    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 .

  5. System.map - Wikipedia

    en.wikipedia.org/wiki/System.map

    In Linux, the System.map file is a symbol table used by the kernel. A symbol table is a look-up between symbol names and their addresses in memory. A symbol name may be the name of a variable or the name of a function. The System.map is required when the address of a symbol name, or the symbol name of an address, is needed.

  6. ext2 - Wikipedia

    en.wikipedia.org/wiki/Ext2

    The MINIX file system was used as Linux's first file system. The Minix file system was mostly free of bugs, but used 16-bit offsets internally and thus had a maximum size limit of only 64 megabytes, and there was also a filename length limit of 14 characters. [20] Because of these limitations, work began on a replacement native file system for ...

  7. Fold (higher-order function) - Wikipedia

    en.wikipedia.org/wiki/Fold_(higher-order_function)

    Folds are in a sense dual to unfolds, which take a seed value and apply a function corecursively to decide how to progressively construct a corecursive data structure, whereas a fold recursively breaks that structure down, replacing it with the results of applying a combining function at each node on its terminal values and the recursive ...

  8. Computably enumerable set - Wikipedia

    en.wikipedia.org/wiki/Computably_enumerable_set

    The set S is the range of a partial computable function. The set S is the range of a total computable function, or empty. If S is infinite, the function can be chosen to be injective. The set S is the range of a primitive recursive function or empty. Even if S is infinite, repetition of values may be necessary in this case. Diophantine:

  9. Linux namespaces - Wikipedia

    en.wikipedia.org/wiki/Linux_namespaces

    The Linux Namespaces originated in 2002 in the 2.4.19 kernel with work on the mount namespace kind. Additional namespaces were added beginning in 2006 [ 3 ] and continuing into the future. Adequate containers support functionality was finished in kernel version 3.8 [ 4 ] [ 5 ] with the introduction of User namespaces.
