-print: always returns true; prints the name of the current file plus a newline to the stdout.-print0: always returns true; prints the name of the current file plus a null character to the stdout. Not required by POSIX.-exec program [arguments...] ;: runs program with the given arguments, and returns true if its exit status was 0, false otherwise.
(For example, upon encountering a variable declaration, user-written code could save the name and type of the variable into an external data structure, so that these could be checked against later variable references detected by the parser.)
Beyond their uses in shells, globs patterns also find use in a variety of programming languages, mainly to process human input. A glob-style interface for returning files or an fnmatch-style interface for matching strings are found in the following programming languages: C# has multiple libraries available through NuGet such as Glob.
This mutually recursive definition can be converted to a singly recursive definition by inlining the definition of a forest: t: v [t[1], ..., t[k]] A tree t consists of a pair of a value v and a list of trees (its children). This definition is more compact, but somewhat messier: a tree consists of a pair of one type and a list another, which ...

Its name comes from the ed command g/re/p (global regular expression search and print), which has the same effect. [ 3 ] [ 4 ] grep was originally developed for the Unix operating system, but later became available for all Unix-like systems and some others such as OS-9 .
In computing, tree is a recursive directory listing command or program that produces a depth-indented listing of files. Originating in PC- and MS-DOS, it is found in Digital Research FlexOS, [1] IBM/Toshiba 4690 OS, [2] PTS-DOS, [3] FreeDOS, [4] IBM OS/2, [5] Microsoft Windows, [6] and ReactOS. A version for Unix and Unix-like systems is also ...
In computer science, a tail call is a subroutine call performed as the final action of a procedure. [1] If the target of a tail is the same subroutine, the subroutine is said to be tail recursive, which is a special case of direct recursion. Tail recursion (or tail-end recursion) is particularly useful, and is often easy to optimize in ...
