Comp.sources.misc: Volume 2, Issue 24
Submitted-By: Lenny Tropiano <lenny@icus.UUCP>
Archive-Name: sysinfo
[WARNING!!! I see a bug in the Makefile. The "install" commands do chown/
chgrp/chmod on the DIRECTORY, not the file. Fix it before you use it. ++bsa]
Here's a little ditty I wrote:
--- cut here --- --- cut here --- --- cut here --- --- cut here ---
#! /bin/sh
# This is a shell archive. Remove anything before this line, then unpack
# it by saving it into a file and typing "sh file". To overwrite existing
# files, type "sh file -c". You can also feed this as standard input via
# unshar, or by typing "sh <file", e.g.. If this archive is complete, you
# will see the following message at the end:
# "End of shell archive."
# Contents: README Makefile sysinfo.c
# Wrapped by lenny@icus.UUCP on Sun Jan 24 01:13:20 EST 1988
PATH=/bin:/usr/bin:/usr/ucb ; export PATH
if test -f README -a "${1}" != "-c" ; then
echo shar: Will not over-write existing file \"README\"
else
echo shar: Extracting \"README\" \(1842 characters\)
sed "s/^X//" >README <<'END_OF_README'
XI wrote this little ditty just to utilize the two lines on the bottom of
Xthe screen where the soft labels for the function keys are normally displayed.
XThis program will only work if you login on the console (obviously) and
Xyou aren't using the "user agent" or something that needs those two lines.
X
XI give thanks to Scott Hazen Mueller for his contribution of "newmgr.c"
Xthat initially gave me the idea for displaying the file system information.
X
XAfter unpacking the shar file, "su" and become root. Then type:
X
X # make install
X
XThis will copy the program into /usr/lbin (as defined by the Makefile) but
Xyou might just want to have this for your own "bin" directory, because
Xit is only useful if you run on a windowed device.
X
XThe mail file is only read for the number of messages if the modification
Xtime changes since the last read (saving on disk I/O). This program also
Xruns with a nice value of 5, and sleeps for 15 seconds between passes.
X(#defined by NICE and SLEEP respectively)
X
XYou might want to place the following lines in your /etc/localprofile
Xor .profile to activate sysinfo apon login:
X
XTTY=`tty`
Xif [ "`expr $TTY : '/dev/w' `" != "0" ]
Xthen
X sysinfo
Xfi
X
XPlease report any bugs, suggestions and problems to me:
