Hi Tytalus,
thank you for the quick response but it doesn't seem so work. (I might be doing something wrong, since I'm just starting to try this kind of stuff)
The filename has been renamed, but it takes the first line in the file.
Therefore I attached the actual ps file.
What I forgot to mention is that the filename itself is also variable, so I was wondering whether your solution would work as well with the *.ps in stead of the file.ps?
If my file looks like this….
10
20
30
and I want to take each line individually and put it in a variable so it can be read
later in it's on individual test statement, how can I do that? I guess what I'm asking is how can I extract each line individually.
Thanks (5 Replies)

rename - renames multiple files
SYNOPSIS
rename [ -v ] [ -n ] [ -f ] perlexpr [ files ]
DESCRIPTION
"rename" renames the filenames supplied according to the rule specified as the first argument. The perlexpr argument is a Perl expression
which is expected to modify the $_ string in Perl for at least some of the filenames specified. If a given filename is not modified by the
expression, it will not be renamed. If no filenames are given on the command line, filenames will be read via standard input.
For example, to rename all files matching "*.bak" to strip the extension, you might say
rename 's/.bak$//' *.bak
To translate uppercase names to lower, you'd use
rename 'y/A-Z/a-z/' *
OPTIONS -v, --verbose
Verbose: print names of files successfully renamed.
-n, --no-act
No Action: show what files would have been renamed.
-f, --force
Force: overwrite existing files.
ENVIRONMENT
No environment variables are used.

If you give an invalid Perl expression you'll get a syntax error.
BUGS
The original "rename" did not check for the existence of target filenames, so had to be used with care. I hope I've fixed that (Robin
Barker).
