ipcrm: Delete a semaphore by key.
$ ipcrm --semaphore-key ${semaphore_key}
try on your machine
The command ipcrm is used for removing System V interprocess communication (IPC) objects, such as shared memory segments, message queues, and semaphores. In this case, the command is used to remove a semaphore specified by the semaphore_key.
Here's a breakdown of the command:
ipcrm: The main command used to remove IPC objects.--semaphore-key: This option specifies that we want to remove a semaphore.${semaphore_key}: This is a placeholder for the actual semaphore key value. The value should be substituted with the desired semaphore key.
When executed, the command will remove the semaphore identified by the given semaphore_key, freeing up any system resources associated with it.
