GETTYTAB(5) BSD File Formats Manual GETTYTAB(5)
NAME
gettytab -- terminal configuration data base
SYNOPSIS
gettytab
DESCRIPTION
The gettytab file is a simplified version of the termcap(5) data base used to describe terminal lines. The initial terminal login process
getty(8) accesses the gettytab file each time it starts, allowing simpler reconfiguration of terminal characteristics. Each entry in the
data base is used to describe one class of terminals.
Where to run getty(8) processes is normally defined by ttys(5).
There is a default terminal class, default, that is used to set global defaults for all other classes. (That is, the default entry is read,
then the entry for the class required is used to override particular settings.) The default entry is also normally read by other programs
that present login prompts to the user, such as telnetd(8), in order to retrieve the values of the he, hn, im, and if capabilities.
CAPABILITIES
Refer to termcap(5) for a description of the file layout. The default column below lists defaults obtained if there is no entry in the table
obtained, nor one in the special default table.
Name Type Default Description
ab bool false Auto-baud speed select mechanism for the Micom 600 portselector. Selection is done by looking at how
the character `
' is garbled at 300, 1200, 4800, and 9600 baud.
al str NULL user to auto-login instead of prompting
ap bool false terminal uses any parity
bk str 0377 alternative end of line character (input break)
b2 str 0377 alternative end of line character (input break)
c0 num unused tty control flags to write messages
c1 num unused tty control flags to read login name
c2 num unused tty control flags to leave terminal as
ce bool false use crt erase algorithm
ck bool false use crt kill algorithm
cl str NULL screen clear sequence
co bool false console - add '
' after login prompt
cs bool false clear screen based on terminal type in /etc/ttys
ds str '^Y' delayed suspend character
dx bool false set DECCTLQ
ec bool false leave echo OFF
ep bool false terminal uses even parity
er str '^?' erase character
et str '^D' end of text (EOF) character
ev str NULL initial environment
f0 num unused tty mode flags to write messages
f1 num unused tty mode flags to read login name
f2 num unused tty mode flags to leave terminal as
fl str '^O' output flush character
hc bool false do NOT hangup line on last close
he str NULL hostname editing string
hn str hostname hostname
ht bool false terminal has real tabs
i0 num unused tty input flags to write messages
i1 num unused tty input flags to read login name
i2 num unused tty input flags to leave terminal as
if str NULL display named file before prompt, like /etc/issue
ig bool false ignore garbage characters in login name
im str NULL initial (banner) message
in str '^C' interrupt character
is num unused input speed
kl str '^U' kill character
l0 num unused tty local flags to write messages
l1 num unused tty local flags to read login name
l2 num unused tty local flags to leave terminal as
lc bool false terminal has lower case
lm str login: login prompt
ln str '^V' ``literal next'' character
lo str /usr/bin/loginprogram to exec when name obtained
mb bool false do flow control based on carrier
nl bool false terminal has (or might have) a newline character
nn bool false do not prompt for a login name
np bool false terminal uses no parity (i.e. 8-bit characters)
nx str default next table (for auto speed selection)
o0 num unused tty output flags to write messages
o1 num unused tty output flags to read login name
o2 num unused tty output flags to leave terminal as
op bool false terminal uses odd parity
os num unused output speed
pc str '
