Shell Programming and Scripting

Bash reads different initialization files depending on whether it is interactive and whether it is a login shell. When you log in by hand and type pgp you will be in an interactive login shell. When you provide commands on the ssh command line you are switching to a non-interactive shell. The PATH to pgp is probably set up in one of the initialization files that is only read by interactive shells. The simplest fix would be to specify the full path to pgp. Alternatively try sourcing the files that bash loads automatically when started interactively.

@Wish thanks for quick reply.
