How to Use all variables from one shellscript to another shellscript?

Linux
#1

HI Team,

I have two shell script with me a.sh and b.sh

Content in a.sh

#!/bin/bash

a=20

./b.sh

Content in b.sh

#!/bin/bash

echo “The value of a is $a”

When i run the script the value of a is not printing . Please let us know how to use variable from one shell script to another shell script

You can use “source” for load the another file

a.sh

#!/usr/bin/env bash

a='testing'

b.sh

 #!/usr/bin/env bash

 source a.sh
 echo $a

Executing

 ./b.sh
 testing
#3

HI ,

Thanks for your reply. It is working fine. But the problem is if i have more than 100 variables in a.sh script we cannot able to do source for all variables. Then in that case how to use a.sh variable to b.sh file

No problem, put all variables in another file shell for include, like this:

colorcodes.sh

#!/bin/sh
