After I have apply the filter, I received output like below

```
command_set ="CmdAV=show ip policy <cr>"

```

But I need a output like below.

```
command_set ="show ip policy"

```

For the filed **command\_set** , **CmdAV=** is common and I need to remove **CmdAV=** keyword from the filed value.

I have tried gsub and it removed all word followed by the keypair.

Are there Any other method to resolve this

gsub is the right option but it sounds like you misconfigured it.
