Terminate a running Murex function


fid-kill will terminate a running Murex function in a similar way that the POSIX kill (superficially speaking).


fid-kill fid


fid-kill doesn't send a kernel signal to the process since Murex is a multi-threaded shell with a single signal, fid-kill will send a cancellation context to any builtins executing (which covers builtins, aliases, public and private functions and any external executables running which were launched within the current Murex shell).

The FID (function ID) sent is not the same as a POSIX (eg Linux, macOS, BSD) PID (process ID). You can obtain a FID from fid-list.
