2020-04-30grep: add proper support for pattern_listSören Tempel
From POSIX.1-2008: The pattern_list's value shall consist of one or more patterns separated by <newline> characters; As such, given patterns need to be split at newline characters. Without doing so, busybox grep will interpret the newline as part of the pattern which is not in accordance with POSIX. See also: https://bugs.busybox.net/show_bug.cgi?id=12721 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2020-04-29grep: Fix -f FILE when FILE is empty and -x providedGray Wolf
Grep currently special-cased empty pattern file to be the same as pattern file with one empty line (empty pattern). That does mirror how GNU grep behaves, except when -x is provided. In that case .* pattern needs to be used instead. Signed-off-by: Gray Wolf <wolf@wolfsden.cz> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2019-11-27grep: add -RTomi Leppanen
This adds -R option to grep similar to GNU grep.

2019-01-29grep: short-circuit -v to bail out on first matchAri Sundholm
A small optimization.

2019-01-29grep: fix -x -v with certain pattern ordersAri Sundholm
We found out that busybox -x -v is a bit broken: ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -e 'aa.*' -e '.*bb.*' aa bb cc ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -v -e 'aa.*' -e '.*bb.*' ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -e '.*aa.*' -e 'bb.*' aa bb cc ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -v -e '.*aa.*' -e 'bb.*' aa bb cc Last one is wrong. This patch fixes the issue by making sure that the variable 'found' never makes a transition from 1 to 0, as this would mean that grep previously found a match on this input line.

2017-10-31grep: skip grepping symlinks to directoriesJames Clarke
When grep is passed -r, recursive_action will treat any symlinks to directories not in the root as normal files, since it lstat's them and is therefore told they are not directories. However, file_action_grep will still try to fopen and read from them to see whether they match, which varies in behaviour across platforms. Linux will give EISDIR and thus grep will not find any matching lines, but FreeBSD will give the raw contents of the directory itself, which may match the given pattern. Also, if grep is passed -c, it will even print a count for these symlinks, even on Linux. Since this recursive_action behaviour is required for the correct functioning of other applets, such as tar, grep should handle this special case and skip any such symlinks. function old new delta file_action_grep 80 161 +81 Signed-off-by: James Clarke <jrtc27@jrtc27.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
