I always wanted to be able to control which directory grep should go into and which it should not when I use the recursive (-r) option. I wanted a way to exclude some cache or other meaningless directories from it. I am using grep version 2.5.1 on gentoo linux (grep-2.5.1-r8).<\/p>\n

I’ve just found a patch on the net that does exactly that! If you check this page: grep – Patches: patch #5051, Exclude Directories in Recursive…<\/a> you can download a patch for the current grep version.<\/p>\n

I’ll show you how to apply it on a gentoo distro. It’s really simple. I am assuming that you already use a portage overlay…say it lies inside your \/usr\/local\/portage dir.<\/p>\n

Lines that begin with “#” should be executed as root.
\nLines that begin with “— COMMENT:” should be read and applied.<\/p>\n


\n# mkdir -p \/usr\/local\/portage\/sys-apps\/grep\/files
\n# cp \/usr\/portage\/sys-apps\/grep\/grep-2.5.1-r8.ebuild \/usr\/portage\/sys-apps\/grep\/grep-2.5.1-r100.ebuild
\n# cp \/usr\/portage\/sys-apps\/grep\/files\/* \/usr\/local\/portage\/sys-apps\/grep\/files\/
\n# vi \/usr\/portage\/sys-apps\/grep\/grep-2.5.1-r100.ebuild
\n--- COMMENT: find the line that says KEYWORDS=\"alpha amd64 arm hppa ia64 m68k mips ppc ~ppc-macos ppc64 s390 sh sparc x86\" and change it to: KEYWORDS=\"~x86\" or your ~arch if it's another.
\n--- COMMENT: add this under src_unpack():
\nepatch \u201c${FILESDIR}\u201d\/${PN}-2.5.1-exclude-dir.patch
\n# echo \"=sys-apps\/grep-2.5.1-r100 ~x86\" >> \/etc\/portage\/package\/keywords
\n--- COMMENT: change ~x86 to your ~arch
\n--- COMMENT: download http:\/\/savannah.gnu.org\/patch\/download.php?file_id=9836 and save it as \"grep-2.5.1-exclude-dir.patch\"
\n# mv \/path\/to\/grep-2.5.1-exclude-dir.patch \/usr\/local\/portage\/sys-apps\/grep\/files\/
\n# cd \/usr\/local\/portage\/sys-apps\/grep\/
\n# ebuild grep-2.5.1-r100.ebuild digest
\n# emerge =sys-apps\/grep-2.5.1-r100
\n<\/code><\/p>\n

and that’s it. The patch is applied cleanly (at least on ~x86) that I tried it and the result is this:
\n
\n# mkdir -p ~\/foo\/bar
\n# mkdir -p ~\/foo\/zoo
\n# echo \"test123\" >> ~\/foo\/bar\/test1.txt
\n# echo \"test123\" >> ~\/foo\/zoo\/test2.txt
\n# cd ~\/foo
\n# grep -r -n test123 *
\nbar\/test1.txt:test123
\nzoo\/test2.txt:test123
\n# grep -r test123 * --exclude-dir=zoo
\nbar\/test1.txt:test123
\n<\/code><\/p>\n
