    You should have a look at info cut, which will explain what f1 means. Also, a same question here: question-7814205

    Actually we just need fields after(and) the second field. -f tells the command to search by field, and 2- means the second and following fields.

    echo "first second third etc" | cut -d " " -f2-

    You can use substring removal for that, no need for external tools:

    $ foo="a b c d"
    $ echo "${foo#* }"
    b c d

    Try doing this :

    echo "first second third etc"|cut -d " " -f2-
    

    It's explained in

     man cut | less +/N-
    

    N- from N'th byte, character or field, to end of line

    As far of you have the bash tag, you can use bash parameter expansion like this :

    x="first second third etc"
    echo ${x#* }

    You can do:

    echo "first second third etc" | cut -d " " -f2-
    >> second third etc
