Help on extracting a substring from the input string
Hi,

I am new to Unix. I am trying to extract a substring from an input string: Ex -

input string: deploy_v11_9_1
i want to extract and store the value v11_9_1 from the input string in a new variable.

I am using following command in my shell script file:
Code:
echo "Enter the folder name u want to access ... ";
read FOLDER;
version = $(echo $FOLDER | awk '{split($0,a,"_v");print a[2]}');
echo $version;

However, I am getting error message that
Code:
version: command not found

Could you please help?

Thanks,
Pranav
