找不到Bash变量分配和命令 [英] Bash variable assignment and command not found

问题描述

我有一个Shell脚本，可以让我访问脚本中的全局变量，但是当我尝试创建自己的脚本时，它会响应:找不到命令.

I have a shell script that will let me access global variables inside the script, but when I try to create my own, it responds with: command not found.

#!/bin/bash
J = 4
FACE_NAME = "eig$J.face"
USER_DB_NAME = "base$J.user"

运行上面的脚本时，我得到:

When I run the above script I get:

./test1.sh line 2: J: command not found
./test1.sh line 3: FACE_NAME: command not found
./test1.sh line 4: USER_DB_NAME: command not found

有什么想法吗?我在Windows XP下使用Cygwin.

Any ideas?? I'm using Cygwin under Windows XP.

推荐答案

尝试一下(注意，我已经从=的任一侧移除了空格):

Try this (notice I have removed the spaces from either side of the =):

#!/bin/bash
J="4"
FACE_NAME="eig$J.face"
USER_DB_NAME="base$J.user"

在声明变量时，Bash不喜欢空格-最好将每个值都用引号引起来(但这并不那么重要).

Bash doesn't like spaces when you declare variables - also it is best to make every value quoted (but this isn't as essential).
