tcsh
Table 32. tcsh Built-in Shell Variables (continued)
Variable Purpose
prompt3 The string with which to prompt when confirming
automatic spelling correction. The same format
sequences may be used as in prompt (note the variable
meaning of %R). Set by default to CORRECT>%R
(y|n|e|a)? in interactive shells.
promptchars If set (to a two-character string), the %# formatting
sequence in the prompt shell variable is replaced with the
first character for normal users and the second character
for the superuser.
pushdtohome If set, pushd without arguments does pushd ^, like cd.
pushdsilent If set, pushd and popd do not print the directory stack.
recexact If set, completion completes on an exact match even if a
longer match is possible.
recognize_ only_ executables If set, command listing displays only files in the path that
are executable.
rmstar If set, the user is prompted before rm * is executed.
rprompt The string to print on the right-hand side of the screen
(after the command input) when the prompt is being
displayed on the left. It recognises the same formatting
characters as prompt. It will automatically disappear and
reappear as necessary, to ensure that command input
isn’t obscured, and will only appear if the prompt,
command input, and itself will fit together on the first line.
If edit isn’t set, then rprompt will be printed after the
prompt and before the command input.
savedirs If set, the shell does dirs -S before exiting.
savehist If set, the shell does history -S before exiting. If the first
word is set to a number, at most that many lines are
saved. (The number must be less than or equal to
history.) If the second word is set to merge, the history
list is merged with the existing history file instead of
replacing it (if there is one) and sorted by time stamp and
the most recent events are retained.
An example:
set savehist = ( 15 merge )
sched The format in which the sched built-in command prints
scheduled events. If not given, %h\t%T\t%R\n is used.
The format sequences are described under prompt; note
the variable meaning of %R.
shell The file in which the shell resides. This is used in forking
shells to interpret files which have execute bits set, but
which are not executable by the system (see “Built-in and
non-built-in command execution” on page 645. Initialized
to the (system-dependent) home of the shell.
shlvl The number of nested shells. Reset to 1 in login shells.
See also loginsh.
status The status returned by the last command. If it terminated
abnormally, then 0200 is added to the status. tcsh built-in
commands which fail return exit status 1, all other built-in
commands return status 0.
