Substring Extraction 9.2 in the Advanced Bash Scripting Guide The command says keep the 19 characters from the right of the string. I do have a problem with the string, it contains a space or tab at the end. echo in the above command seems to remove it but without the echo it remains and I need to add another line: var=${var// /}. No problem, but was curious to know if there is a better way.

you can do just var=${var: -19} btw

# End of File

Looking good! keep it up. Dieter

ok thanks, more to follow...

Try this: var=$(ifconfig -a | awk '/^eth0/ {print $5}')

Seems to work great, thanks! The next step is to get all the available MAC address', more to follow...
