pcregrep is not a valid option, but glark certainly is. Either, however, is an alternative (they don't have the same syntax, and they don't have the same features), _not_ a solution, and either way, the man page is still an issue, as well as compatibility problems which Steve addresses. Paul's proposition was:
>Proposed fix (without breaking boot): >By default, in ubuntu, /usr/bin preceded /bin in the path. So install grep without -P (no libpcre) in /bin during boot. >Then install grep with -P (with libpcre) in /usr/bin, once /usr is mounted. Is this doable? While this may be difficult, the alternative is to have a modified man page for grep, /and/ a patch for grep which removes -P from the help listings, and still not have -P -- grep -P is not supported https://launchpad.net/bugs/15051 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
