You can do:

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.
