How to change environment by using a shell?
e.g.
For this laboratory we assume you‘re in the standard C or POSIX locale. The shell command locale should output LC_CTYPE="C" orLC_CTYPE="POSIX". If it doesn‘t, use the following shell command:
export LC_ALL=‘C‘
If I write a shell that contains this command, it won‘t work since the child shell only change it‘s own environment.
I need to use:
. ./shellname or
source ./shellname
