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' _ {} +

Alternatives

There is 1 alternative - vote for the best!

Terminal - Alternatives

Would this command line achieve the desired function? My CLI knowledge is not great so this could certainly be wrong. It is merely a suggestion for more experienced uses to critique. Best wishes roly :-)

ls * | sed -e 'p;s/foo/bar/' | xargs -n2 mv

Renames all files in a directory named foo to bar.

foobar1 gets renamed to barbar1

barfoo2 gets renamed to barbar2

fooobarfoo gets renamed to barobarfoo

NOTE: Will break for files with spaces AND new lines AND for an empty expansion of the glob '*'

rename foo bar filename
for f in *; do mv "$f" "${f/foo/bar}"; done

without sed, but has no problems with files with spaces or other critical characters

ls | sed 'p;s/foo/bar/' | xargs -n2 mv

What others think

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

Comment by eightmillion 212 weeks ago

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.

Comment by RanyAlbeg 212 weeks ago

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?

Comment by windfold 211 weeks ago

Acutally, I take it back this command is better:
