Comparison of command line argument in perl
Hello All,

I have passed one command line argument in my script.
I want to compare that value in the script itself.
Is there any way to compare the command line variable.......

are you meaning this ?

Code:
$ cat t.pl 
if ( $ARGV[0] == 10 )  {
print "yes it is 10";
}

Code:
$ perl t.pl 10
yes it is 10

Yes you can pass a string.
Use the string comparison operator eq in that case.

Code:
$
$ cat t.pl
#!perl -w
if ($ARGV[0] eq "xyz") {print "Yes it is xyz\n"}
else {print "No it is not xyz\n"}
$
$ ./t.pl xyz
Yes it is xyz
$
$ ./t.pl abc
No it is not xyz
$
$
