问题描述

在csh中,行的开始中的&符是做什么的?它似乎被忽略了(没有错误信息),但是为什么呢?

What does an ampersand at the beginning of a line do in csh? It seems to be ignored (with no error message), but why?

推荐答案

发现了一些有趣的东西:

Found something interesting:

% <command1> ; <command2>

&字符(&)相似 到分号(;),但不等待 < command1>完成.

The ampersand character (&) is similar to the semicolon (;) but does not wait for <command1> to finish.

也许它像对待空命令一样对待它?

Maybe it's treating it like an empty command?
