Interestingly, the double quotes inside double quotes seems to work on my machine (using /usr/local/bin/bash), perhaps because the contents inside the "$( )" are processed in a subshell? Output of terminal session follows: ~/tmp/test> touch 'filename with spaces.bak' 'file two.bak' file3.txt file4.BAK ~/tmp/test> ls -l total 0 -rw-r--r-- 1 xscd xscd 0 Oct 23 11:45 file two.bak -rw-r--r-- 1 xscd xscd 0 Oct 23 11:45 file3.txt -rw-r--r-- 1 xscd xscd 0 Oct 23 11:45 file4.BAK -rw-r--r-- 1 xscd xscd 0 Oct 23 11:45 filename with spaces.bak ~/tmp/test> ~/tmp/test> echo "$(find . -xdev -type f -iname "*.bak" | sed "s/\(^.*$\)/'\1'/")" './filename with spaces.bak' './file two.bak' './file4.BAK' ~/tmp/test> Now because of your response I am motivated to read and learn more about find's -print0 option and about xargs.
