linelen does not seem to be working as documented. Sample of the problem:
sfk linelen [options]
sfk strlen phrase
tell the length of text lines supplied via stdin
or through command chaining, or tell the length
of a single string.
[ . . . ]
sfk strlen "foo bar"
results in a string length of 7.
sfk filter foo.txt +linelen -all
list the shortest and longest line of foo.txt
C:\tmp>sfk filter foo.txt +linelen -all
error: unknown chain command: +linelen
C:\tmp>sfk ver -own

This is the latest version of sfk, and the syntax I use is identical to the help text.
This is a bug that will be fixed. For now, you may only use:
sfk filter foo.txt +strlen
and it will give you the largest line length.
Wow, thanks for the prompt reply. I discovered that I can get the min and max data with this syntax, also:
sfk linelen -i -all < foo.txt
