Hi,
To limit the number of arguments of the echo command you have to quote them otherwise all words/symbols of the line following echo will be regarded as arguments for it. So to get what you want you need to write:
Code:
$ echo "line one" > "line 2"
In this case the filename "line 2" is also quoted because with '> line 2' the shell will put echo's output in 'line' and has no clue to what '2' is.
Regards
