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.
