sudo problems

I am trying to execute a command via sudo through ssh...

something like this...

ssh -t a@b "sudo command"

getting an error saying sudo: command not found

what could be the prb?

yes, it seems that sudo is not present on remote system.
-t option : Force pseudo-tty allocation - are you sure you want to use this ? You can simply omit "-t" it will work as well.

Sudo is installed on the remote system...sudo works when i login to the remote system without ssh. I have used -t bcuz i was getting a notif saying &TERM and -T is not specified.

ssh -t a@b "/full/path/sudo command"
