If I issue a 'cp -a' on one konsole and a 'killall -s SIGINT cp' on
another konsole cp -a will terminate just as if it had finished copying.
Not quite; the exit status passed to the calling process will show the
signal used to terminate cp. This can in turn be used to diagnose a
display any desired message, for example in bash:
$ PROMPT_COMMAND='[ $? -ne 0 ] && echo Command exited abnormally'
$ true
$ false
Command exited abnormally
Alternatively it would be possible to construct a signal-aware wrapper
around cp and other interactive processes.
My regard would be to let it print something like 'copying interrupted'
(... and may be continued by issuing the same command once more).
As the tools already exist to build this feature it's not a good fit
for adding to cp. The specific message regarding resumed copies would be
highly dependent on the arguments to cp.
Cheers,
