Questions

• How do I use NEMO in a Unix Shell

Objectives

• Loading NEMO interactively in your shell

• Ensure NEMO is present each time you start a new shell

In this lesson we will load NEMO into your shell environment.

Loading NEMO

It is assumed somebody has already installed NEMO. The only thing we need to know is the root directory where NEMO has been installed. So let us assume somebody told us that NEMO has been installed in /opt/nemo_4.1.1 The following command would then load NEMO in your bash shell

$ source /opt/nemo_4.1.1/nemo_start.sh

so really all you need is to find the location of the nemo_start.sh file. There is a similar file for the csh shell, for the die-hards.

Obviously you should test if NEMO commands are now available. The tsf (Type Structured File) program is the de-facto test for this.

$ tsf

Insufficient parameters, try 'help=', 'help=?' or 'help=h' or 'man tsf',
Formatted man page might also be here: https://teuben.github.io/nemo/man_html/tsf.1.html
Usage: tsf in=??? ...
type contents of a (binary) structured file

Making it persistent

Each time your (bash) shell is loaded, it will read some startup files, in which you can add the before mentioned source command. This way each time you start a new shell, NEMO will be ready. For bash this should be ~/.bashrc for interactive shells (interactive and login shells can give for confusing startup procedures).

There is a potential danger to this method. Side-effects for other programs. Probably should say more about that.
