what is the correct content of the script
in order to have only one instance of the new PATH to add ??

Look in /etc/profile for a function called pathmunge.  This checks to see if the
new PATH component is already in the PATH and can be used with scripts in
/etc/profile.d.  The function is deleted after the scripts have been sourced.

You add a new path to the old path. Then it duplicates the path

Subject: Re: problem setting the PATH variable.
Still thank you, ... it works now.
 
But I have still another (little) problem:
 
To change the path, I wrote in the directory /etc/profile.d, a shell script with this content:
---
PATH=$PATH:/opt/netbeans/java/maven/bin
export PATH
-----
 
I don't understand because the output of the command echo $PATH is now;
--------
/usr/share/Modules/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/opt/netbeans/java/maven/bin:/opt/netbeans/java/maven/bin
-------
the PATH of "maven" is added two times...
 
what is the reason ???

Salve Angelo,

There is an error in the maven portion of the path:  it ends in mvn.  It
is supposed to end in bin.
