Top Forums Shell Programming and Scripting About reture with string and keep other "echo" info Post 302745387 by Scott on Monday 17th of December 2012 08:04:39 AM

That was clear, but doesn't change anything.

The variable ip which is set in the function is available after the function is called. You can use that to echo the IP address, without affecting anything else.

If you really want to use the value of $IP and keep the other stuff, send the other stuff to standard error.

Code:
#!/bin/bash
get_ip()
{
    ip=$(grep -B2 "00:01:02:03:04:05" ip_tmp.log |head -1 |awk '{print $2}')
    echo "............." >&2
    echo "Guest OS ip is $ip" >&2
    echo "............." >&2
     #rm ip_tmp.log
    echo $ip
}
IP=$(get_ip)
echo "IP is $IP"
