LOGIN command
The LOGIN command begins your timesharing job and connects you to your
log-in directory.
Format
@LOGIN /FAST (USER) name (PASSWORD) password (ACCOUNT)account -
(SESSION REMARK) remark
where:
name is your user name.
pwd is your secret password (which is not printed on
your terminal)
acc is an account name or number that you are authorized
to use.
remark is an optional remark of up to 39 characters that
identifies the terminal session for accounting
purposes. Check with INFORMATION JOB-STATUS.
Change with SET SESSION-REMARK.
/FAST is an optional switch that prevents the following:
processing of your LOGIN.CMD and COMAND.CMD files
and the system's LOGIN.CMD and COMAND.CMD files,
printing of system mail, and printing of the notice
of new mail. (Your system manager may remove this
switch from your system.)
Output
Acknowledgement of Valid Login
The system acknowledges a valid LOGIN command by printing
your job number, terminal number, and the current date and
time. In addition, it prints the date and time of your last
login. You can use this information to determine if another
user has learned your password and logged in to your account
since the last time you logged out.
Note that a batch job automatically logs in and logs out of
your account. The batch login sets the date and time of
your last login and should not be confused with illegal
access to your account.
Notice of User Mail and System Mail
When you log in, the system notifies you if another user has
sent you a message with one of the system mail programs.
The system then lists any system mail (mail sent by
privileged users to all users) that has accumulated since
your last login. Note that this mail appears in the log
file if a batch job is run for you between the time the mail
was sent and the time you logged in.
Output from Command Files
After a successful LOGIN, the system processes the LOGIN.CMD
and COMAND.CMD files in the directory defined by logical
name SYSTEM: and the command files in your login directory.
The files are processed in this order:
1. SYSTEM:LOGIN.CMD
2. LOGIN.CMD
3. SYSTEM:COMAND.CMD
4. COMAND.CMD
The system displays any output from the commands in these
files on your terminal. After execution of each command
file, the system displays the message "End of
file-name.CMD". If the last command in the command file is
a TAKE command with no arguments, this message is not
displayed.
Characteristics
Getting the Attention of the System
Before logging in, you may have to press any alphanumeric or
special character to display the system herald or greeting
and the @ prompt necessary for typing the LOGIN command.
If you are dialing in by telephone to a line declared
autobaud by the system manager, this initial character
enables the system to determine your terminal's speed
setting, as long as the speed is 300, 1200, 1800, 2400,
4800, or 9600. Type a second character if the terminal's
speed is 110 or 150. If your initial character(s) fails to
get the system identification message, press the BREAK key
twice, followed by another character(s).
Rights, Capabilities, and Charges
The LOGIN command gives you ownership rights to your log-in
directory, and any group rights established for you on the
public structure (usually named PS:). In addition, you are
granted whatever capabilities (for example, Maintenance,
Wheel) have been awarded to you, and can be sure that any
charges you incur for the use of system resources, such as
CPU time or the batch and printing systems, will be recorded
to your user name.
Hints
Commands in Files Executed at Log-in Time
For Affecting Entire Session or Current Level Only
Commands that affect your entire job, for example,
TERMINAL and DEFINE, belong in LOGIN.CMD. Commands
that affect only the current level of TOPS-20, for
example, many SET commands, must be put into COMAND.CMD
if you want them to be executed automatically after
every PUSH command as well as after LOGIN.
For Affecting Batch Jobs
As soon as one of your batch jobs logs in, the system
processes the command files in the directory defined by
logical name SYSTEM: and the command files in your
login directory. The files are processed in this
order:
1. SYSTEM:BATCH.CMD
2. BATCH.CMD
3. SYSTEM:COMAND.CMD
4. COMAND.CMD
Note that certain parameters of the batch job, for
example, its time limit and the name of its log file,
have already been set before these commands are
executed. Such parameters are set either to values
specified by switches in the SUBMIT command that starts
the batch job, or to default values in effect for the
job issuing this SUBMIT command. See also Hints - For
Affecting Nested Batch Jobs, below.
Avoiding Duplicate Commands in Command Files
After executing a SYSTEM: command file, the system
executes the file of the same name in your login
directory. The SYSTEM: command files may contain
commands that you already have in your own command
files. To avoid executing the same commands twice,
remove duplicate commands from your command files. To
display a SYSTEM: command file, give the command TYPE
SYSTEM:file-name.CMD.
For Affecting Nested Batch Jobs
By placing a SET DEFAULT SUBMIT command in your
BATCH.CMD file, you cause these defaults to be in
effect for a nested batch job, (a batch job started by
a SUBMIT command within the control file of another of
your batch jobs).
A Final TAKE Command
To suppress the display of the message "End of
file-name.CMD" after execution of a command file, make
the last command in the file a TAKE command with no
arguments.
Simplifying Log-ins
By using the SET DIRECTORY ACCOUNT-DEFAULT command you
cause subsequent LOGIN commands to require just your
user name and password.
Special Cases
Commands You Can Issue Before Log-in
You can give these commands and arguments before logging in:
Command Arguments
ATTACH
BREAK
DAYTIME
INFORMATION AVAILABLE
COMMAND-LEVEL
MAIL
TERMINAL-MODE
VERSION
LOGOUT
SET LATE-CLEAR-TYPEAHEAD
TIME-LIMIT
SYSTAT (except with subcommands LPT or OUTPUT)
TERMINAL
UNATTACH
Logging in to PTYs
You do not need to give a password when logging in under
your own user name to a PTY (pseudo-terminal).
Must Log In Within Five Minutes
If you do not log in within five minutes of your initial
CTRL/C, your job will be logged out automatically and you
will have to type CTRL/C again.
Logging in to Last Available Job Slot
If you attempt to log in to the last available job slot, the
system will not log you in but will send you an error
message instead. This job slot is intended for users who
wish to attach detached jobs using the ATTACH command. To
log in a new job you must wait until a current user logs
out.
Related Commands
ATTACH for joining to your terminal a
job that has already been
logged in
INFORMATION DIRECTORY for displaying the date and
time that you started the
current terminal session with
LOGIN.
LOGOUT for ending your timesharing job
SET ACCOUNT for changing your account
during a terminal session
SET DIRECTORY ACCOUNT-DEFAULT for specifying a default
account for subsequent log-ins
SET SESSION-REMARK for making or changing your
session remark during a
terminal session
