"command not found" when running shell script
提问by Axel Finkel
Here is the simple script.shfile I have:
这是script.sh我拥有的简单文件：
#!/bin/bash
pwd
date
ls -lg
I have used chmod +xto make the file executable, but when running it with ./script.shI get command not found: pwdcommand not found: dateand only the ls -lgcommand 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.
我曾经chmod +x使文件可执行，但是当./script.sh我使用 get运行它时command not found: pwdcommand not found: date，只有ls -lg命令有效。我有点困惑为什么前两个命令不起作用，因为当我在命令终端中输入它们时，它们会以应有的方式工作。

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.shto reveal those pesky characters.
也许那里有一个（隐形）角色不应该在那里。尝试在它将运行的环境（例如：Linux）中从头开始再次输入它，或者使用此命令od -c /folder/script.sh来显示那些讨厌的字符。

Also do not use a variable called PATH (cause it is already used :)
也不要使用名为 PATH 的变量（因为它已经被使用了 :)
