wait normally returns the exit status of the last job which terminated. It may also return 127 in the event that n specifies a non-existent job or zero if there were no jobs to wait for. Because wait needs to be aware of the job table of the current shell execution environment, it is usually implemented as a shell builtin .
Command-line completion allows the user to type the first few characters of a command, program, or filename, and press a completion key (normally Tab ↹) to fill in the rest of the item. The user then presses Return or ↵ Enter to run the command or open the file.
The current process may wait for the child to terminate or may continue to execute concurrent computing. Creating a new subprocess requires enough memory in which both the child process and the current program can execute. There is a family of spawn functions in DOS, inherited by Microsoft Windows.
In computing, Bash (short for "Bourne Again SHell,") [6] is an interactive command interpreter and command programming language developed for UNIX-like operating systems. [7] Created in 1989 [ 8 ] by Brian Fox for the GNU Project , it is supported by the Free Software Foundation and designed as a 100% free alternative for the Bourne shell ( sh ...
The underlying program is no longer executing, but the process remains in the process table as a zombie process until its parent process calls the wait system call to read its exit status, at which point the process is removed from the process table, finally ending the process's lifetime.
The init system is the first daemon to start (during booting) and the last daemon to terminate (during shutdown). Historically this was the "SysV init", which was just called "init". More recent Linux distributions are likely to use one of the more modern alternatives such as systemd. Below is a summary of the main init processes:
Although the high-society site does give us a small gift in saying that we can open our stocking presents as soon as you wake up. ... more acceptable to wait until that lull between the morning ...
Typical Unix shells (bash, etc.) have no built-in registry of file types and associated default applications. Linux command-line tools with similar functions include xdg-open [8] and run-mailcap. On Cygwin, the command is implemented as the cygstart executable. [9] In PowerShell, the Invoke-Item cmdlet is used to invoke an executable or open a ...
