Goals
Search for matching output in '

code:

show

' commands, similar to the use of the UNIX '

code:

grep

' parameter.
Use the pipe character to locate keywords in query command output.

Solution
Most '

code:

show

' commands are responsive to appending of the "

code:

|find

keyword

>" sequence, which provides filtering that has the effect of only displaying output lines that include the specified keyword string.

Here are some examples:

code:

show config policy |find cos 6

code:

set policy profile 1 name QoS pvid-status enable pvid 4095 cos-status enable cos 6

code:

set policy rule 1 iptos 104 mask 8 forward cos 6

code:

Here are some pointers for use of this command feature:

It simply filters output lines not containing an exact match to the <
```
keyword
```
> string value. If that string value does not appear when the command is executed without "
```
|find
```
", then there will be no output when the command is executed with "
```
|find
```
".
None of the command menu system, including the help menus, make mention of it.
None of the official documentation, including manuals and release notes, make mention of it.
There is no list of commands that either support it or don't support it. If not supported for a particular '
```
show
```
' command, then its inclusion with that command is simply ignored - no error message is generated.
The keyword is not case sensitive.
Do not add delimiters (e.g.
```
""
```
) to the keyword string, even if it includes spaces or special characters. Any included delimiters are assumed to be part of the keyword string value.
"
```
|find
```
" only works while CLI length is set to
```
0
```
(default). If "
```
|find
```
" is used while length is greater than
```
0
```
(e.g. '
```
set length 24
```
'), then both of these features are ignored during the '
```
show
```
' command execution. This is a known shortcoming, effectively FAD. It may be resolved in a future firmware release.

Also see this HowTo Video which explains the use of the Find and Loop parameters.
