Re: Batch file rename question (consecutive file numbers)

This is EXACTLY what I was looking for - thank you very much for your
help. I just piped to bash, and all of my files were renamed
accordingly. I did have to be in sh (instead of bash), and

export n=''

before executing the command, after multiple uses. VERY COOL!!!!

Problem:
I need to rename a batch of files:
foo_001.jpg
foo_002.jpg
foo_003.jpg
bar_001.jpg
bar_002.jpg
bar_003.jpg
....and so on.
I need to take the number on these files (notice how the number is
duplicated on foo and bar) and make the entire batch consecutive. In
other words, I want the file list to look like this:
foo_001.jpg
foo_002.jpg
foo_003.jpg
bar_004.jpg
bar_005.jpg
bar_006.jpg
....and so on.
I'd appreciate any ideas! I just feel like this is so simple and I'm
just not seeing the answer!

$ ls
foo_001.jpg
foo_002.jpg
foo_003.jpg
bar_001.jpg
bar_002.jpg
bar_003.jpg
$ n=0; for i in *; do n=$((n+1)); nn=`printf "%03d" $n`;
echo mv $i ${i/_*\./_$nn.}; done
mv foo_001.jpg foo_001.jpg
mv foo_002.jpg foo_002.jpg
mv foo_003.jpg foo_003.jpg
mv bar_001.jpg bar_004.jpg
mv bar_002.jpg bar_005.jpg
mv bar_003.jpg bar_006.jpg

Seems like what you want.

p.

PS Always test first with "echo mv" before actual "mv". Could be good
idea to use "mv -i", just in case.
