Using output of file as new variable for bash script

Question

I'm trying to ping 2 different interfaces using the IPs generated by the following file.txt:

Eth1/1   ALL  ETHERNET   40   192.168.40.145  Device1-1  Eth16/1   192.168.40.144
Eth1/2   ALL  ETHERNET   40   192.168.41.145  Device1-2  Eth16/1   192.168.41.144

What I'm looking for is a script that allows me to first ssh into Device1-1 and ping 192.168.40.145 from source 192.168.40.144 then ssh into Device1-2 using a syntax like this:

ssh -q Device1-1 "ping 192.168.40.145 source 192.168.40.144" 
ssh -q Device1-2 "ping 192.168.41.145 source 192.168.41.144"

Is there any way I can open each ssh session in a different tab?

I'm having hard time to use different string characters from a text file as variables in a new script. There has to be a easy way to do this. Any suggestions?

Much appreciated!!!

Answer 1

You there is an easy way to do what you just described. If you use the -t flag in SSH you will execute the command right after logging in. Hope this helps. If not leave a comment so I can help some more. :)

• ssh -t Device1-1 'ping 192.168.40.145 source 192.168.40.144'

Answer 2

You can probably save the output in a new file source that.

awk '{print "ssh -q", "ping", $6, $5, "source", $NF}' file.txt > newfile.txt

The content of the newfile.txt

ssh -q ping Device1-1 192.168.40.145 source 192.168.40.144
ssh -q ping Device1-2 192.168.41.145 source 192.168.41.144

Source it.

source ./newfile.txt

Or maybe pipe the output to bash

awk '{print "ssh -q", "ping", $6, $5, "source", $NF}' file.txt | bash
