Hello.

I’m not sure if this is a bug - I just wanted to let you know.
Thanks,
Tomek

——

When there is more than one column and we go beyond the number of columns with the -f option, the output is empty

$ echo "test1 test2" | cut -d' ' -f1
test1
$ echo "test1 test2" | cut -d' ' -f2
test2
$ echo "test1 test2" | cut -d' ' -f3

$

—— 

When there is only one column and we go beyond 1 with the -f option, the output remains the first column

$ echo "test1" | cut -d' ' -f1
test1
$ echo "test1" | cut -d' ' -f2
test1
$ echo "test1" | cut -d' ' -f3
test1

My setup:

$ cut --version
