Script needed; git mavens can you help?

Hi git mavens,

I've used a script called svnrevert in the svn version that reverts any changed file in its argument(s), which may be directories, /and/ sets the modification date to the date at which the file was last checked in. I'd like the same functionality in git. Her'es the subversion version:

#!/bin/bash

# Revert file(s) or all modified files in a directory

# and touch them back to the checkin date

for f in "$@"

if [ -d "$f" ]; then

$0 `svn st "$f" | grep "^M" | sed 's/^M *//'`

else

if svn revert "$f"; then

changed="`svn info \"$f\" | grep 'Last Changed Date:' | sed 's/ *(.*//'`"

touch -t "`date -j -f 'Last Changed Date: %Y-%m-%d %H:%M:%S %z' \"$changed\" '+%Y%m%d%H%M.%S'`" "$f"

done

_,,,^..^,,,_

best, Eliot

without the modification-date requirement

git checkout -- ....

does what you want (given you have NOT staged/git-added it before).
I'm curious, what's important about the last commit date?

Best regards

To complete Tobias's answer, git checkout HEAD -- <files> will restore files from the most recent commit even if changes were staged.

In what situation do you use that script?

People on stack overflow seem to have pretty polarized opinions about fiddling with timestamps… one of the answers has something close, but there might be a simpler way…

Hi Eliot,

When I did the migration I made a gitrevert script. It is in the scripts dir.

Best,
Tim

Thanks Tim. Just an FYI for Mac users, the script presumes an up-to-date git, but Mac OS X yosemite only ships with 2.4.9. The upgrade is easy; I'm currently using 2.10.0.

Best,
Tim

Then apple unecessarily exposes its users to vulnerabilities, so they are urged to upgrade.
