使用c-shell脚本设置环境变量

Question

I want to set some environment variables with script. I did something like that :

#!/bin/csh -f

setenv A "Hello"
setenv B "World"
source BlaBla

The script's name is for example "my_script"

So when I run : .my_script.

There are no errors but if I try to use these environment variables in the shell like this :

echo $A

I get "A :Undefined variable."

What can I do to solve this ?

Thanks.

Answer 1

Are you trying to use the variables in BlaBla or in the shell that runs my_script ?

They should be available in the context of the BlaBla script as-written.

If you want them available in the calling shell then you need to source my_script instead of /path/to/my_script which runs my_script in a new shell that cannot set shell variables in the calling shell.
