“找不到命令"；运行shell脚本时 [英] "command not found" when running shell script

问题描述

这是我拥有的简单的 script.sh 文件:

Here is the simple script.sh file I have:

#!/bin/bash
pwd
date
ls -lg

我已经使用 chmod + x 来使该文件可执行，但是使用 ./script.sh 运行该文件时，却找不到 command:pwd 找不到命令:date ，只有 ls -lg 命令有效.我对为什么前两个命令不起作用感到困惑，因为当我在命令终端中键入它们时，它们会按照应有的方式工作.

I have used chmod +x to make the file executable, but when running it with ./script.sh I get command not found: pwd command not found: date and only the ls -lg command works. I'm a bit perplexed as to why the first two commands aren't working because when I type them into the command terminal they work the way they should.

推荐答案

也许那里有一个(不可见的)字符，不应存在.尝试在将要运行的环境(例如Linux)中从头开始再次键入它，或使用此命令 od -c/folder/script.sh 来显示那些令人讨厌的字符.

Maybe there is a (invisible) character there that should not be there. Try typing it again from scratch in the environment that it will run (ex: Linux) or use this command od -c /folder/script.sh to reveal those pesky characters.
