sfk strlen phrase
tell the length of text lines supplied via stdin
or through command chaining, or tell the length
of a single string.
the result is printed to terminal, and supplied
as a return code to the command shell.
"sfk strlen" does not accept any options,
allowing to supply a string starting with "-".
options
-i read lines from standard input,
tell the longest line length.
-min tell the minimum, not the maximum length.
-minmax tell both min and max length.
-verbose tell minmax, line numbers and line text.
you may also type -all or -ver
-quiet do not print anything to terminal,
just provide the shell return code.
limitations
if the input contains stream text, i.e. text where
linefeeds are used only for paragraphs (not lines),
the result will be a paragraph length, and it can be
completely wrong if there are paragraphs longer than
4000 characters approx.
