z/OS V1R9.0 UNIX System Services Command ... - Christian Grothoff

tcsh
The shell synchronizes group, home, path, shlvl, term, and user with the
environment variables of the same names: whenever the environment variable
changes the shell changes the corresponding shell variable to match (unless the
shell variable is read-only) and vice versa. Although cwd and PWD have identical
meanings, they are not synchronized in this manner.
The shell automatically interconverts the different formats of path and PATH.
Table 32. tcsh Built-in Shell Variables
Variable Purpose
addsuffix If set, filename completion adds / to the end of directories
and a space to the end of normal files.
ampm This variable gives a user the ability to alter the time
format in their tcsh prompt. Specifically, ampm will
override the %T and %P formatting sequences in a user’s
prompt. If set, all times are shown in 12hour AM/PM
format.
argv The arguments to the shell. Positional parameters are
taken from argv. For example, $1 is replaced by $argv.
Set by default, but usually empty in interactive shells.
autocorrect If set, the spell-word editor command is invoked
automatically before each completion. (This variable is
not implemented.)
autoexpand If set, the expand-history editor command is invoked
automatically before each completion attempt.
autolist If set, possibilities are listed after an ambiguous
completion. If set to ambiguous, possibilites are listed
only when no new characters are added by completion.
autologout Set to the number of minutes of inactivity before
automatic logout. Automatic locking is an unsupported
feature on the z/OS platform. If you specify a second
parameter on the autologout statement (intending it to
be for autolock), this parameter will be assigned to
autologout. When the shell automatically logs out, it
prints ’autologout’, sets the variable logout to automatic
and exits. Set to 60 (automatic logout after 60 minutes)
by default in login and superuser shells, but not if the
shell thinks it is running under a window system (the
DISPLAY environment variable is set), or the tty is a
pseudo-tty (pty). See also the logout shell variable.
backslash_ quote If set, backslashes (\) always quote \, ’ (single quote) and
″ (double quote). This may make complex quoting tasks
easier, but it can cause syntax errors in csh scripts.
cdpath A list of directories in which cd should search for
subdirectories if they aren’t found in the current directory.
command If set, the command which was passed to the shell with
the -c flag.
complete If set to enhance, completion first ignores case and then
considers periods, hyphens and underscores (’.’, ’-’ and
’_’) to be word separators and hyphens and underscores
to be equivalent.
