Unable to get "shell processing full" to work IOS15+ and IOS-XE

[enewburn1]

I understand that Cisco devices will accept Linux REGEX commands (eg grep, grep -v, more, etc) after being issued the command "shell processing full" from global configuration. I've tried this on ASR1K, ISR4K, Cat9K, and even a 2911 with IOS 15.x.x. All devices accept the command, but none of them actually give me the tools I'm looking for:

Example

switch#show ip interface brief | grep

The examples I've come across seem to suggest this is really easy - what am I doing wrong here?

Hi

What do you mean they don't give you the tools?
Are you trying to do ? after the pipe sign? If so you won't see the grep feature.
If you've enabled the shell processing full command then just use the grep command and it will work.

Francesco you are a genius! Sure enough that's exactly what it was. Mostly all I care about is running grep redirects for specific output. This now works great on our ASR-1000Xs, ISR-4Ks and Cat9Ks. Part of what I was doing wrong was running it with a 'do' while in config mode. This doesn't work - I have to run it directly from Priv EXEC.

You da man! Thank you
