pidof mongod && kill -SIGUSR1 $(pidof mongod) results in a new mongodb.log-File and the old file renamed to mongodb.log.2018-03-28T11-41-49. After renaming the file mongodb.log to mongodb.log_old by hand, mongod still logs into the old file (no problem, expected this).

Re: Kill doesn't send SIGUSR1 Maybe it should, but in your example it seems not to. If you send the same signal from a wide variety of sources, and you are recieving it in only one destination, and you observe the signal is not making the full trip - why conclude that *all* sources are failing? Because of this capability, kill() can also be considered as a communication mechanism among processes with signals SIGUSR1 and SIGUSR2. The pid argument can also be zero or negative to indicate that the signal should be sent to a group of processes.

That means if the process that receives a SIGUSR1 has been coded to handle it, it will do whatever action has been programmed for that signal. SIGUSR1 and SIGUSR2 are basically special signals that you can use for any defined purpose as opposed to the more commonly used signals like SIGINT, SIGQUIT and SIGKILL. And you wanted to kill the firefox process by its process id, then you'd do: kill -1 7667 Then you'd re-run the same ps command and check if the process was still running. If it is still running, then do a . kill -2 7667 working your way up to -9. To kill all processes started by your account, enter kill -1. kill -l 1) sighup 2) sigint 3) sigquit 4) sigill 5) sigtrap 6) sigabrt 7) sigbus 8) sigfpe 9) sigkill 10) sigusr1 11) sigsegv 12) sigusr2 13) sigpipe 14) sigalrm 15) sigterm 17) sigchld 18) sigcont 19) sigstop 20) sigtstp 21) sigttin 22) sigttou 23) sigurg 24) sigxcpu 25) sigxfsz 26) sigvtalrm 27) sigprof 28) sigwinch 29) sigio 30) sigpwr 31) sigsys 34) sigrtmin 35) sigrtmin+1 36) sigrtmin+2

kill( getpid(), SIGUSR1 ); The example above ensures that no signals are blocked from delivery. When the kill() function is called, the behavior is the same as calling the raise() function.

The following examples may be run using either version of kill. The process to be signaled is referred to by PID (process ID). If you're not sure of the process ID, you can find it with the ps command, for example ps -aux. kill 1234. Send the KILL signal to the process with PID 1234. kill 123 456 789. Kill three processes: PIDs 123, 456, and 789.

Although most commonly we’re using kill -9 and kill -15, there are a few more really useful signals that you should know about. We’ll use in place of a numeric process ID that will be specific to your needs. [Most Useful kill signals in Unix][kill-signals] SIGHUP (kill -1) SIGINT (kill -2) SIGQUIT (kill -3) SIGKILL (kill -9) SIGUSR1 (kill -10) User-defined signals: SIGQUIT, SIGABRT, SIGUSR1, SIGUSR2, SIGTERM. Each signal is represented by an integer value, and the list of signals that are available is comparably long and not consistent between the different UNIX/Linux variants. On a Debian GNU/Linux system, the command kill -l displays the list of signals as follows: sigusr1 ユーザ定義のシグナルで、プログラムによって意味が異なる。 ぱっと思いつくものでは dd で途中経過を表示させる用途に使われている。 Apr 17, 2019 · Locating the process (PID) to kill on Linux Each process is automatically assigned a unique process identification number (PID) in Linux. In this example it is 27707. Force kill process on Linux command line. To kill process on Linux use the kill command: kill pid kill -SIGKILL pid kill 27707 By default signal 15, named SIGTERM, is sent to kill The kill program allows you to send arbitrary signals to other Cygwin programs. The usual purpose is to end a running program from some other window when ^C won't work, but you can also send program-specified signals such as SIGUSR1 to trigger actions within the program, like enabling debugging or re-opening log files. The docker kill subcommand kills one or more containers. The main process inside the container is sent SIGKILL signal (default), or the signal that is specified with the --signal option. You can kill a container using the container’s ID, ID-prefix, or name.
