Software installed in /usr/local/bin can be run directly, since the PATH environment variable contains this value.

Software installed in /usr/local/contrib/bin can be run in two ways:

(The % in the examples is the unix prompt).

• Run the program directly using the complete path:

       % /usr/local/contrib/bin/prog_name
  

• Add the directory to the PATH environment variable, this can be done using the following command:

  For the bash shell:

       % export PATH=$PATH:/usr/local/contrib/bin
  

  For the tcsh shell:

       % setenv PATH "$PATH":/usr/local/contrib/bin
  

If you dont know which shell you are running, use the following command to find out:

     % echo $SHELL

If case of a conflict between programs in /usr/local/bin and /usr/local/contrib/bin, alias the new program name to make sure that the current program in the contrib directory is the one running.

For bash:

     % alias prog_name=/usr/local/contrib/bin/prog_name

For tcsh:

     % alias prog_name /usr/local/contrib/bin/prog_name

To check if aliasing worked, use the command alias to list all the aliases that you have.

In case you are having trouble running the software, file a ticket at: http://ticket.cs.pitt.edu explaining the problem in detail (use your AFS login and password).
