2017-01-09kill: optimizations for single-applet buildKang-Che Sung
* Fix a bug with a configuration in which the shell's kill builtin would be mistreated as a killall command (i.e. '-q' works, and 'kill process_name' succeeds when it shouldn't): CONFIG_ASH_JOB_CONTROL=y CONFIG_HUSH_KILL=y # CONFIG_KILL is not set CONFIG_KILLALL=y # CONFIG_KILLALL5 is not set * Optimize out unneeded code when the relevant applets are not selected. * Move kbuild lines about shells' kill builtins from Kbuild.src to kill.c, to accompany the new HAVE_SH_KILL macro. I hope this would make maintanence a little bit easier. Signed-off-by: Kang-Che Sung <explorer09@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2006-09-12Random cleanup hanging around my tree.Rob Landley
2006-07-12A couple things that got tangled up in my tree, easier to check in both thanRob Landley
untangle them: Rewrite u_signal_names() into get_signum() and get_signame(), plus trim the signal list to that required by posix (they can specify the numbers for the rest if they really need them). (This is preparatory cleanup for adding a timeout applet like Roberto Foglietta wants.) Export the itoa (added due to Denis Vlasenko, although it's not quite his preferred implementation) from xfuncs.c so it's actually used, and remove several other redundant implementations of itoa and utoa() in the tree.
2006-06-02- move #include busybox.h to the very top so we pull in the configBernhard Reutner-Fischer
and eventual platform specific includes in early.

Here is a patch for kill that I posted long ago, but forgot about until today. This allows kill to specify a negative process/group (such as -1). The shell already had this fix applied by Vodz some time ago.
