how to set the Environment variable from shell Scrit
 

I want to set the CPLUS_INCLUDE_PATH from my shell script file.

I tried the following way

export CPLUS_INCLUDE_PATH=.:/home/XXX/ABC/Include

I ran the script and I checked in the console

echo $CPLUS_INCLUDE_PATH it did not show the newly added include path.

anybody can help me.:Pengy:

Thanks in advance.

Hi,

If you set/export a (environment) variable inside a script, it will be lost after the script stops.
Exporting variables can only be exported from parent to child, not from child to parent.

You can source a file. I.e:
infile contains export FOO=/tmp

. infile will make FOO available in the current shell.

Hope this clears things up a bit.

Thanks for your information.
