Using sed to create a directory

[kellnerp]

That thread was closed without an answer. Here is the key to what he was trying to do, not the whole solution.

I have a file: 12345-6789A.prt
I would like to create a directory: 12345-6789+A/

If I have 50 similarily named files (#####-####X.prt) I would like to create 50 directories.

I think I can use sed, for example:

for file in *;
do mkdir `echo $file | sed 's/'$1'/'$2'/g'` ;
done

where $1 is "12345-6789" and $2 is "12345-6789+", but I don't know how to make $1 and $2 be what I want.

Can someone help?

Thanks,
Jeff

Maybe this would help:

ls -X *.jpg | sed -r s/"^(.+)(\.jpg)"/"\1\/&"/

ls was used to get some meaningful input and sed's output was dumped to stdout just for testing. The idea for the regex came from Vladimir.

The rename command might do what the OP wanted more simply.
