Set Variable Name in shell script permanently












0















I need to change variable name every time I ran script.
Lets say I have a variable



a="foo"
echo "Value is : $a"


and it will print



Value is foo


But in same script i am changing the variable value



$a="bar"


And if i run the script again it should print



Value is bar


Can we achieve that in unix?
