Introduction
The two commands used to show and set values for the
keywords that define the state of the instrument are
show and modify. For short, you can use
the commands s and m, respectively.
Thus, the command typed into a window on lrisserver
will display the current value for the keyword
ttime, the total exposure integration time:
s ttime
Similarly, the command
m ttime=100
will modify the total exposure time to 100 seconds.
These simple commands are actually aliases of:
show -s hires ttime
modify -s hires ttime=100
For a complete list of all of the keywords that can be
showed or modified, type s keywords. If you wish to
find only keywords attached to a certain stage, say the
comparison lamp system, pipe the command into the Unix
command grep:
s keywords | grep lamp
Examples
- Change the number of erase counts to 7:
m erasecnt=7
- To change the frame number to 1000.
m frameno=1000
Notes
- The DCS keyword library can also be accessed by typing:
show -s dcs keywords
This will only work on lrisserver.
