Table 32. tcsh Built-in Shell Variables (continued)
Variable Purpose
version The version ID stamp. It contains the shell’s version
number (see tcsh), origin, release date, vendor, operating
system and machine (see VENDOR, OSTYPE, and
MACHTYPE environment variables) and a
comma-separated list of options which were set at
compile time. Options which are set by default in the
distribution are noted.
8b The shell is eight bit clean; default.
7b The shell is not eight bit clean.
nls The system’s NLS is used; default for systems
with NLS.
If Login shells execute /etc/csh.login before
instead of after /etc/csh.cshrc and ~/.login
before instead of after ~/.tcshrc and ~/.history.
dl ’.’ is put last in path for security; default.
nd ’.’ is omitted from path for security.
vi vi-style editing is the default instead of emacs.
dtr Login shells drop DTR when exiting.
bye bye is a synomym for logout and log is an
alternate name for watchlog.
al autologout is enabled; default.
kan Kanji is used and the ISO character set is
ignored, unless the nokanji shell variable is set.

hb The #! convention is emulated
when executing shell scripts.
ng The newgrp built-in is available.
rh The shell attempts to set the REMOTEHOST
environment variable.
afs The shell verifies your password with kerberos
server if local authentication fails. The afsuser
shell variable or the AFSUSER environment
variable override your local username if set.
An administrator may enter additional strings to indicate
differences in the local version.
visiblebell If set, a screen flash is used instead of the audible bell.
