Top Forums UNIX for Advanced & Expert Users Should I say "field 8" or "column 8" in this case? Post 302784611 by hanson44 on Friday 22nd of March 2013 02:55:06 PM

Yes, I think the sort syntax reinforces what I was trying to say. "sort -t, -k 8 fields.txt" sorts "field 8". The sort man page refers to "field separator" and "field number" and --field-separator. "column" is not even mentioned on the sort man page.

For the position within a field, both sort and cut use "character" instead of "column". In other words, cut says --characters where I would have said --columns. To me "characters" is confusing, as could be interpreted to be "--characters=ABC" as if looking for those "characters". The man pages says "select only these characters". Why did they choose --characters instead of --columns for the option name?

Of course, nobody is going to change the option name at this point. I suppose they could at least improve the cut man page, to say "select only these character positions".
