Redirect emails using alias script

Redirect emails using alias script
# vim /etc/aliases
command: |/bin/grep Subject >> /tmp/emailgrep.txt
commandperl: |/bin/test.pl
Pay attention on the permissions the email system will use the mail account, so set the permissions on the script
test sending the emails
# echo “test email 123” | sendmail command@localhost
Keep looking into the log:
# tail -f /var/log/syslog
Well if the stdin goes to Perl, baby you can do anything!
my test.pl is just a dumb one:
@lines = <STDIN>;
foreach $line (@lines) {
open FILE, “+>>”, “/tmp/emails.txt” or die $!;
print FILE $line;
}
close FILE
