Hello Alanchia
I just added the answer to your question to the Sun:Solaris FAQ where you can read it.
However, as it take one day to be approved,
here is it for you:
at system level you have the file
/etc/profile
where you can put a PATH definition for everybody. Then every user should have a
$HOME/.profile file in which he/she can
modify the general PATH definition.
Example of $HOME/.profile (partially, only related to PATH):
OPENWINHOME=/usr/openwin ; export OPENWINHOME
PATH=$OPENWINHOME/bin:$OPENWINHOME/bin/xview:$OPENWINHOME/demo:$PATH:/usr/bin/X11
export PATH
