Replace square brackets to underscore in all filenames (current dir.)

perl -e 'map { $on=$_; s/\]/_/; rename($on, $_) or warn $!; } <*>;'

What Others Think

command is wrong in at least one respect. The regex only includes the right bracket, and only the first occurrence therein. The rest of the brackets would remain. This could have been redone with a little more elegance (at least in part) with: perl -e 'map +{ ($on,$nn)=($_,$_); $nn =~ s/\[\]/_/go; rename($on, $nn) or warn $! } <*>' I could see more people doing it without perl tho. Such as: for file in $(echo *|grep -E '(\[|\])'); do mv $file $(echo $file|sed -r 's/(\[|\])/_/g'); done While I think the second is more ugly, it's shell script and more attuned to what folks around here are used to seeing.

Use the rename script that comes with perl, called prename. Sometimes it is also symlinked from rename. See 'man prename' for more. You could likely write your command like this: prename 'y/[]/_/' * my regex may be off though.
