PHP Scripting to convert underscores to spaces
Greetings,

I have a bunch of music files that I want to strip the underscores out, and leave only spaces. All that I've found on the web is how to add underscores to files that have spaces, and reversing the "tr" command does not make a difference.

Here is how to convert spaces to underscores:

Code:
#!/bin/sh

ls | while read -r FILE
do
    mv "$FILE" `echo $FILE | tr ' ' '_' `
done

I am able to strip the underscores by typing:
Code:
ls | while read -r FILE
do
    mv "$FILE" `echo $FILE | tr -d '_'`
done

This gets rid of the underscores, but then there are no spaces in the filename (ex. 01_foo becomes 01foo).

The command to change underscores to spaces still eludes me.

Can you help me, or point me in the right direction...

Regards,
Bryan
