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" \ 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？
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
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
