Setting default path in Unix

Question

I just installed valgrind on my Fedora12 machine.

$ valgrind                       // 1
$ valgrind: Command not found.   //error
$ /usr/local/bin/valgrind        // 2 works fine

My $PATH has /usr/local/bin in it.

Is there something else that I need to do to make 1 work?

Answer 1

it changes depending on your shell. In tcsh, for instance, do:

set path = ($path /usr/local/bin)

Answer 2

It worked after logging out and re-logging in the system.
