Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

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

Terminal - Rename all files which contain the sub-string 'foo', replacing it with 'bar'
rename 's/foo/bar/g' ./*

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

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 :-)


There is 1 alternative - vote for the best!

Terminal - Alternatives
for i in ./*foo*;do mv -- "$i" "${i//foo/bar}";done

Functions: mv

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

User: windfold
Functions: ls sed xargs

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
2011-04-30 09:53:20

Functions: mv

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

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