do \ git show $h:PATHNAME >/tmp/file~$i; i=$((i+1)); done) With the real (relative) pathname of the file substituted for PATHNAME. This will create a bunch of files "file~0", "file~1" etc under /tmp, each representing the state of the file PATHNAME in the HEAD, one commit before HEAD etc. Note that this takes exactly 10 adjacent commits no matter whether the file of interest changed in any of them (or even present in any of them); if, instead, you need to see a series of 10 commits in which the file was changed, you have to supply PATHNAME to the git-log as well, like this: $ git log --pretty=%H HEAD~9..HEAD PATHNAME | ... Note that in this case the trick with using a counter to name destination files might not have much sense and you will want to play with `git name-rev` for instance. -- You received this message because you are subscribed to the Google Groups "Git for human beings" group.
