Hi, That worked, thanks!

I have 3 questions
Question 1 how can i set up such a way that when i input a,b, it only prints out that line ( kinda like search function)

e.g
username.txt
Code:
username@email.com:John:149.0.3.4:1
username1@email.com:Harry:149.0.3.4:1
username1@email.net:Alex:149.0.3.4:1
username1@email.edu:Nemo:149.0.3.4:1

if i input username@email.com as a, John as b
Output
Code:
username@email.com:John:149.0.3.4:1

Question 2 How do i only modify the value specified by the user?
e.g
Code:
#!/bin/bash


echo -n "Please enter email u which to modify:"
read a
echo -n "Please enter his name:-"
read b
echo -n "Enter new email:-"
read c
echo -n "Enter new name:-"
read d
echo -n "Enter new IP address:-"
read e
etc.. etc..

if a =username@email.com, b = John, c = Hello@yahoo.com, d = Lala, e =127.0.0.1
Output
Code:
Hello@yahoo.com:Lala:127.0.0.1:1
username1@email.com:Harry:149.0.3.4:1
username1@email.net:Alex:149.0.3.4:1
username1@email.edu:Nemo:149.0.3.4:1

Advanced Feature , how can i set up in such a way that if i input non characters(like numerals or weird symbols like !@#) for the input a and b, it returns a error message?

rt-email-dashboards(8)					     Request Tracker Reference					    rt-email-dashboards(8)

NAME

       rt-email-dashboards - Send email dashboards

SYNOPSIS

	   rt-email-dashboards [options]

DESCRIPTION

       This tool will send users email based on how they have subscribed to dashboards. A dashboard is a set of saved searches, the subscription
       controls how often that dashboard is sent and how it's displayed.

       Each subscription has an hour, and possibly day of week or day of month. These are taken to be in the user's timezone if available, UTC
       otherwise.

SETUP

       You'll need to have cron run this script every hour. Here's an example crontab entry to do this.

	   0 * * * * /usr/bin/perl /opt/rt4/local/sbin/rt-email-dashboards

       This will run the script every hour on the hour. This may need some further tweaking to be run as the correct user.

OPTIONS

       This tool supports a few options. Most are for debugging.

       -h
       --help  Display this documentation

       --dryrun
	       Figure out which dashboards would be sent, but don't actually generate or email any of them

       --time SECONDS
	       Instead of using the current time to figure out which dashboards should be sent, use SECONDS (usually since midnight Jan 1st, 1970,
	       so 1192216018 would be Oct 12 19:06:58 GMT 2007).

       --epoch SECONDS
	       Back-compat for --time SECONDS.

       --all   Ignore subscription frequency when considering each dashboard (should only be used with --dryrun for testing and debugging)
