variable one script to another

can a variable from one file be used in another so for instance

if say test.sh had

var="hello"

could i call that var form say test.1.sh

so it would display the var when i run test1.sh

basically i am writing a http interface with user input outputing that to a file and would like to use another file to exec all the variables

thanks in advance

Only if you source the script(s), and the variables are
exported ...

Cheers,

Tinkster is correct. Another alternative is to use the "." to read an initialization file.

EXAMPLE:
vi myenv =>

Code:

export ONE=1

export TWO=2

export THREE=tres

vi myscript =>

Code:

echo "BEFORE: ONE= $ONE, TWO= $TWO, THREE= $THREE."

. ./myenv

echo "AFTER: ONE= $ONE, TWO= $TWO, THREE= $THREE."

./myscript =>

Quote:

BEFORE: ONE= , TWO= , THREE= .
AFTER: ONE= 1, TWO= 2, THREE= tres.
