The kill(1) man page doesn't mention "kill 0".
/bin/kill 0 #scripts proceed no further
The bash man page mentions kill 0, but not in its main kill paragraph.
The bash man page doesn't mention kill -1.
The bash "help kill" bulrb doesn't mention kill 0 or -1.
The kill(1) man page, as of
procps:
Installed: 1:3.2.6-2.2
still looks a mess:
Name Num Action Description
()
()#very long wrapped line
0 0 n/a exit code indicates if a signal may be sent
