in a terminal type

casapy

and the world of CASA will open its doors for you.

There are a number of options to casapy (see casapy --help): Options are:

   --rcdir     directory
   --logfile   logfilename              specify the name of the log file if other than casapy-DATE.log
   --maclogger                          will use the Mac Console program for the logger
   --log2term                           output the logger text in the terminal
   --nologger                           run without launching the logger
   --nologfile                          does not create a logfile
   --nogui                              will not open the logger GUI
   --colors=[NoColor|Linux|LightBG]     selects color theme for prompt task inputs
   --noipython                          does not launch ipython (useful when combined with the -c option)
   --release <VERSIOn>                  launches CASA version <VERSION> when installed as Linux rpm
   -r <VERSION>                         alias for --release
   -c filename-or-expression            execute a CASA python script from the command line
   --help                               print this text and exit

E.g. you can execute a CASA script script.py directly with the command

casapy -c script.py

You can also launch the plotms and viewer GUIs separately without starting CASA itself. To do so, type:

casaplotms

to launch plotms and

casaviewer

for the viewer.
