It seems safer and more consistent to use "." as the example dir instead of "/tmp/".

@CpnCrunch, as the answer says, the utility is sometimes named prename. I found "prename" using Yum and it works as advertised. Now, writing a portable script, that is a whole different matter...

you cannot use rename on macOS unless you explicitly install it

| Sep 4, 2017 at 10:39 | comment | added | Mohamed El-Nakeep | On OS X, first do this: stackoverflow.com/a/15003450/2008463 $brew install findutils rename $ alias find=gfind | |

rename seems to be the most incompatible script (fedora don't work, custom ubuntu half does) - could someone please include a list of working rename versions....

@CpnCrunch Same in RHEL 6.2 and Cygwin (rename --version says rename from util-linux 2.x.x, but a good tool for mass renaming anyway

| Nov 4, 2015 at 20:07 | comment | added | Dennis Williamson | @CpnCrunch: The Perl script is very short and various versions are available on CPAN and elsewhere. | |
| Nov 4, 2015 at 3:03 | comment | added | CpnCrunch | This doesn't work on Centos 7, as the rename command is completely different (it's a binary, not a perl script), and it doesn't accept data from stdin. | |

@FredConcklin: In GNU find . (the current directory) is the default search root.

|
| Mar 7, 2015 at 17:31 | comment | added | user284244 | You forgot to specify . in the find command so there is no directory root to search. | |

@PhysicalChemist: You have single quotes inside your alias. Try alias space_to_under='find . -depth -name "* *" -execdir rename "s/ /_/g" "{}" \;' or alias space_to_under='find . -depth -name "* *" -execdir rename '\''s/ /_/g'\'' "{}" \;'

Sure. Bash Profile Alias: alias space_to_under='find . -depth -name "* *" -execdir rename 's/ /_/g' "{}" \;' and the Terminal Output after sourcing -bash: alias: /_/g "{}" \;: not found

Note that the command has a trailing ; issue when aliased in a bash profile. But it is totally fine in a bash profile function.

If you're running this on OS X, you'll need to brew install rename

| Apr 26, 2010 at 18:33 | comment | added | Michael Krelin - hacker | Of course you're not going to get a performance boost from it. It's more about using the right tool. And this whole question is about micro-optimizing more or less. Isn't it fun, after all? ;-) | |
| Apr 26, 2010 at 15:51 | comment | added | Dennis Williamson |
Micro-optimization. In my tests there was negligible difference in speed. time for i in {1..2000}; do echo "a b c d [repeated to a length of 320 characters]" | perl -pe 'y/ abcdefghi/_ABCDEFGHI/' >/dev/null; done compared to 's/ /_/g; s/a/A/g; s/b/B/g; s/c/C/g; s/d/D/g; s/e/E/g; s/f/F/g; s/g/G/g; s/h/H/g; s/i/I/g'. Of course, the transliteration command has its advantages, but so does the substitute command.

Oh, I've just read the rename manpage (I didn't know the tool) and I think you can optimize your code by changing s/ /_/g to y/ /_/ ;-)

added another version

| Apr 25, 2010 at 20:53 | comment | added | Michael Krelin - hacker | hmm.. Dennis, what would happen if you have "a a", "a a/b b" directories? Wouldn't it try to rename "a a" to "a_a" and then "a a/b b" (which doesn't exist anymore) to "a_a/b_b"? | |
