MARIADB-WAITPID(1) MariaDB Database System MARIADB-WAITPID(1)

# [NAME](#NAME)

mariadb-waitpid - kill process and wait for its termination (mysql\_waitpid is now a symlink to mariadb-waitpid)

# [SYNOPSIS](#SYNOPSIS)

**mysql\_waitpid \[options] pid wait\_time**

# [DESCRIPTION](#DESCRIPTION)

**mysql\_waitpid** signals a process to terminate and waits for the process to exit. It uses the kill() system call and Unix signals, so it runs on Unix and Unix-like systems.

Invoke **mysql\_waitpid** like this:

```
shell> mysql_waitpid [options] pid wait_time
```

**mysql\_waitpid** sends signal 0 to the process identified by *pid* and waits up to *wait\_time* seconds for the process to terminate. *pid* and *wait\_time* must be positive integers.

If process termination occurs within the wait time or the process does not exist, **mysql\_waitpid** returns 0. Otherwise, it returns 1.

If the kill() system call cannot handle signal 0, **mysql\_waitpid()** uses signal 1 instead.

**mysql\_waitpid** supports the following options:

•**--help**, **-?**, **-I**

Display a help message and exit.

•**--verbose**, **-v**

Verbose mode. Display a warning if signal 0 could not be used and signal 1 is used instead.

•**--version**, **-V**

Display version information and exit.
