I'm trying to check if a user exists in /etc/passwd on a remote
Here is my code, tried to do this 2 different ways, neither way will work.
Any advice ?
@pairs = split(/&/, $buffer);
foreach $pair (@pairs) {
($name, $value) = split(/=/, $pair);
$value =~ tr/+/ /;
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
$FORM{$name} = $value;
}
$userid = $FORM{userid};
$username = $FORM{username};
#chomp ($userid);
print $userid;
@listusers = `ssh -i ~/.ssh/whoisit <ipaddress> -l <userid> 'cat
/etc/passwd'`;
print "<p>";
foreach $file (@listusers) {
print "$file";
# if ($userid =~ /a.*/) {
if ( $userid =~ /^$file./ ) {
print "exists";
## yes, it matches
} else {
print " not exist";
# print " does not exist";
## no, it doesn't
}
print "<br>";
}
print "<p>";
foreach ($i = 0; $i<$#listusers; $i++) {
# if ($userid =~ /^$listusers[$i]/) {
# if $listusers[$i] =~ /a/) {
print "$listusers[$i]";
print "<br>";
if ( $userid =~ /^$listusers[$i]/i ) {
print "exists ";
## yes, it matches
} else {
print " does not exist ";
## no, it doesn't
}
}
