utterly useless unix command (uuuc)

Exactly what purpose does this command serve ?

/usr/bin/yes kreaper@testbox % file /usr/bin/yes /usr/bin/yes: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.4, dynamically linked (uses shared libs), for GNU/Linux 2.6.4, stripped


kreaper@testbox % /usr/bin/yes
y
y
y
y
y
y
^C
yikes!

kreaper@testbox % /usr/bin/yes "foobar" foobar foobar foobar foobar foobar foobar foobar foobar foobar foobar foobar foobar foobar foobar foobar ^C

And yes, they’ve even got a MAN page for this crap.

so that’s one additional command and a wasted pipe to achieve what a command should natively be programmed to do. not sold yet, BB ! :)

anything that requires a repetitive entry of ‘y’, for example. I highly recommend trying the following:

% yes | /bin/rm -i *

rajeev karamchedu: Unfortunately, no. I do not have access to Drupal (nor Active Directory, for that matter).

Mat: Can this be updated for Drupal 6?

Robert: I would also love to get a copy of this app. Thanks
