Hello.

I have a file test.sh , in file.txt I want save variables, the "ls" command runs well, but the other commands from the file fails, I want MP301,MP302,MP303 and MP304 be environment variables with full paths...what should I change?

If I execute MP301="pepe01.mp3" in the command line is ok.

Thanks
Kokolisso


$./mp3wrap-test2.sh
./mp3wrap-test2.sh: line 6: MP301="pepe01.mp3": command not found
./mp3wrap-test2.sh: line 6: MP302="pepe02.mp3": command not found
./mp3wrap-test2.sh: line 6: MP303="pepe03.mp3": command not found
./mp3wrap-test2.sh: line 6: MP304="pepe04.mp3": command not found
file.txt mp3wrap-test2.sh mp3wrap-test.sh


*********************BEGIN test.sh*********************************
#!/bin/bash


while read line
do
$line
done < file.txt

*********************END test.sh*********************************

And file.txt is

*********************BEGIN file.txt*********************************
MP301="pepe01.mp3"
MP302="pepe02.mp3"
MP303="pepe03.mp3"
MP304="pepe04.mp3"
ls

*********************BEGIN file.txt*********************************

You can either use source function (. file) or you can use eval.
Code:
while read line; do
    eval $line
done < file.txt


or just
Code:
. file.txt

Do notice the space between . and file.txt

Best regards

Hi Fredrik!

Thanks! The second option is just what I was looking for!
