It's possible this will not succeed if a process has blocked (masked) signals for some reason (such as being in a critical section). In such cases, the KILL signal (9) may be sent instead. The KILL signal cannot be blocked. Using kill -9 can create zombies, if my memory serves correctly. Oh, and 'kill -<number>' sends the signal corresponding to that number. The following commands are the same. kill <pid> kill -15 <pid> # man kill <...> SIGNALS The signals listed below may be available for use with kill. When known constant, numbers and default behavior are shown. Name Num Action Description 0 0 n/a exit code indicates if a signal may be sent ALRM 14 exit HUP 1 exit INT 2 exit KILL 9 exit cannot be blocked PIPE 13 exit POLL exit PROF exit TERM 15 exit > > The original OP screen-shots gave me a good laugh- it's always funny > to see Windows viruses attempting to run in Linux =) > Reminds me of the time a script kiddy owned my PPC Mac OS X machine and immediately notified me of his success by installing an x86 root kit, which of course rendered the machine unusable for the both of us. -Rob -------------- next part -------------- An HTML attachment was scrubbed...
