How can I set variables to be used in scripts as well? They don't have to be global / system-wide, just the current session is sufficient. But for some reason they seem gone even if I run a script right from my current terminal.
Example:
foo=bar
echo "$foo"
output: bar
However if test.sh contains echo "$foo" and I do:
foo=bar
./test.sh
The output is empty. How do I set a scope for temporary variables with a terminal session that remains valid when executing scripts from that same session?

export foo=barwill set the global variable $foo to bar. You can also usefoo=bar ./test.shas a single command to set foo to bar for test.sh.
