Now I don't understand at all... See:
address@hidden jm58660]$ echo -e 'ABC\nDEF' | grep --perl-regexp '(?ms)C.*D'
address@hidden jm58660]$ echo -e 'ABC\nDEF' | grep --perl-regexp '(?ms)C.*D'
address@hidden jm58660]$ echo -e 'ABC\nDEF' | grep --perl-regexp '(?ms)C.*D'
ABC
DEF
address@hidden jm58660]$ echo -e 'ABC\nDEF' | grep --perl-regexp '(?ms)C.*D'
ABC
DEF
address@hidden jm58660]$ echo -e 'ABC\nDEF' | grep --perl-regexp '(?ms)C.*D'
ABC
DEF
address@hidden jm58660]$ echo -e 'ABC\nDEF' | grep --perl-regexp '(?ms)C.*D'
address@hidden jm58660]$ echo -e 'ABC\nDEF' | grep --perl-regexp '(?ms)C.*D'
address@hidden jm58660]$ echo -e 'ABC\nDEF' | grep --perl-regexp '(?ms)C.*D'
address@hidden jm58660]$
Same command, different output? Seems to be random, but how can this
be? Well, I am using beta kernel (Linux 2.5.73), but how could it make
grep behave like this? Version of grep is 2.5.1.
