<h2>System Commands</h2>
|
|
<p>
|
|
<b> sics_exitus </b>. A single word commands which shuts the server down. Only managers may use this command.</p>
|
|
<p>
|
|
<b> wait <i>time</i> </b> waits time seconds before the next command is executed. This does not stop other clients from issuing commands.</p>
|
|
<p>
|
|
<b> resetserver </b> resets the server after an interrupt.</p>
|
|
<p>
|
|
<b> dir </b> a command which lists objects available in the SICS
|
|
system. Dir without any options prints a list of all objects. The
|
|
list can be restricted with:
|
|
<dl>
|
|
<dt>dir var
|
|
<dd>prints all SICS primitive variables
|
|
<dt>dir mot
|
|
<dd>prints a list of all motors
|
|
<dt>dir inter driv
|
|
<dd> prints a list of all drivable objects. This is more then motors
|
|
and includes virtual motors such as environment devices and wavelength
|
|
as well.
|
|
<dt>dir inter count
|
|
<dd>Shows everything which can be counted upon.
|
|
<dt>dir inter env
|
|
<dd>Shows all currently configured environment devices.
|
|
<dt>dir match wildcard
|
|
<dd>lists all objects which match the wildcard string given in
|
|
wildcard.
|
|
</dl>
|
|
</p>
|
|
<p>
|
|
<b> status </b> A single word command which makes SICS print its current
|
|
status. Possible return values can be:
|
|
Eager to execute commands, Scanning, Counting, Running, Halted. Note that if a command is executing which takes some time to complete
|
|
the server will return an ERROR: Busy message when further commands are issued.
|
|
</p>
|
|
<p>
|
|
<b>status interest</b> initiates automatic printing of any status change in the
|
|
server. This command is primarily of interest for status display client
|
|
implementors.
|
|
</p>
|
|
<p>
|
|
<b>backup <i>[file]</i></b> saves the current values of SICS variables and selected
|
|
motor and device parameters to the disk file specified as
|
|
parameter. If no file parameter is given the data is written to the
|
|
system default status backup file.
|
|
The format
|
|
of the file is a list of SICS commands to set all these parameters
|
|
again. The file is written on the instrument computer relative to the
|
|
path of the SICS server. This is usually /home/INSTRUMENT/bin.
|
|
</p>
|
|
<p>
|
|
<b>backup motsave</b> toggles a flag which controls saving of motor
|
|
positions. If this flag is set, commands for driving motors to the
|
|
current positions are included in the backup file. This is useful
|
|
for instruments with slipping motors.
|
|
</p>
|
|
<p>
|
|
<b>restore <i>[file]</i></b> reads a file produced by the backup command described
|
|
above and restores SICS to the state it was in when the status was saved with
|
|
backup. If no file argument is given the system default file gets
|
|
read.
|
|
</p>
|
|
<p>
|
|
<b>restore listerr</b> prints the list of lines which caused errors during the
|
|
last restore.
|
|
</p>
|
|
<p>
|
|
<b>killfile</b> decrements the data number used for SICS file writing
|
|
and thus consequently overwrites the last datafile. This is useful
|
|
when useless data files have been created during tests. As this is
|
|
critical command in normal user operations, this command requires
|
|
managers privilege.
|
|
</p>
|
|
<p>
|
|
<b>sicsidle</b> prints the number of seconds since the last invocation of a counting
|
|
or driving operation. Used in scripts.
