如何从文本文件中获取供bash脚本使用的变量值？

Question

I have a bash script, and I'd like it to read in the values of variables from a text file.

I'm thinking that in the text file where the values are stored, I'd use a different line for each variable / value pair and use the equals sign.

VARIABLE1NAME=VARIABLE1VALUE
VARIABLE2NAME=VARIABLE2VALUE

I'd then like my bash script to assign the value VARIABLE1VALUE to the variable VARIABLE1NAME , and the same for VARIABLE2VALUE / VARIABLE2NAME .

Since the syntax of the file is the syntax you would use in the script itself, the source command should do the trick:

source text-file-with-assignments.txt

alternately, you can use . instead of source , but in a case like this, using the full name is more clear.

The documentation can be found in the GNU Bash Reference Manual .
