Grep in IOS Output

[fb_webuser]

I would like to campaign for "grep" support in the Cisco IOS! It would be really awesome to type a command like sh run to get the configs for all dial-peers with a specific session target ip.

You mean like this?

show run | i dial-peer|session-target

?

include (or 'i') will include all lines that match the criteria.

section (or 's') will include entire sections that match.

Ex:

sh run | s dial-peer

sh run | i load

It is not quite as powerful as grep... but still very useful.

In addition to include and section - begin and exclude can also be used to pipe the output in IOS:

sh run | begin dial-peer                  <<< it will show output begin from the config from dial-peers

sh ip int brief | exclude unassigned   << when you try to do sh ip int brief and intrested in ip info only

Also if you need to get multiple sections:

show run | section dial-peer |dspf     - should show only dial-peer and dsp farm configs.

For include with multiple lines Aaron had already posted above.

I think these all should give you a lot of flexibility - when you want to view only a section from show run.

For me this was my mistake. I haven't route to do anything.

Cisco IOS supports regular expressions.  So you don't necessariyly have to use grep/egrep.

Hello fb_webuser

GREP is possible to run with show commands by enabling Cisco IOS Shell

try following: 

conf t 

shell processing full

exit

terminal shell (in exec mode)

now it is possible to run show commands with grep.

for example:

R1-2901#sh ver | grep 'cisco'
