Fish-shell: How can i test a string in another string ?

switch (uname -a | cut -d ' ' -f 1)
  case 'Darwin'
    echo 'do stuff'
  case 'Linux'
    echo 'do other stuff'
end

You could also use grep, especially if you wanted to do the same action for any of these.

if uname -a | grep 'Darwin\|Linux' >/dev/null
  echo 'do stuff'
end

thanks terlar .

hi terlar , i think your grep version is better , because i can detect if it is ubuntu , then i can define some function only work in Ubuntu . it's more specific .

thanks again .

Another way would be

switch (uname -a)
    case "*Darwin*"
        echo darwin stuff
    case "*Linux*"
        echo linux stuf
end

But I guess this question is answered, so I'll close it.
