Adding a path to the .bashrc file?

Question

At the moment I am trying to add a path for ns-2 to my .bashrc file, I have installed the ns-allinone-2.34 but the command ns gives the result: command not found when entere

Answer 1

The PATH should contain the directory for the binaries, not the binaries themselves.

For example, in the above:

export PATH=/home/michael/ns-allinone-2.34/bin/ns:..

should actually be:

export PATH=/home/michael/ns-allinone-2.34/bin:...
