Bug#81084: boot-floppies: busybox's grep fail's to parse a legal regular expression properly
Package: boot-floppies
Version: 2.2.17
Severity: normal
certain RE's will fail to be matched. this is not an exhaustive list,
and i was unable to find a test suite to test all sorts of RE's.
to reproduce:
% cat grep-test
1/3 yes 0 spaces hi
2/3 yes 2 spaces hi
no illegal character (*) hi *
no illegal character ($) hi$
no illegal character (tab) hi
no illegal characters hi *$
3/3 yes 1 space hi
% grep 'hi *$' < grep-test
1/3 yes 0 spaces hi
2/3 yes 2 spaces hi
3/3 yes 1 space hi
% ./busybox grep 'hi *$' < grep-test
zsh: exit 1 ./busybox grep 'hi *$' < grep-test
work around: everything grep can do, sed can do. a complete sed is included
in boot-floppies.
% sed -ne '/hi *$/p' < grep-test
1/3 yes 0 spaces hi
2/3 yes 2 spaces hi
3/3 yes 1 space hi
