Look at cut or awk or sed either of those would do it for you.

Hey there,

If you want to do these en masse, you can either cd to the directory, or use a full path name and then apply that code generically to all the files in a for loop, while loop or using xargs, etc. That way your filename would be $x (or whatever you want to call your iterative variable) and not specifically the name of one file.

Hope that helps

, Mike
