CSH UTILITIES

File Name Completion

In typing ®le names as arguments to commands, it is no longer necessary to type a complete name, only a unique abbreviation is necessary. When you want the system to try to match your abbreviation, press the ESC key. The system then completes the ®le name for you, echoing the full name on your terminal. If the abbreviation does not match an available ®le name, the terminal's bell is sounded. The ®le name may be partially completed if the pre®x matches several longer ®le names. In this case, the name is extended up to the ambiguous deviation, and the bell is sounded.

File name completion works equally well when other directories are addressed. In addition, the tilde (Ä) convention for home directories is understood in this context.

Viewing a File or Directory List

At any point in typing a command, you can request "what ®les are available" or "what ®les match my current speci®cation". Thus, when you have typed:

% cd Äspeech/data/bench/fritz/

you may wish to know what ®les or subdirectories exist (in Äspeech/data/bench/fritz), without aborting the command you are typing. Typing CTRL-Dat this point lists the ®les available. Files are listed in multicolumn format, sorted by column. Directories and executable ®les are identi®ed by a trailing / and *, respectively. Once printed, the command is re-echoed for you to complete. Additionally, you may want to know which ®les match a pre®x, the current ®le speci®cation so far. If you had typed:

% cd Äspeech/data/bench/fr

followed by a CTRL-D, all ®les and subdirectories whose pre®x was fr in the directory Äspeech/data/bench would be printed. Notice that the example before was simply a degenerate case of this with a null trailing ®le name. (The null string is a pre®x of all strings.) Notice also that a trailing slash is required to pass to a new sub-directory for both ®le name completion and listing. Note that the degenerate case

% ÄÃD

prints a full list of login names on the current system.

Command Name Recognition

Command name recognition and completion works in the same manner as ®le name recognition and completion above. The current value of the environment variable PATH is used in searching for the command. For example

% newa [Escape]

might expand to

% newaliases

Also,

% new [Control]-[D]

lists all commands (along PATH) that begin with new. As an option, if the shell variable listpathnum is set, a number indicating the index in PATH is printed next to each command on a [Control]-[D] listing.

Autologout

A new shell variable has been added called autologout. If the terminal remains idle (no character input) at the shell's top level for a number of minutes greater than the value assigned to autologout, you are automatically logged off. The autologout feature is temporarily disabled while a command is executing. The initial value of autologout is 60. If unset or set to 0, autologout is entirely dis- abled.

Command Line Control

A ÃR re-prints the current command line; ÃW erases the last word entered on the current command line.
