Hello all. I need to rename a number of directories (in the range of 1000) and all of the mp3 files included in this directories (over 20000). What I want to achieve is to replace all of the dashes with underline sign. Some time ago I found a script to rename files this way within a given directory which looks as follows: for i in *.mp3; do mv "$i" `echo $i | tr "-" "_"`; done This script works very well within a given directory but doesn't want to work from the top directory witch actually includes this nearly 1000 subdirectories. As an example, I'm getting somthing like this: mv: cannot move `./Kolakowski-Leszek-Klucz-niebieski/01-klucz-niebieski.mp3' to `./Kolakowski_Leszek_Klucz_niebieski/01_klucz_niebieski.mp3': no such file or directory It was suggested to me to replace *.mp3 with `find . -name '*.mp3'` But unfortunately, it did not work. I'm not a programmer just a user who tries to be smart, so, please be patient and treat me like a newbie. :-) hope all of you on here have a great new year. Thanks, Pawel.
