Enviroment variable setting?

ROOT
1

Hi:
after install root in my computer ,i set the enviroment variables as below :
$export ROOTSYS =/home/chenjh/root
$export PATH=$ROOTSYS/bin:$PATH
$export LD_LIBRARY_PATH=$ROOTSYS/LIB:$LD_LIBRARY_PATH

and it can run correctly.but when next time i log in ,I should set the enviroment variables .
is there any way that I can set the enviroment variables permanent?

Best regards
:unamused: :smiley:

Put these instructions in your startup shell script.
For example, if you use bash, add these statements in
.bash_profile
