Thanks to all who have spent precisous time looking at my code.
Perhaps let me clarify a few things
1. I am working on Windows with cygwin (and perl) installed. When I did which cat I got the path and indded cat is there.
2. I write the date to file because when I use it I get 2009414 (for example istead of 20090414). That part of the code works.
3. The files are meteorological reports (synop, temp, metar, etc) which keep coming as they are produced so one cannot guess the exact named of the report, except that it is msgnnnnnnnn where nnn... is an 8-digit number.
4. The idea of the program is to put all report for a day in one file and them they are processed by other programs.
Thanks
Zilore

However, if your command shell is the default for win32, it will not
like you expressing a path like that (it treats '/' as a switch prefix,
not a directory separator). What do you get when you try to run cat from
the default win32 command prompt like that? Try cat without the explicit
path. If it works for mv it should work for cat.

It is the printf part that does the formatting that you want. If you use
sprintf instead you don't need to write a file. See 'perldoc -f
sprintf'.

Your code seemed to have some logic errors. I believe I pointed out a
couple of them.
