See pcre(3) for a + full description of syntax and semantics. + + If no files are specified, pcregrep reads the standard + input. By default, each line that matches the pattern is + copied to the standard output, and if there is more than one + file, the file name is printed before each line of output. + However, there are options that can change how pcregrep + behaves. + + Lines are limited to BUFSIZ characters. BUFSIZ is defined in + <stdio.h>. The newline character is removed from the end of + each line before it is matched against the pattern. + + + +OPTIONS + -V Write the version number of the PCRE library being + used to the standard error stream. + + -c Do not print individual lines; instead just print + a count of the number of lines that would other- + wise have been printed. If several files are + given, a count is printed for each of them. + + -ffilename + Read patterns from the file, one per line, and + match all patterns against each line. There is a + maximum of 100 patterns. Trailing white space is + removed, and blank lines are ignored. An empty + file contains no patterns and therefore matches + nothing. + + -h Suppress printing of filenames when searching mul- + tiple files. + + -i Ignore upper/lower case distinctions during com- + parisons. + + -l Instead of printing lines from the files, just + + print the names of the files containing lines that + would have been printed. Each file name is printed + once, on a separate line. + + -n Precede each line by its line number in the file. + + -r If any file is a directory, recursively scan the + files it contains. Without -r a directory is + scanned as a normal file. + + -s Work silently, that is, display nothing except + error messages. The exit status indicates whether + any matches were found. + + -v Invert the sense of the match, so that lines which + do not match the pattern are now the ones that are + found. + + -x Force the pattern to be anchored (it must start + matching at the beginning of the line) and in + addition, require it to match the entire line. + This is equivalent to having ^ and $ characters at + the start and end of each alternative branch in + the regular expression. + + + +SEE ALSO + pcre(3), Perl 5 documentation + + + + + +DIAGNOSTICS + Exit status is 0 if any matches were found, 1 if no matches + were found, and 2 for syntax errors or inacessible files + (even if matches were found). + + + +AUTHOR + Philip Hazel <ph10@cam.ac.uk> + + Last updated: 15 August 2001 + Copyright (c) 1997-2001 University of Cambridge. |
