Editing filenames in a directory 1

[Zugdud]

Howdy folks, is there a way to rename a directory full of files? i just need to remove the - out of the filename and chage the first letter (always a T) from upper case to lower case, so for example I want T-234 to be t234

This is on a redhat 9 linux system, thanks!

mv T-234 t234

Well, sorry should have been more specific. Is there a command that will do groups of files at a time? Theres several thousand files to rename

A starting point:
ls T* | while read f
do mv $f $(echo $f | sed 's!^T!t!;s!-!!g')
done

Hope This Helps, PH.

You don't mention what platform you're on, but many unices come with a 'rename' command that takes wild cards and patterns. Otherwise you'll have to script it like PHV suggests.

Cool hey, just tried it out and the system does indeed have the rename command. Just from fooling around with it alittle, it does seem pretty user friendly so even I can handle using it.

Thanks for the headsup!

In Awk:
[tt]
awk 'BEGIN {
for (i=1;i<ARGC;i++)
{ $0=ARGV
sub(/^T/,"t"); gsub(/-/,"")
cmd="mv " ARGV " " $0
system( cmd )
}
exit
}' T*
