What inferior OS are you running?

[...]
     The options are as follows:

     -b list
             The list specifies byte positions.

     -c list
             The list specifies character positions.
[...]

On FreeBSD, which tends toward the vanilla, you can 'cut -c -20,40-' or
whatever.  It is kind of overshadowed by its more powerful brethren, but
sometimes you just want to cut by character position.  And as Unix
commands goes, it has such an unusually straightforward name.
