I run 'wc' on a file, .alias, containing 14 lines. It prints:
14 /home/hacksaw/.alias
'wc -l ~/.alias | cut -f1' produces the same thing. This is non-intuitive.
'wc -l ~/.alias | cut -f1 -d" "' produces a blank line
'wc -l ~/.alias | cut -f1 -d" "' produces
cut: the delimiter must be a single character
So cut is not a solution to print specific fields of input lines unless the delimiter
is exactly one character.
How often do the GNU utilities actually use tabs for that purpose? Obviously 'wc'
doesn't.
