40.Nm grep
--- 140 unchanged lines hidden (view full) ---
181Specify a pattern used during the search of the input:
182an input line is selected if it matches any of the specified patterns.
183This option is most useful when multiple
184.Fl e
185options are used to specify multiple patterns,
186or when a pattern begins with a dash
187.Pq Sq - .
188.It Fl Fl exclude
189If specified, it excludes files matching the given
190filename pattern from the search.
191Note that
192.Fl Fl exclude
193patterns take priority over
194.Fl Fl include
195patterns, and if no
196.Fl Fl include
197pattern is specified, all files are searched that are
198not excluded.
199Patterns are matched to the full path specified,
200not only to the filename component.
201.It Fl Fl exclude-dir
202If
203.Fl R
204is specified, it excludes directories matching the
205given filename pattern from the search.
206Note that
207.Fl Fl exclude-dir
208patterns take priority over
209.Fl Fl include-dir
210patterns, and if no
211.Fl Fl include-dir
212pattern is specified, all directories are searched that are
213not excluded.
214.It Fl F , Fl Fl fixed-strings
215Interpret
216.Ar pattern
217as a set of fixed strings
218(i.e. force

--- 27 unchanged lines hidden (view full) ---
249.Fl Fl binary-file Ns = Ns Ar without-match
250option.
251.It Fl i , Fl Fl ignore-case
252Perform case insensitive matching.
253By default,
254.Nm grep
255is case sensitive.
256.It Fl Fl include
257If specified, only files matching the
258given filename pattern are searched.
259Note that

261patterns take priority over
262.Fl Fl include
263patterns.
264Patterns are matched to the full path specified,
265not only to the filename component.
266.It Fl Fl include-dir
267If
268.Fl R

276.It Fl J, Fl Fl bz2decompress
277Decompress the

280.It Fl L , Fl Fl files-without-match
281Only the names of files not containing selected lines are written to

283Pathnames are listed once per file searched.
