A Perl enthusiast, I earn my living doing Unix/Linux system administration and light systems programming. In a former life I was an ALGOL systems programmer before finding my real love was for Unix. My education is scientific with a Master of Science degree.

comment How does Linux “kill” a process?
I'd add that since a kill -9 can't be caught, a process receiving it can't perform any cleanup (e.g. removing temporary files, freeing shared memory, etc.) before it exits. Hence, use kill -9 (a.k.a kill -kill) only as a last resort. Begin with a kill -hup and/or kill -term first and then use kill -kill as the final blow.

comment How to identify executable path with its PID on AIX 5 or more
I disagree specifically over point-3. Again, my disclaimer: I don't currently have access to an AIX machine. I would hope that you found something useful in my offerings, regardless.

Copy your executable to any directory; cd to the directory and launch the executable with a relative path. You can't assume anything.
