SYNOPSIS
scriptname] char] file-descriptor] file-descriptor] string]
DESCRIPTION
The commands, including are targeted for removal from HP-UX; see the
below.
HALGOL is a simple language for communicating with devices such as
modems and X.25 PADs. It has simple statements similar to and that are
described below.
Options
recognizes the following options:
Causes to read script as the input program. If is not
specified, reads the standard input as a script.
Causes to use char as the first character in the input
stream instead of actually reading it from the
input descriptor. This is useful sometimes when
the program that calls is forced to read a char‐
acter but then cannot ``unread'' it.
Causes to use number for the output file descriptor
(i.e., the device to use for The default is 1.
Causes to use 'number' for the input file descriptor
(ie, the device to use for 'expect'). The default
is 0.
Causes to save this string for use when is encountered
in a command.
Causes to turn on debugging mode.
Causes to turn on verbose mode.
An script file contains lines of the following types:
(empty) Empty lines are ignored.
Lines beginning with a slash
are ignored (comments)
ID ID denotes a label, and is limited to alphanumer‐
ics or
string must be surrounded by double quotes. The text is
sent to the device specified by the option. Non-
printable characters are represented as in C;
i.e., as \DDD, where DDD is the octal ascii char‐
acter code. in a send string is the string that
followed the option.
Send a break "character" to the device.
Here number is how many seconds to wait before giving
up. 0 means wait forever, but this is not
advised. Whenever string appears in the input
within the time allotted, the command succeeds.
Thus, it is not necessary to specify the entire
string. For example, if you know that the PAD
will send several lines followed by an prompt,
you could just use as the string.
The program etc.) is run with the args specified. Do not use
quotes here. Also, the program is invoked
directly (using so wild cards, redirection, etc.
are not possible.
If the most recent expect or run encountered an error,
go to the label ID.
Similar to but does not fork.
Similar to but goes to standard error instead of to the
device.
Sets the program in debug mode.
It echoes each line to as well as giving the
result of each expect and run. This can be use‐
ful for writing new scripts. The command dis‐
ables this feature.
Sends subsequent incoming characters to
This can be used in the file as a security mea‐
sure, because part of the incoming data stream
contains the number of the caller. There is a
similar feature in it writes the time and the
login name into the same logfile. The command
disables this feature.
Similar to but better in some cases because it sends only
digits to the log file, and not other characters.
The command disables this feature.
Sets a global timeout value.
Each expect uses time in the timeout reservoir;
when this time is gone, the program gives up
(exit 1). If this command is not used, there is
no global timeout. Also, the global timeout can
be reset any time, and a value of 0 turns it off.
Exits with this value.
0 is success; anything else is failure.
To perform a rudimentary test of configuration files, run by hand,
using the option followed by the name of the script file. then sends
to standard output and expects from standard input; thus you can type
the input, observe the output, and use the command to see messages.
See the file for a good example of HALGOL programming.
WARNINGS
Use of commands, including is discouraged because they are targeted for
removal from HP-UX. Use ftp(1) or rcp(1) instead.
