大佬教程收集整理的这篇文章主要介绍了linux bash中的条件代码块大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。

概述

几乎每个人都知道非常有用的&&和||操作符,例如: rm myf && echo "File is removed successfully" || echo "File is not removed" 我有一个问题:如何在&&之后放置一个命令块或||操作符没有使用这个功能? 例如,我想做: rm myf && \ echo "File is removed successfully" \
几乎每个人都知道非常有用的&&和||操作符,例如:
rm myf && echo "File is removed successfully" || echo "File is not removed"

我有一个问题:如何在&&之后放置一个命令块或||操作符没有使用这个功能?@H_801_19@

例如,我想做:@H_801_19@

rm myf && \
  echo "File is removed successfully" \
  echo "another command executed when rm was successful" || \
  echo "File is not removed" \
  echo "another command executed when rm was NOT successful"

该脚本的正确语法是什么?@H_801_19@

解决方法

rm myf && {
  echo "File is removed successfully" 
  echo "another command executed when rm was successful"
} || {
  echo "File is not removed" 
  echo "another command executed when rm was NOT successful"
}

或更好@H_801_19@

if  rm myf ; then
      echo "File is removed successfully" 
      echo "another command executed when rm was successful"
else
      echo "File is not removed" 
      echo "another command executed when rm was NOT successful"
fi
