This script edits the /etc/tty.config file, then rebuilds all the tty
files (by calling bldttys). Several lines need to be changed for your
system, particularly the lines following the 'set w = `whereami`'.
----------------------------------------------------------------
#! /bin/csh
# J.Lepreau 9/81
# set verbose; set echo
if (`whoami` != "root") then
echo "Not allowed\!"
exit 1
endif
set w = `whereami`
if ($w == "cs" || $w == "gr") then
set sig = "HUP" # Vaxen are different!
else
set sig = 2
endif
set e = `printenv EDITOR`
if ("x$e" == "x") set e = "ex"
$e /etc/tty.config
if ($status == 0) then
/etc/bldttys
else
echo 'Bad status from edit: exiting'
exit 1
endif
if ($status == 0) then
echo "All tty files built"
echo "Poking init to re-merge /etc/ttys"
kill -$sig 1
else
echo 'Bad status from bldttys: exiting'
exit 1
endif
----------------------------------------------------------------
This script takes the file /etc/tty.config and rebuilds all the
tty files.
----------------------------------------------------------------
#! /bin/sh
# J.Lepreau, Univ of Utah 9/81 -- finally gave in to Randy!
awk -f /etc/bldttys.awk /etc/tty.config
echo 'New ttys were built' |/bin/mail lepreau
----------------------------------------------------------------
This awk program does the dirty work.
----------------------------------------------------------------
BEGIN { FS = "\t" }
{ if (NF > 0 && substr($1,1,1) != "#") \
{ \
dev = $2; type = $3; swit = $4; des = $5; \
printf "%s %s\n", type, dev > "/etc/ttytype"; \
printf "%s%s\n", swit, dev > "/etc/ttys"; \
printf "%s\t %s\n", dev, des > "/etc/tty.places"; \
} \
}
----------------------------------------------------------------
Finally, here is a sample tty.config file.
----------------------------------------------------------------
# /etc/tty.config -- IF THIS IS CHANGED, YOU MUST RUN /etc/bldttys !!
# Or better, use /etc/chgttys which does everything you want:
# edits this file, runs bldttys, and signals init to remerge.
# J.Lepreau, Univ of Utah 9/81
# Who reads the files output by bldttys:
# 1. /etc/tty.places no programs, just people
# 2. /etc/ttytype tset and login
# 3. /etc/ttys getty
# Tab is the field separator. Format, and where you get it from:
# arbitray-no. /dev/<foo> ttytype(termcap) ttys-entry(getty.types) location
