Package: grep Maintainer: Darwin Developers <firstname.lastname@example.org> Vendor: GNU Project Version: 2.4.2 URL: ftp://prep.ai.mit.edu/pub/gnu/grep/ Build-Depends: build-base, texi2html, perl Description: Get-Regular-Expression-and-Print grep searches the input files for lines containing a match to a given pattern list. When it finds a match in a line, it copies the line to standard output (by default), or does whatever other sort of output you have requested with options. . Though grep expects to do the matching on text, it has no limits on input line length other than available memory, and it can match arbitrary characters within a line. If the final byte of an input file is not a newline, grep silently supplies one. Since newline is also a separator for the list of patterns, there is no way to match newline characters in a text.
