I just discovered, to my dismay, the following part of the cut man page:
-f, --fields=LIST
select only these fields; also print any line that contains no delimiter character, unless the -s option is specified
The -s option toggles the printing of lines with no delimiters.
In most cases, I would like lines with no delimiters to be considered as lines with a single field, so that:
Code:
$ echo "a" | cut -d' ' -f 1
would output a,
and
Code:
$ echo "a" | cut -d' ' -f 2
would output an empty line.
Is there an alternate version of cut where this is possible, or an option I don't know about?
As far as I understand, there is no option of cut that would return an empty line in the second case: if I use the -s option there is no line of output.
I can always use awk but in many cases this is not practical for me.

When cut encounters consecutive delimiters it seems to count each instance as a field, at least with spaces. Is this typical behavior for any delimiter?

Mandatory arguments to long options are mandatory for short options too.

select only these bytes
-c, --characters=LIST
select only these characters
-d, --delimiter=DELIM
use DELIM instead of TAB for field delimiter
-f, --fields=LIST
select only these fields; also print any line that contains no delimiter character, unless the -s option is specified
-n (ignored)
--complement
complement the set of selected bytes, characters or fields
-s, --only-delimited
do not print lines not containing delimiters
--output-delimiter=STRING
use STRING as the output delimiter the default is to use the input delimiter
-z, --zero-terminated

Use one, and only one of -b, -c or -f. Each LIST is made up of one range, or many ranges separated by commas. Selected input is written
in the same order that it is read, and is written exactly once. Each range is one of:
N N'th byte, character or field, counted from 1
N- from N'th byte, character or field, to end of line
N-M from N'th to M'th (included) byte, character or field
-M from first to M'th (included) byte, character or field
