Bash variable assignment and command not found [duplicate]

Question

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" 

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 

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

Answer 1

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" 

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

Answer 2

It's a good idea to use braces to separate the variable name when you are embedding a variable in other text:

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

The dot does the job here for you but if there was some other character there, it might be interpreted as part of the variable name.
