Hi all,
Am wanting to change my Perl scripts to get it to run on several UNIX
flavours and Windows. At the moment, the only way I can think of how to
accomplish that is always having the following checks on each and every
sub
that I have.
Can anyone please suggest if there is a better way of doing this besides
what am doing now? Am not sure whether creating a module for each OS to
use
is the solution although I don't know how to create a module anyway. I
found
one tutorial and get lost somewhere along the way on how to create a
module
... :-)
if ($^O eq 'MSWin32') {
system "dir $ARGV[0]";
}
...
Whenever it is possible it is recommended to use core functions or Perl
modules instead of external programs and commands.
If you want to read the list of files from a directory you can use
opendir(), readdir(), closedir() or glob().
Read the POD documentation for those functions using:
perldoc -f opendir
perldoc -f glob
...
