This is expected because on the UNIX shell the asterisk ("*") gets
wildcard-expanded into a list of files in the current directory and the are
added to @ARGV one by one. See
https://en.wikipedia.org/wiki/Glob_%28programming%29 . What you probably want
is:
my ($archive, @list_of_files) = @ARGV;
See:
http://altreus.blogspot.com.au/2011/08/lists-and-things-made-of-lists.html
One other note is that doing something like "tar -cavf myarc.tar.gz *" is not
advisable because: 1. If myarc.tar.gz already exists in the directory it may be
clobbered. and - 2. It is to mistake with "tar -cavf *" which will clobber the
first file it finds (and it happened to a co-student of mine at the Technion
who had to redo most of his work).
I try to always do "tar -cavf myarc.tar.gz mydir/". If you're looking for a
packaging interface, see patool:
