if ( cond ) foo Run Code Online (Sandbox Code Playgroud) else但据我所知,你不能在这里添加。 “短”语法的工作方式与 bourne shell 中完全相同,只是您需要使用关键字set: % [ "howru" = 'howru' ] && set a = good || set a = not_good % echo $a good % [ "XXhowru" = 'howru' ]...

if ("$var" == "1") then echo "Variable is 1" endif 解释: 变量引用时应使用双引号,以防止变量为空时导致语法错误。 3. 逻辑错误 错误示例: 代码语言:txt 复制 if ($var > 10) then echo "Variable is greater than 10" else if ($var < 5) then echo "Variable is less than 5" else ec...
3. if then else 这和Bourne Shell的if then, if then else, if then elif 相似。语法如下 A. if (expression) then commands endif B. if (expression) then commands else commands endif C. if (expression) then commands else if (expression) then commands else commands endif 4. foreach 这和Bour...

if (expr) then . . . else if (expr2) then . . . else . . . endif如果expr 为true,则会执行直到第一个 else 之前的命令。否则,如果 expr2 为true,则执行位于 else if 与第二个 else 之间的命令。否则,将执行位于 else 与endif 之间的命令。

1、if结构,有以下几种: 注意,条件判断语句中的then关键字一定要与if/else if在同一行上,这点与bash不同. (1): if(Condition-Expression) then Commands endif (2): if(Condition-Expression) then Commands1 else Commnads2 endif (3): if(Condition-Expression-1) then ...
