I am unable to get the environment variables on linux.

Question

I am having .sh script and it contains "if" in it:

 if [ -z "$SOME_LIB" ]; then

    echo "Environment variable SOME_LIB is needed!"

    exit 1

    fi

Whenever I type “printenv” it displays that “SOME_LIB” contains the value "/usr/local/lib/python2.6 ". That path is correct. But the moment I run that .sh file from the terminal it displays: "Environment variable SOME_LIB is needed!"

How to run it properly?

Answer 1

There can be a case that variables are not set properly in the script so you can add printenv before your if command in the script.

You can also debug the script using set -x or run it using bash -x to make it display the value of the variable while checking.
