#!/usr/bin/perl
print "which client\n";
$a = <>;
$db = <>;
$dir="/u1/data/$a";
$avar="$dir/$db;
print "$avar";
When you use something like:
$a = <>;
you are getting the contents of $a from the command line and it will include a
newline at the end so when you see:
which client
and you type:
cold1man
your perl program assigns the string "cold1man\n" to the variable $a. You
need to chomp the variables first before you can use them:
#!/usr/bin/perl
use warnings;
use strict;
print "which client\n";
my $a = <>;
chomp $a;
my $db = <>;
chomp $db;
my $dir="/u1/data/$a";
my $avar="$dir/$db;
print "$avar";
