- GETTY(8) Minix Programmer's Manual GETTY(8)
- NAME
- getty - system login banner
- SYNOPSIS
- getty [banner ...]
- DESCRIPTION
- Getty displays a system identification banner, reads a user name from
- standard input and executes login with that name as argument.
- Getty uses its arguments separated by spaces as a login banner. The
- character sequences n, s and t are printed as newline, space and tab.
- Any other x prints that x. The character sequences %s, %n, etc. produce
- the same output as uname -s, uname -n, etc. The default banner is
- %sssReleases%rsVersions%vnn%nslogin:s
- The only other useful functionality offered by getty is that it can be
- suspended by signal SIGUSR1 and restarted by SIGUSR2. This allows a
- program such as modem(1) to temporarily claim a dialin line for dialout.
- SEE ALSO
- modem(1), ttytab(5), init(8).
- BUGS
- Getty should be taught about modems and modem lines. The signal trick is
- an awful hack.
