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

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
