perl, how to know if a command execution is asking password?

I need to execute a command through perl script, if it asks for password to execute i need to ignore otherwise i can proceed further.

my $cmd = `ssh root\@192.168.1.1 '/bin/cat /root/a.txt'`;

Besides using something like Net::SSH::Perl like I suggested above. You can enable batchmode

my $cmd = `ssh -oBatchMode=yes root\@192.168.1.1 '/bin/cat /root/a.txt'`;

if batchmode is set to yes, it will disable the querying of password/passphrase, which makes it pretty useful in scripts
