Shell Programming and Scripting

I have defined variable in .profile file. This variable, I tried to use in a shell script
for the same session. In Shell script it is not finding this variable, but the same variable
on the console if I try to access by echo $var, it is giving me correct assigned value.

Can anyone, please guide me how to use variable defined in .profile in the shell script?

Did you export the variable to the environment before using it in the session?

Yes, I have exported this variable to environment by using,

export var

It doesnt work.

This is how you normally define it and use it:
In your profile you should have-
export SCRIPTSD_P=$HOME/2005/some_dir
#This is how you use it in your script-
$SCRIPTSD_P/perf_jobs.sh

This is not a solution but let me tell you some thing. Hopefully, you are not doing that in your shell script. One time I tried to change the value of $SCRIPTSD_P in a shell script and I re-executed my .profile from within the shell script. Ex:

#Some shell script
export $SCRIPTSD_P=$HOME/2005/some_new_dir
#re-executing the profile into the current session.
. $HOME/2005/.profile

But, for some reason $SCRIPTSD_P didn't take the new value. I never could find out why. Did you check to see if you are changing the variable's value.

What is your shell ?
How are you using the variable in the script ?
and
how you are running the script. ?

I have a Korn Shell.

In my script, if I need to read some file, then common path to file is in this variable.

fName=$Access_Dir/FileName.txt
awk '{print $0}' fName
Second line awk is symbolic, I have one awk operation with fName.

I am running this script from command prompt.

... although it's "symbolic", but...... shouldn't it be like so:
awk '{print $0}' $fName
