kill: Send a `SIGUSR1` signal to all processes with the given GID (group id).
$ kill -${SIGUSR1} -${group_id}
try on your machine
This command is used to send the SIGUSR1 signal to a specific process group.
Here's the breakdown of the command:
- "kill" is the command used to send signals to processes in Unix-like operating systems.
- "-${SIGUSR1}" is the first argument passed to the "kill" command. This specifies the signal to be sent. In this case, it is the SIGUSR1 signal. SIGUSR1 is a user-defined signal that is often used by programs to trigger specific actions.
- "-${group_id}" is the second argument passed to the "kill" command. This specifies the process group ID to which the signal should be sent. Process groups are used to organize related processes together. The variable "group_id" would be replaced with the actual process group ID you want to target.
So, when this command is executed, it will send the SIGUSR1 signal to the specified process group, which will trigger any actions or behaviors associated with that signal in the targeted processes.
