Easy Bash是一个简单的bash库，旨在使脚本编写更方便。通过几步操作即可创建和运行脚本，包括添加选项、编写自定义函数和实现主函数。此外，脚本支持帮助消息显示、参数运行、详细模式、检查模式、配置文件生成等功能。

How to use it

Here is a step by step example to illustrate how easybash makes scripting easier.

Create your script

You can simply clone examples/template.sh.

git clone git@github.com:DBADaily/easybash.git
cd easybash
mkdir echo_dates
cp -a examples/template.sh echo_dates/echo_dates.sh
cd echo_dates/
vi echo_dates.sh

Step 1 - add your options as below

add_main_options() {
  ## custom options
  # add your options here
  add_options "s:" "start-date:" "START_DATE" "Y" "start date"
  add_options "e:" "end-date:" "END_DATE" "Y" "end date"
  ...
}

Step 2 - write your custom function

# custom function
echo_dates() {
  local lv_start_date="$1"
  local lv_end_date="$2"
  while [[ "${lv_start_date}" -le "${lv_end_date}" ]]; do
    echo_blue_bold "Processing for date ${lv_start_date}"
    log_trace "Work for date ${lv_start_date} done."
    lv_start_date=$(date -d "${lv_start_date} + 1 days" +'%Y%m%d')
  done
}

Step 3 - implement main function

main() {
  add_main_options
  parse_args "$@"

  # add your logic here
  if [[ "$CHECK_MODE" != "Y" ]]; then
    echo_dates "${START_DATE}" "${END_DATE}"
  elif [[ "$CHECK_MODE" == "Y" ]]; then
    log_warning "CHECK MODE. Ski
