Rename all files which contain the sub-string 'foo', replacing it with 'bar'
That is an alternative to command 8368. Command 8368 is EXTREMELY NOT clever. 1) Will break also for files with spaces AND new lines in them AND for an empty expansion of the glob '*' 2) For making such a simple task it uses two pipes, thus forking. 3) xargs(1) is dangerous (broken) when processing filenames that are not NUL-terminated. 4) ls shows you a representation of files. They are NOT file names (for simple names, they mostly happen to be equivalent). Do NOT try to parse it. Why? see this :http://mywiki.wooledge.org/ParsingLs Recursive version: $ find . -depth -name "*foo*" -exec bash -c 'for f; do base=${f##*/}; mv -- "$f" "${f%/*}/${base//foo/bar}"; done' _ {} +
