Junos OS

Hello all

Wondering is it possible somehow with Juniper to match on something in a show command and also display the next or previous line(s)?

For instance in SROS (Alcatel/Nokia) you have the option of "pre/post-lines" or "-B/-A" in Linux.

Thanks

Hi, 

I found you could do this by dropping to the shell and executing the commands:

> start shell
% cli show interfaces terse lo0.0 | grep up
lo0.0                   up    up   inet     172.16.2.1          --> 0/0
% cli show interfaces terse lo0.0 | grep -A 1 up
lo0.0                   up    up   inet     172.16.2.1          --> 0/0
                                            192.168.99.1        --> 0/0

Hope this helps.

Hi Daniel,

On Junos box operational mode I am unsure if we have an option like that but you may have a hack via shell.

root@jtac% cli show chassis routing-engine > /var/tmp/test.txt

root@jtac% grep -C 5 "User" /var/tmp/test.txt

root@jtac% grep -A 5 "User" /var/tmp/test.txt

Excellent, I hadn't even thought of the shell

Still, would be very nice if they had it available from CLI.

Cheers!

For following lines on a single occurance you can use find instead of match.  Find will start the outpu with the matched text and all that follows it.
