Detect OS from Bash script and notify user

bash, string, system, uname

Solution

Rather than single quotes, you probably meant to use backticks:

OS=`uname -s`

but you really want

OS=$(uname -s)

Also, rather than an if statment, which will eventually become an if/else series, you might consider using case:

case $( uname -s ) in
Linux) echo Linux;;
*)     echo other;;
esac

Problem

Using bash, I want to find the operating system and notify the user. I tried: ``` OS='uname -s' echo "$OS" if [ "$OS" == 'Linux' ]; then echo "Linux" else echo "Not Linux" fi ``` I just get ``` uname -s Not Linux ``` on the terminal, which is wrong. How do I correctly set the string to what uname returns? Thanks
