What Others Think

Lets see... 1. Using basename would be better than using sed here. 2. Use of unquoted variables means you will have problems if the files contain embedded whitespace This version addresses those issues (and is shorter as well): for i in *.bak ; do nuname=`basename "$i" .bak`; echo renaming "$i" to "$nuname";mv "$i" "$nuname"; done
