Suspend and resume any program using SIGSTOP
I think that's the same as the old hint. SIGSTOP and STOP are just two names for the same signal. Same for SIGCONT and CONT.
Suspend and resume any program using SIGSTOP
Yes, that is correct. The signal names are SIGSTOP and SIGCONT, but kill lets you use shorthand for all the signals (by dropping the SIG in front.) You could also use the signal numbers (17 and 19, respectively,) which are all listed in /usr/include/sys/signal.h .
Suspend and resume any program using SIGSTOP
The SIGSTOP and SIGCONT signals work in bash and sh while only STOP and CONT seem to work in all the other shells I've tried. (csh, tcsh, zsh) Bash and sh can do it both ways as stated above.
Suspend and resume any program using SIGSTOP
That doesn't make sense, because it's the same
kill program getting the arguments either way.
Suspend and resume any program using SIGSTOP
Kill is a built-in shell utility, not a stand alone binary. Run this command:
And you get: kill: shell built-in command. |
