In computing, find is a command in the command-line interpreters (shells) of a number of operating systems. It is used to search for a specific text string in a file or files. The command sends the specified lines to the standard output device.[1][2]

Overview

The find command is a filter to find lines in the input data stream that contain or don't contain a specified string and send these to the output data stream. It does not support wildcard characters.[3]

The command is available in DOS,[4] Digital Research FlexOS,[5] IBM/Toshiba 4690 OS,[6] IBM OS/2,[7] Microsoft Windows,[8] and ReactOS.[9] On MS-DOS, the command is available in versions 2 and later.[10] DR DOS 6.0[11] and Datalight ROM-DOS[12] include an implementation of the find command. The FreeDOS version was developed by Jim Hall and is licensed under the GPL.[13]

The Unix command find performs an entirely different function, analogous to forfiles on Windows. The rough equivalent to the Windows find is the Unix grep.[14]

Syntax

FIND [/V] [/C] [/N] [/I] "string" drive:][path]filename[...

Arguments:

  • "string" This command-line argument specifies the text string to find.
  • [drive:][path]filename Specifies a file or files in which to search the specified string.

Flags:

  • /V Displays all lines NOT containing the specified string.
  • /C Displays only the count of lines containing the string.
  • /N Displays line numbers with the displayed lines.
  • /I Ignores the case of characters when searching for the string.

Note: If a pathname is not specified, FIND searches the text typed at the prompt or piped from another command.

Examples

C:\>find "keyword" < inputfilename > outputfilename
C:\>find /V "any string" FileName
