some utils for bash script.

I always use the bash as my devops script, while it's boring to write the condition judgement/echo statement/exit.

So, I want to make the bash script short and clear.

I have collected some useful functions into this repo, which save me a lot of time in the past few years.

Just source the utils.sh and write the code calling the functions.

You can just focus on the logical, not the bash syntax and expression

echo_separator

echo_step "1. begin to validate the params"

if_empty_then_exit "$1" "the first param required!"
FILE="${1}"
if_path_not_exist_then_exit "${FILE}" "file not exist"

VALUE=$(if_empty_return_default "${2}" 123)

You can Buy me a coffee:) link
