ÜMany of the commands given in Unix are really directives to the shell to start a child process. ÜWhen a process starts another process, the parent process suspends execution until the child process completes It is possible to direct the shell to start processes in the background ÜProcesses communicate with each other using a variety of

Update for Linux 3.3: As Zulakis wrote in a separate answer (+1 that), you can use ss from iproute2 to get a pair of inode numbers for each socket connection identifying local end and peer. This appears to be based on the same machinery as sock_diag(7) with the UNIX_DIAG_PEER attribute identifying the peer.

Unix (/ ˈ j uː n ɪ k s /; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. AIX is based on UNIX System V with 4.3BSD -compatible extensions. It is one of four commercial operating systems that have versions certified to The Open Group 's UNIX 03 standard (the others being macOS, HP-UX and eulerOS). The Unix operating system is a set of programs that act as a link between the computer and the user. The computer programs that allocate the system resources and coordinate all the details of the computer's internals is called the operating system or the kernel. Users communicate with the kernel through a program known as the shell.

A significant enhancement over … As we have seen in the previous chapter, every file or directory on a UNIX system has three types of permissions, describing what operations can be performed on it by various categories of users. The permissions are read ( r ), write ( w ) and execute ( x ), and the three categories of users are user/owner ( u ), group ( g ) and others ( o ). Nothing: there are three standard file descriptions, STDIN, STDOUT, and STDERR. They are assigned to 0, 1, and 2 respectively. What you are seeing there is an artifact of the way ls (1) works: in order to read the content of the /proc/self/fd directory and display it, it needs to open that directory. That means it gets a file handle, typically the UNIX Tutorial Three 3.1 Redirection Most processes initiated by UNIX commands write to the standard output (that is, they write to the terminal screen), and many take their input from the standard input (that is, they read it from the keyboard).
