I don't claim this as the best way to do the job, but it was an interesting hour or so of bash learning for me.

Try this:

#!/bin/bash

prev_ext='ZZZZZZZZZZZZZ'

# "ls -X" sorts directory in alphabetical order by extension # This makes it easy to know when to create a new directory.

for f in `ls -X` do filename=$f # extract the extension # if no extension, the full filename is returned this_ext=${f##*.} echo $f $this_ext if [ $f != $this_ext ] then if [ $prev_ext != $this_ext ] then prev_ext=$this_ext mkdir $this_ext fi mv $filename $this_ext fi done

I've trouble making bash script to move files from a directory to a new directory--(named as the files' extension name). For example: moving files *.pdf on /foo/ to /foo/pdf/, but there are so many extension. But how ? Thx in advance.
