  • This command can be used to revert a particular changeset in the local copy. I find this useful because I frequently import files into the wrong directory. After the import it says "Committed revision 123" or similar. to revert this change in the working copy do: svn merge -c -123 . (don't forget the .) and then commit. Show Sample Output


    1
    svn merge -c -REV

  • Works recusivley in the specified dir or '.' if none given. Repeatedly calls 'find' to find a newer file, when no newer files exist you have the newest. In this case 'newest' means most recently modified. To find the most recently created change -newer to -cnewer. Show Sample Output


    1
    newest () { DIR=${1:-'.'}; CANDIDATE=`find $DIR -type f|head -n1`; while [[ ! -z $CANDIDATE ]]; do BEST=$CANDIDATE; CANDIDATE=`find $DIR -newer "$BEST" -type f|head -n1`; done; echo "$BEST"; }
