I have some 1600 files where the first 7 characters of each file name is in
the format "CN NNN ". I would like to be able to change these via a program
to the format "CN-NNN-". The files are actually hymns and these 7 characters
are followed by the first line of the hymn.
Can anyone out there help, or do I have to go through manually making the
changes? I would appreciate any valid comments.
I use a sed & mv script I call 'rename' for things like this, but it
works on Cygwin or other Unix-like systems. With it, I'd do this:
rename 's:\(..\) \(...\) :\1-\2-:' C*
.... but this may be impractical for you.
