Hi alex, Thanks, it works. Whille I still would like to know whether this is a way to specify "not equal" in mdb, so I can exclude the variables with some specific value, something like ::grep .!= 0x1234

Enclosure your comparison in quotes, such as:

... | ::grep '. != 0x1234'

The '!' character is a metacharacter that opens a pipe to an external shell command, so if you don't include the quotes it will try to spawn the program '0x1234' and pipe the output to it.

Thanks, Eric. This eliminates most of my doublts. Just want to be sure, it seems that from the below results, actually mdb taks '=' as the command, instead of taking 0x1234.

*swap_vnodes::array "struct vnode *" 0t2048 p |/Kn |::grep . != 0x1234

sh: =: not found
