Subject: [PATCH] eplace `-v` Operator to Ensure Compatibility (#1185)

Replaced the `-v` operator with a more universally compatible method for variable checking in the bash script. The update uses parameter expansion to check if a variable is set, ensuring the script runs smoothly on environments with different Bash versions.
