Question

我在一本书中找到了这个小shell脚本...... NGiNX只是这个脚本才起作用。因为每次我在/etc/init.d/nginx启动时（这是文件所在的位置）它都会向我发送以下消息：用法：/etc/init.d/nginx {start | stop | restart | reload}

出于测试目的，我添加了回音“$ 1”，当我这样做时它会发送给我：/etc/init.d/nginx start或其他任何东西......

我正在使用Ubuntu 12.04。

set –e正在将脚本的参数列表设置为–e。删除该行，脚本将起作用。

编辑：发布的脚本包含set –e（即EN DASH + e），而不是set -e（ASCII连字符/减号+ e）。这导致sh覆盖与–e一起传递的第一个参数，而不是在shell中设置-e选项。用–替换-可以解决问题。

我用于启动NGiNX的shell脚本无效
