I am new to PERL and I think this should be a simple one... I want to convert this script to PERL:

grep -s $x /etc/security/user
if [[ $? = 1 ]]
then
SANS="No"
else
SANS="Yes"
fi

So can I start with something like this:

if (-e "/etc/security/user"){
    print "Yes \n";
    } else {
    print "No \n";
    }

But in fact Your code does little more

$ok = 0;
$x = "pattern to match";
$file = "etc/security/user";
if (open(F, $f))
{
 while(<F>)
 {
  if (/$x/)
  {
    $ok = 1;
    last;
  }
 }
 close(F);
}
print ($ok ? "Yes\n" : "No\n");

$x="searchPattern";
open F, '</etc/security/user' or die "Can't open the file:$!";
if ( grep/$x/, <F> ) {
print "Yes";
}
else {
print "No";
}
close(F);
