I am using the following Perl script to determine the last logon of all users in /etc/passwd. I am VERY new to Perl, and I need to limit the search, however, to users that have a similar word (string) in their home directory. I am more POSIX shell savvy, but this is what I kinda am looking for: grep (string) /etc/passwd Using this file, is there somewhere I could grep for this (string) instead of sourcing in the entire /etc/passwd file? 
#!/usr/local/bin/perl
# Show last logins for every user in /etc/passwd
#
open(LASTLOGIN,"last|") || die "Cannot run 'last' command\n";
while (<LASTLOGIN>) {
next if $_ eq "";
if (/^wtmp begin/) {$begin=$_ ; next};
($name,$tty,$date)=/(\S+)\s+(\S+)\s+(\S+\s+\S+\s+\S+)/;
$user{$name}=$date unless $user{$name};
}
print $begin;
close(LASTLOGIN);
open(PASSWD,"/etc/passwd") || die "Cannot open '/etc/passwd'\n";
while (<PASSWD>) {
next if /^\+/;
($name,$rest)=split(":");
$user{$name}="**No Logon Since /etc/wtmp File Created**" unless $user{
+$name};
}
foreach $name (sort keys(%user)) {
printf "%-10s %s\n",$name,$user{$name};
}
