Concept
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. 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. The command is available in DOS, Digital Research FlexOS, IBM/Toshiba 4690 OS, IBM OS/2, Microsoft Windows, and ReactOS. On MS-DOS, the command is available in versions 2 and later. DR DOS 6.0 and Datalight ROM-DOS include an implementation of the command. The FreeDOS version was developed by Jim Hall and is licensed under the GPL. The Unix command find performs an entirely different function, analogous to on Windows. The rough equivalent to the Windows find is the Unix grep. 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.
