沒有積累選項的外殼案例

Question

我希望選項-h可以單獨使用，而不用與任何其他選項累積（例如-h -l）。我該怎麼做？

case $1 in 
-h)help;; 
-f)aa;; 
esac 

case $2 in 
-l)bb;; 
esac 

case $3 in 
-p)cc;; 
esac 

謝謝。

示例代碼

#!/bin/bash                                   

    while getopts "ha" opt; do 
     case $opt in 
     a) 
      echo "-a was triggered!" >&2 
      ;; 
     h) 
      echo "-h was triggered!" >&2 
      ;; 
     esac 
    done 

測試用例

./example.bash -a -h 
-a was triggered! 
-h was triggered!
