Question

I need to set some environment variables in Ubuntu. I do the following and it works:

export PATH="/home/vagrant/ns-allinone-2.35/bin:/home/vagrant/ns-allinone-2.35/tcl8.5.10/unix:/home/vagrant/ns-allinone-2.35/tk8.5.10/unix:$PATH"
export LD_LIBRARY_PATH="/home/vagrant/ns-allinone-2.35/otcl-1.14:/home/vagrant/ns-allinone-2.35/lib"
export TCL_LIBRARY="/home/vagrant/ns-allinone-2.35/tcl8.5.10/library"

But I move the same thing in a script envexport.sh and execute it, the environment variables are not getting set.

Where am I going wrong? How to accomplish this?

Thanks.

If you just run the script, the environment variables get destroyed when the script finishes.

Use . envexport.sh. That way the commands get executed in the current shell (environment).
