Lines Matching full:patterns
10 \fBpcregrep\fP searches files for character patterns, in the same way as other
12 patterns that are compatible with the regular expressions of Perl 5. See
23 Patterns, whether supplied on the command line or in a separate file, are given

60 Patterns can be no longer than 8K or BUFSIZ bytes, whichever is the greater.
64 patterns are tried before the \fB-f\fP patterns.
66 By default, as soon as one pattern matches a line, no further patterns are
72 there are multiple patterns, they are all tried on the remainder of the line,
73 but patterns that follow the one that matched are not tried on the earlier part
76 This behaviour means that the order in which multiple patterns are specified

218 If \fB-f\fP is used with \fB-e\fP, the command line patterns are matched first,
219 followed by the patterns from the file(s), independent of the order in which

265 option applies only to the patterns that are matched against the contents of
266 files; it does not apply to patterns specified by any of the \fB--include\fP or
270 Read patterns from the file, one per line, and match them against

275 also the comments about multiple patterns versus a single pattern with
279 read. A data line is output if any of the patterns match it. A filename can
280 be given as "-" to refer to the standard input. When \fB-f\fP is used, patterns

330 If any \fB--include\fP patterns are specified, the only files that are
331 processed are those that match one of the patterns (and do not match an

544 Force the patterns to match only whole words. This is equivalent to having \eb
