退出状态1的含义由linux命令retured [英] Meaning of exit status 1 retured by linux command

问题描述

任何人都可以告诉mi，linux命令返回的退出状态1的含义。像127退出状态表示命令未找到。我访问过 http://linux.die.net/abs-guide/exitcodes.html page，是不是意味着退出状态1没有特殊的意义。

Can anybody tell mi that, what is meaning of exit status 1 returned by linux command. Like 127 exit status indicates "command not found". I have visited http://linux.die.net/abs-guide/exitcodes.html page, does it mean exit status 1 does not have particular special meaning.

推荐答案

零退出状态表示成功，而任何非零退出状态都是失败。

The only general convention is that a zero exit status signifies success, whereas any non-zero exit status is a failure.

许多 - 但肯定不是所有 - 命令行工具返回退出代码1

Many -- but certainly not all -- command-line tools return exit code 1 for syntax error, i.e. you had too few arguments or an invalid option.

很多 - 但是，唉，不是所有 - 命令行工具都有手动页面。按照惯例，它应该记录程序的退出代码，但许多不会。

Many -- but, alas, not all -- command-line tools have a manual page. By convention, it should document the exit codes of the program, but many do not.
