That does what? Without an explanation of what you want it to do, the answer is an unequivocal no. And even if you did say what it should do, the answer is still probably no - 'echo' is rather strictly defined by POSIX to not take arguments because of back-compat reasons, so adding new arguments makes it tricky to still comply with POSIX. You'd have to have a REALLY strong argument for why your new option is worthwhile, and why it won't break existing scripts that use 'echo -u' and expect a literal '-u' to be output, based on POSIX rules. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
