What about adding in GNU time 4 new qualifiers?

%T   1 if program terminated by a signal, empty otherwise
%S   signal number of program terminal by a signal, empty otherwise
%X   exit code if program terminated normal,
          or empty if terminated by a singal.
(Thanks Assaf Gordon)

And fours is
%N    signal's name (like SIGSEGV, segv, sigsegv, segmentation fault etc.), empty otherwise

Hope to feedback from you,

Turns out many single-letter specifiers are already taken.
I've used the following:


 %Tt = the strings 'normal' or 'signalled' or 'stopped' based on how
            the program exited.
 %Tx = numeric exit code IF the program exited normally (not signalled).
       empty otherwise.
 %Tn = numeric signal number IF the program was terminated by a signal.
       empty otherwise.
 %Ts = signal name IF the program was terminated by a signal.
       empty otherwise.


 $ ./time -q \
-f "exit type: %Tt\nexit code: %Tx\nsig-spec: %Ts\nsig-num:%Tn\n" \
                 ./tests/time-aux -S KILL -e 4
      exit type: signalled
      exit code:
      sig-spec: KILL
      sig-num: 9

      $ ./time -q \
-f "exit type: %Tt\nexit code: %Tx\nsig-spec: %Ts\nsig-num: %Tn\n" \
                 ./tests/time-aux -e 4
      exit type: normal
      exit code: 4


The code is available in a separate branch:

and here:



More testing and feedback is welcomed.

Once this stabilizes I'll add it to the GNU time master branch.
