Hi,
I understood that @ARGV is used to hold the command
line parameters given to a perl script. But, when I
tried to access them, its empty.
The following code piece assumes two command line
options be given, the first one being the -f switch
and the second one being the file name itself.
myscript.pl -f test.txt
So, $0 will be myscript.pl and I want to really test
whether the user specifed all the arguments and the
arguments are correct.
So, I've to check
if($#ARGV < 2)
{
print $USAGE;
}
BTW, what is this $USAGE. I saw it in some books and
just copied here. Please let me know how to use
$USAGE also.
The following is the pseudo code I want to use by
using @ARGV.
if($ARGV[0] !~ /-f/) print "Wrong switch";
if($ARGV[1]) !~ //) print "Empty file name not
allowed";
But, since @ARGV is empty, I am unable to validate the
command line arguments.
Please throw me some ideas on how to access the
command line arguments and what's going wrong here.
PS: I am using Perl5.6.1.exe on Win 98.
Thanks in advance,
Sudarsan
