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

The echotc, settc and telltc commands can be used to manipulate and debug
terminal capabilities from the command line.
The tcsh shell adapts to window resizing automatically and adjusts the environment
variables LINES and COLUMNS if set.
tcsh built-in commands
The list below contains tcsh built-in commands which are not /bin/sh built-ins.
Descriptions for the tcsh built-in commands are found at “tcsh built-in command
descriptions” on page 673.
% filetest popd uncomplete
alloc glob pushd unhash
bindkey hashstat rehash unlimit
breaksw hup repeat unsetenv
builtins limit sched watchlog
bye login setenv where
chdir logout settc which
complete ls-F setty writedown
dirs notify source
echotc onintr telltc
Other tcsh built-in commands are also found in the z/OS shell. In some cases, they
may differ in function; see the specific command description for a discussion of the
tcsh version of the command.
: (colon) cd fg nice stop unset
@ (at) echo history nohup suspend wait
alias eval jobs printenv time
bg exec kill set umask
break exit newgrp shift unalias
As well as built-in commands, the tcsh shell has a set of special aliases:
beepcmd periodic shell
cwdcmd precmd
If set, each of these aliases executes automatically at the indicated time. They are
initially undefined. For more information about aliases, see “Alias substitution” on
page 640.
Descriptions of these aliases are as follows:
beepcmd
Runs when the shell wants to ring the terminal bell.
cwdcmd
Runs after every change of working directory. For example, if the user is
working on an X window system using xterm and a re-parenting window
manager that supports title bars such as twm and does
> alias cwdcmd ’echo -n "^[]2;${HOST}:$cwd ^G"’
then the shell will change the title of the running xterm to be the name of
the host, a colon, and the full current working directory. A fancier way to do
that is
> alias cwdcmd ’echo -n "^[]2;${HOST}:$cwd^G^[]1;${HOST}^G"’
