<p>In <a href="/facts/Computing/Kghtm9fX">computing</a>, tree is a recursive <a href="/facts/Directory_(computing)/VLtLcEXY">directory</a> listing <a href="/facts/Command_(computing)/zUrvQbFy">command</a> or <a href="/facts/Computer_program/e38jH9N9">program</a> that produces a depth-indented listing of files. Originating in PC- and <a href="/facts/MS-DOS/fVrrz1uN">MS-DOS</a>, it is found in <a href="/facts/Digital_Research/9bYQl2pI">Digital Research</a> <a href="/facts/FlexOS/563z8WWo">FlexOS</a>, <a href="/facts/IBM/QszA7nwd">IBM</a>/<a href="/facts/Toshiba/QHRaw8Tr">Toshiba</a> <a href="/facts/4690_Operating_System/wEIsvjtF">4690 OS</a>, <a href="/facts/PTS-DOS/5LsVelfc">PTS-DOS</a>, <a href="/facts/FreeDOS/61fuGd0j">FreeDOS</a>, IBM <a href="/facts/OS%2f2/uVBl6ItP">OS/2</a>, <a href="/facts/Microsoft_Windows/bwhAhuSL">Microsoft Windows</a>, and <a href="/facts/ReactOS/BFmfC6BB">ReactOS</a>. A version for <a href="/facts/Unix/0pNL2seI">Unix</a> and <a href="/facts/Unix-like/YAKrAxzd">Unix-like</a> systems is also available.
</p><p>The tree command is frequently used as part of a <a href="/facts/Technical_support_scam/9Q6jXaaV">technical support scam</a>, where the command is used to occupy the command prompt screen, while the scammer, pretending to be technical support, types additional text that is supposed to look like output of the command.
