how to set environment variable with a given script
 

hi dear all,

i have to set environment variables , after the installation of intel(R)MKL for linux OS given in intel mkl user guide, which are INCLUDE, LD_LIBRARY_PATH, MANPATH, LIBRARY_PATH, CPATH, FPATH, NLSPATH using the script file which, in my case, is "mklvarsem64t.sh"

How can i set these environment variables?

Do i need to set all these variables?

Can anybody help me?

With Regards

Sonu

Variables set inside a script are only available inside that script, or more precisely, within the subshell running the script. It would be a security hole otherwise. So it's impossible to set an environment variable that will affect the system as a whole that way.

You have to set these variables with one of your startup scripts instead, if you want them to be available globally.

to set environment variables permanently use the .bashrc file in your home directory.
