In bash, I want to get the Nth word of a string.
For instance:
- STRING="one two three four"
- N=3
- Result: "three"
What bash command/script could do this?
Thank you!

Alternatively you can put the space in quotes - IMHO this is more readable. i.e. echo $STRING | cut -d " " -f $N

An alternative
N=3
STRING="one two three four"
arr=($STRING)
echo ${arr[N-1]}

The `echo` isn't necessary and I don't know why you're replacing a space with a space. This works just fine: `arr=($STRING)`

I just modified an example of the web.. (stupid). Thanks for your comment. Updated.
