Revert all modified files in an SVN repo

This command allows you to revert every modified file one-by-one in a while loop, but also after "echo $file;" you can do any sort of processing you might want to add before the revert happens.

Know a better way?

If you can do better, submit your command here.

What others think

...or instead of hacking things up with pipes and stuff you could simply use git:

git checkout -f master

Why do people forget that awk has it's own regex filtering capabilities? Anytime you see grep, awk, sed, perl, cut (and a few others) piping into each other, then it's likely able to be improved. In this case:

svn st | awk '/^M/ {print $2}' | xargs svn revert

I think both of your comments are nice, but we're not forgetting - we're just showing options here on cmdlnfu.

Comment by wsams 47 weeks and 4 days ago

Older versions of awk had some annoying limitations which may explain the habit of reaching for grep, cut, sed first.

According to 'The AWK Programming Language'

the limits of AWK are:

100 fields

3000 characters per input record

1024 characters per field

15 open files

1 pipe

won't "svn revert -R" work?

Comment by unixmonkey37567 44 weeks and 3 days ago

Oh that's pretty cool, sometimes I want to do work on all newly added files. Like add a license statement to the top and commit each, but not the entire working copy.

svn status | grep "^A" | while read entry; do file=`echo $entry | awk '{print $2}'`; echo $file; sed -i '1i MY LICENSE AUTHOR 2012' $file; svn commit $file -m "Adding $file"; done
