I am writing a shell script to start my network in my virtual machine on boot, since it does not do this right away for some reason with a snapshot of a virtual machine.

Since the eth device starts as being down, I have to get that device name with the following script and then start the device as well:

gateway=ifconfig -a | awk '/eth/ {print $1}'
dhclient $gateway

However I keep getting the following error, line 1: -a: command not found. ifconfig -a works however from the command line.

Is there a way to get ifconfig -a to work in my shell script?

You must use command substitution, otherwise, bash will think you assigned ifconfig result to variable gateway then run command -a:

gateway=$(ifconfig -a | awk '/eth/ {print $1}')
dhclient $gateway
  • thank you that works, I knew it had to do with how it was interpreting the script but couldn't pinpoint it. – jgr208 Jul 7 '14 at 16:14
  • The right single quote is wrongly placed. For some reason, stack exchange is too stupid to accept a minor edit. – Pavel Šimerda Jul 8 '14 at 5:01
