Re: problem setting the PATH variable.

[Angelo Moreschini <mrangelo.fedora@xxxxxxxxx>]

I couldn't understand the reason for the double registration of the path :

(surly the script was executed twice).

I write (for the benefit of others) the solution I found:

(I modified the script with a condition).

---------

newpath="/opt/netbeans/java/maven/bin"
if [[ "$PATH" != *"$newpath"* ]]; then
    PATH=$PATH:/opt/netbeans/java/maven/bin
    export PATH
fi

---------

No, his script is correct (to do it for all users).

I expect he is running the PATH= command twice - once from
/etc/profile.d, and maybe once in his personal .profile or .bash_profile
or .bashrc.

Some applications (IDE?) appear to source /etc/profile when starting,

which is why we have the pathmunge function.   I think this is done so you

have the same PATH whether the app is run by clicking on a menu or by starting

it from a terminal.
