Environmental variable

Question

I am newly for Ubuntu and I just downloaded mulval software packet to run it on my Ubuntu, but I still not clear that the instruction say this:

"The environmental variable MULVALROOT should point to this package's root folder

Include $MULVALROOT/bin and $MULVALROOT/utils in PATH"

I installed mulval in my home directory:

worravit@worravit-Aspire-5715Z:~/mulval$

I read some questions in this community but those of them differences from mine.

Could anyone give me clear instruction please?

Answer 1

In this case ~/mulval is mulval's root folder.

Edit your .profile file (run gedit ~/.profile) and add the following lines in the end:

# set variables for mulval
MULVALROOT="$HOME/mulval"
PATH="$MULVALROOT/bin:$MULVALROOT/utils:$PATH"

Save the file then log out and log in.
