Re: how to rename multiple files
There are also mmv, mcp, mad, and mln. The syntax takes a little
getting used to, but once you get a feel for it, this is a nice set of
programs. I think you can apt-get mmv.
Here's an example I used yesterday. It takes a bunch of files
starting with week, then a 0 or a 1, then a single character, followed
by .gpg.out and moves them to a bunch of files named "week, first
match, second match, .cport.
mmv "week?.gpg.out" "week#1#2.cport"
So, for example the file called week01.gpg.out is renamed
week01.cport. The #1 matches the first wildcard in the from pattern,
here the ''. The #2 matches the single character wildcard.
One very nice thing about mmv, etc. is that if an error is detected
(for example, multiple files go to a destination with the same name),
the program doesn't do anything and tell you. There is also a dryrun
flag for testing that things are going as you wish. The man page is
quite detailed. Give it a chance and read it a couple times.
