Unix Unix is a family ofoperating systemsoften used by high-endworkstationsand server computers. Unix operating systems use a modular design, with a primary systemkernel, a separate user interfaceshell, and hundreds of small utility programs. Some versions of Unix areproprietary software, while ...
What is a fork bomb? Aforkis a system call used in Unix and Linux systems that takes an existing process (a.k.a, a parent) and replicates it, forming a new process (a.k.a, a child). This allows both processes to carry out unique tasks simultaneously. ...

There can be various reasons for processes not being able to fork: There is a misbehaving service or process running, consuming more resources than expected. The system was not able to create new processes, because of the limits set for nproc in/etc/security/limits.conf. ...
People say “in UNIX, everything is a file”. And that we interact with the operating system through “file descriptors”. I don’t find this very enlightening. All it means is that the word “file” is overloaded to mean “some sort of resource”. Here are things that a file descript...
a这是个好主意。 This is a great idea.[translate] aIn Unix systems, a fork system call followed by an exec system call need to be performed to start a new process. The fork call clones the currently executing process, while the exec call overlays a new process based on a different execu...
Developed by Linus Torvalds, Linux is a product that mimics the form and function of a UNIX system, but is not derived from licensed source code. Rather, it was developed independently; by a group of developers in an informal alliance on the net. A major benefit is that the source code ...
