Bug 36737

Summary: Man page/implementation inconsitency of diff -U
Product: Documentation Reporter: Niels Jansen <nhjansen>

Description Niels Jansen 2002-04-04 09:30:01 UTC 
Man page states that diff -U defaults to a context of 3 lines when a number of lines is not given. Not giving a number of lines however results in the following error:
diff: invalid context length argument

I know diff is contrib software, but i thought i'd send it in anyway.

How-To-Repeat: diff -U <fromfile> <tofile>

Well.. try reading the manual page again :)  The '-U' option *always*
takes an argument; it's the '-u' (lowercase) option that uses three
lines by default.

It would seem the documentation is correct in this case :)

G'luck,
Peter
