Rename all files which contain the sub-string 'foo', replacing it with 'bar'

for i in ./*foo*;do mv -- "$i" "${i//foo/bar}";done
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 : Recursive version: find . -depth -name "*foo*" -exec bash -c 'for f; do base=${f##*/}; mv -- "$f" "${f%/*}/${base//foo/bar}"; done' _ {} +

What Others Think

Just because a command has problems doesn't mean it's not clever.

I can see what you mean, but I disagree. Your clever is, by my terms, useless complexity. In fact, a properly constructed command is less complex. ls,sed and xargs does not indicate about anything but a waste of resources which is also dangerous.

Hey If you're going to hate why don't you put the hate where it belongs: In the comments of my command instead of marring the beauty of your command?
