Without --tabs, --first-only is the default so specifying it is a no-op.

| * grep: add proper support for pattern_listSören Tempel2020-04-301-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported in bug 11441 when presented with a large number of quoted arguments xargs can return 'argument line too long': seq 10000 29999 | sed -e 's/^/"/' -e 's/$/"/' | busybox xargs echo This happens because the variant of process_stdin() which handles quoted arguments doesn't preserve state between calls. If the allowed number of characters is exceeded part way through a quoted argument the next call to process_stdin() incorrectly treats the terminating quote as a starting quote, thus quoting all of the argument separators. function old new delta process_stdin 274 303 +29 xargs_main 731 745 +14 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 43/0) Total: 43 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | | | | 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.
