For example struct tm and struct stat are often used by UNIX processes.
How you can see the presently running processes in Unix?
ps -ef
How many processes are running in a system find Unix command?
PS -e|cut -d " " -fname|wc -l
What is named and unnamed pipe in unix?
In Unix, pipes are basically how information flows between processes. Unnamed pipes are created and destroyed within the processes life cycle. Named pipes exist until removed with an unlink() command and can be used with unrelated processes.
What do you mean by 'processes' in unix environment?
A "process" is a program. In multitasking environments such as Unix or Windows - in fact, in most modern operating systems - the computer can run multiple processes at the same time. Note that not all of such processes need to have a visible window - some can be hidden from the user, until you use a special tool or command to list the processes.
Unix command to identify defunct processes?

What is UNIX IPC?
UNIX IPC (Inter-Process Communication) refers to a set of methods and mechanisms that allow processes to communicate and synchronize their actions within a UNIX operating system. It includes various techniques such as pipes, message queues, shared memory, and semaphores. These IPC methods enable processes to exchange data and coordinate their operations, facilitating efficient multitasking and resource sharing. Overall, UNIX IPC is essential for building complex applications that require cooperation between multiple processes.
Is UNIX supports multiprogramming?
Yes, UNIX supports multiprogramming, allowing multiple processes to run concurrently. This capability enables efficient resource utilization by sharing the CPU among various tasks, improving system performance and responsiveness. UNIX achieves this through process scheduling and management, ensuring that processes can execute simultaneously without interference.
What is Daemon Process in unix?
The word daemon is a word of Greek derivation meaning "worker". Daemon processes in Unix are background tasks that do things, such as printing, networking, task scheduling, etc.
What are the advantages of a Unix file system?
It is a system software and all the processes in the operating system can be controlled by the user.
Is unix a realtime operating system?
Some versions of Unix are oriented towards real time applications, and processes in Unix can be "promoted" to real time status if desired. Other than that, you would have to define more precisely what you mean by real time for an operating system.
What is similar to Unix?
Linux, Minix, Coherent, FreeBSD, etc. These are all clones of Unix
