export of a variable isn't working
Hi

I want export input data ...
Code:
echo "month: [ 04 ]"
read m
export m=$m

also
Code:
export m

is not working ?
the month-variable should be exportet for the use in other scripts,
but it is not working like this. What i'm doing wrong?

Thanks in advance!

Code:
echo "month: [ 04 ]"

is not a variable definition. It is just echoing some text.
When you use read, then you have to give it some input.

Example:
Code:
$> read m
1234
$> echo $m
1234
$> export m
$> env| grep ^m
m=1234
$> ksh
# echo $m
1234

If you read the variabale via another script you have to source that script, something like:
Code:
. ./scriptname

Hi zaxxon!

Thanks for your answer.
Sorry, my text is quit unclear.
This is the scriptcode ..
Code:
echo "month: [ 04 ]"
read m
export m=$m

.. and my input, for example 07 is been taken by read, but i cant export it by this way.
Is there any idea how to do this?

Thanks in advance!

Thanks for your answers, but the export command out of my script is not working. If i set the export m in the console it is working fine.

Replace
Code:
export m=$m

with
Code:
export m

in your script.
