Hints for using third party software
In general, users need to be able to access software by adding a directory to the list of directories used for commands. That is called the search path and Unix uses a shell variable called path to keep track of those directories.csh/tcsh users should add the following to their .cshrc file:
set path = (NEWDIR $path)
sh/ksh users should add the following to their .profile file:
PATH=NEWDIR:$PATH; export PATH
where NEWDIR is shown below for the software that you need.
If you do not know which shell you are using, enter 'ps' to show processes.
