-b Precede each line by the block number on which

numbers by
context (first block is 0).
-c Print only a count of the lines that contain
the pat-
tern.
-e pattern_list
Search for a pattern_list (full regular
expression
that begins with a -).
-f file
Take the list of full regular expressions from
file.
-h Suppress printing of filenames when searching
multiple
files.
-i Ignore upper/lower case distinction during
comparis-
ons.
-l Print the names of files with matching lines
once,
separated by NEWLINEs. Does not repeat the
names of
files when the pattern is found more than once.
-n Precede each line by its line number in
the file
(first line is 1).
-s Work silently, that is, display nothing except
error
messages. This is useful for checking the
error
status.
-v Print all lines except those that contain the
pattern.
-x Consider only input lines that use all
characters in
the line to match an entire fixed string or
regular
expression to be matching lines.
