Description William Hester 2000-11-20 06:58:47 UTC 
With a sample textfile containing:

GoodLine
GoodLine
Unknown
BadLine
GoodLine
GoodLine

"grep 'BadLine' -v -B1" will simply pass everything on like cat. 
It should just print "GoodLine" 4 times.  The same happens for -A and -C.
Comment 1 Bernhard Rosenkraenzer 2000-12-12 17:33:07 UTC 
How is this supposed to be wrong?
grep 'BadLine' -v will include anything but BadLine, meaning all instances of
GoodLine and Unknown.

Since -B1 asks for a context line, BadLine will be displayed as context for line
5.
