simple perl script not working
why won't below work?
I am trying to see
a)sipfile has username of the system.
b)it will read the sipfile and do a grep function against the /etc/passwd
c)it will save that output to /tmp/result..
but my script is just hanging...
#!/usr/bin/perl -w
open(SIPFILE, "</tmp/sipfile")
or die "Couldn't find the /tmp/sipfile: $! \n";
open(RESULT, ">>/tmp/result");
my $line;
while (<SIPFILE>) {
$line = `grep $_ /etc/passwd`;
print RESULT $line;
}
close(SIPFILE);
close(RESULT);

NAME
sieveshell - remotely manipulate sieve scripts
SYNOPSIS
sieveshell [--user=user] [--authname=authname] [--realm=realm] [--exec=script] server[:port]
sieveshell --help
DESCRIPTION
sieveshell allows users to manipulate their scripts on a remote server. It works via MANAGESIEVE, a work in progress.
The following commands are recognized:
list list scripts on server.
put <filename> upload script to server.
get <name> [<filename>] get script. if no filename display to stdout
delete <name> delete script.
activate <name> activate script.
deactivate deactivate all scripts.
OPTIONS
-u user, --user=user
The authorization name to request; by default, derived from the authentication credentials.
-a authname, --authname=authname
The user to use for authentication (defaults to current user).
-r realm, --realm=realm
The realm to attempt authentication in.
-e script, --exec=script
Instead of working interactively, run commands from script, and exit when done.
