| | Grep - Wikipedia, the free encyclopedia |
 | | Tcgrep is a rewrite of grep and uses Perl regular expression syntax. | | | There are many derivatives of grep, for example agrep which stands for approximate grep to facilitate fuzzy string searching, fgrep for fixed pattern searches, and egrep for searches involving more sophisticated regular expression syntax. | | | All these variations of grep have been ported to many computer operating systems. |

| | LinuxQuestions.org Man Pages Online |
| | Grep understands two different versions of regular expression syntax: "basic" and "extended." In GNU grep, there is no difference in avail- able functionality using either syntax. | | | Warning: grep --binary-files=text might output binary garbage, which can have nasty side effects if the output is a terminal and if the termi- nal driver interprets some of it as commands. | | | By default, TYPE is binary, and grep normally outputs either a one-line mes- sage saying that a binary file matches, or no message if there is no match. |

| | Info: (grep.info.gz) Usage |
| | If `grep' listed all matching "lines" from a binary file, it would probably generate output that is not useful, and it might even muck up your display. | | | To force GNU `grep' to output lines even from files that appear to be binary, use the `-a' or `--binary-files=text' option. | | | So GNU `grep' suppresses output from files that appear to be binary files. |

| | Grep - pattern searching utility |
| | Grep is used to search for a pattern or word in a file. | | | Another useful way to use grep is to search multiple files for a certain pattern. | | | For more information on the uses of the grep family of utilities, or for a listing of other flags which these programs accept, check the man pages on your system (man grep). |

| | GREP 8.0 Quick Start -- Find Regular Expressions in Files |
| | GREP scans either named input files or the standard input & input can be a named file, a pipe, or the keyboard. | | | GREP was originally written with plain text files in mind, but you can also use it quite well with binary files like word-processing files, databases, and executable programs. | | | GREP works just fine in batch files, but you need to be at your computer when running unregistered GREP so that you can answer that prompt. |

| | grep |
| | The grep utility shall search the input files, selecting lines matching one or more patterns; the types of patterns are controlled by the options specified. | | | Multiple -e and -f options are accepted and grep uses all of the patterns it is given while matching input text lines. | | | Similarly, since patterns are matched against individual lines (excluding the terminating s) of the input, there is no way for a pattern to match a found in the input. |

| | BBEdit Grep Tutorial |
| | The version of grep that is used in BBEdit is a very basic version, similar to UNIX's egrep. | | | Second of all, BBEdit's grep is greedy, which means it goes for the biggest match it can, even if there are smaller matches inside it. | | | Also, some things, like digits, are represented differently in different programs supporting grep expressions (for instance, BBEdit uses # to represent a digit, while Perl uses \d). |

| | The grep family of UNIX utilities (Summer 1995) |
| | The grep family of UNIX utilities is commonly comprised of grep, egrep, and fgrep. | | | For instance, if you have a data file with ten million records and wish to do a complex analysis on only half a million of them, grep is an easy way to reduce the input d ata stream to the analysis program. | | | Agrep is Ambiguous grep and allows selection of lines using regular expressions which "almost" match and it allows the user to define what "almost" means. |

| | Debian -- grep |
| | GNU grep is based on a fast lazy-state deterministic matcher (about twice as fast as stock Unix egrep) hybridized with a Boyer-Moore-Gosper search for a fixed string that eliminates impossible text from being considered by the full regexp matcher without necessarily having to look at every character. | | | The result is typically many times faster than Unix grep or egrep. | | | Even if you don't want to use it, other packages on your system probably will. |

| | Regular Expressions in grep |
| | The grep program is a standard UNIX utility that searches through a set of files for an arbitrary text pattern, specified through a regular expression. | | | By default, grep shows the lines that match (use -v to show those that don't match). | | | By default, grep ignores the context of a string (use -w to match words only). |

| | The standard Unix grep command has a ``-l'' (lowercase L, not capital I) option which says to simply list the matching filenames one at a time, rather than the lines that match. | | | The system-supplied grep command groks through both text files and binary files. | | | It has no arguments, although it understands ``-'' in the list of files to mean ``standard input'', and presumes that standard input is always a text file. |
