Shutdown is initiated with the exit
or quit
commands (they are
equivalent). Similar to startup, Octave has a shutdown process that can be
customized by user script files. During shutdown Octave will search for the
script file finish.m in the function load path. Commands to save all
workspace variables or cleanup temporary files may be placed there. Additional
functions to execute on shutdown may be registered with atexit
.
Exit the current Octave session.
If the optional integer value status is supplied, pass that value to the operating system as Octave’s exit status. The default value is zero.
When exiting, Octave will attempt to run the m-file finish.m if it
exists. User commands to save the workspace or clean up temporary files
may be placed in that file. Alternatively, another m-file may be scheduled
to run using atexit
.
See also: atexit.
Register a function to be called when Octave exits.
For example,
function last_words () disp ("Bye bye"); endfunction atexit ("last_words");
will print the message "Bye bye"
when Octave exits.
The additional argument flag will register or unregister
fcn from the list of functions to be called when Octave
exits. If flag is true, the function is registered, and if
flag is false, it is unregistered. For example,
after registering the function last_words
above,
atexit ("last_words", false);
will remove the function from the list and Octave will not call
last_words
when it exits.
Note that atexit
only removes the first occurrence of a function
from the list, so if a function was placed in the list multiple
times with atexit
, it must also be removed from the list
multiple times.
See also: quit.
