[OT] Show nice columns of numers
Hi, my company is going to shoot a TV spot that will show me at work. The first thing my desktop will contain is some BSD/FreeBSD logo. As it will be a movie, not a photograph, I would like to have huge columns of numbers running over the screen or at least one window. Does somebody know a programm that produces such nice output? Thanks in advance.

As `man test' describes, the /bin/test executable does not recognize a == operator. Neither in `sh' nor in `bash' the `test' executable will be called (unless written as /bin/test). In both cases it is a builtin command. The Sh builtin works like the `test' executable; the Bash builtin recognizes ==.

/bin/sh does not read profile
Hi, from "man sh": Invocation [...] When first starting, the shell inspects argument 0, and if it begins with a dash (`-'), the shell is also consid- ered a login shell. This is normally done automatically by the system when the user first logs in. A login shell first reads commands from the files /etc/profile and then .profile in a user's home directory, if they exist. [...] I use Slim (X login manager) which calls exec /bin/sh - ~/.xinitrc I first wondered why none of my commands in "/etc/profile" and "~/.profile" got executed. Finally, I modified "/usr/src/bin/sh/main.c" to trace what files are read, recompiled the "sh" command and: the only file that is executed is "~/.shrc". I just cannot believe that FreeBSD has such a severe bug. What is going wrong here?

This is not FreeBSD-specific, though.
I still wonder why you rely on lines just containing
%r{^.*$} . Maybe you're doing a quick'n'dirty solution
but I'm quite sure you won't get along with a one-liner.

An obvious problem is that a semicolon is missing before the closing

sed -e '/\*address:/{n;[EMAIL PROTECTED]@replaceText @;}'
I'm almost sure your version won't work with GNU sed either.

I stopped reading it when Xsane appeared. Sorry for the noise.

Permissions and SANE/scanimage
Hi,
my scanner works perfectly when I log in in as root. As an
unprivileged user, I just get this error message:
$ scanimage -L
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
I ended up in a brute force attempt saying in /etc/devfs.conf:
perm * 0666
Still, this didn't work. Starting "truss" and "diff" relvealed the
following difference:
root:
open("/dev/ugen0.2",O_RDWR,00) ERR#6 'Device not configured'
open("/dev/ugen0.2",O_WRONLY,00) = 6 (0x6)
unprivileged user:
open("/dev/ugen0.2",O_RDWR,00) ERR#13 'Permission denied'
Even when saying something like
chmod 0666 /dev/ugen0.2
the permissions will be 0644 after the run of "scanimage -L".
Could somebody please enlighten me what's going on here? What did I miss
when installing Sane?
"pkg_info -Dx sane-backends" stays empty.
Thanks in advance.
Bertram
