Search for a text string in a file & display all the lines where it is found.
Syntax FIND [/V] [/C] [/N] [/I] "string" [pathname(s)]
"string" : The text string to find (must be in quotes).
[pathname] : A drive/file(s) to search (wildcards accepted). /V : Display all lines NOT containing the specified string.
/C : Count the number of lines containing the string.
/N : Display Line numbers.
/I : Ignore the case of characters when searching for the string.
If a [pathname] is not specified, FIND will prompt for text input
or will accept text piped from another command.
(use CTRL-Z to end manual text input)
If searching for text that contains quote characters " , they should be escaped by doubling to ""
The FIND command will output a string of 10 dashes ---------- followed by the filename being searched, followed by any matching lines of text in the file.
FIND will return an ErrorLevel as follows:
0 String found in at least one of the files.
1 String not found
2 If any files in the list do not exist or if no files match a wildcard mask. An invalid switch is given.
If names.txt contains the following:
Joe Bloggs, 123 Main St, Dunoon Arnold Jones, 127 Scotland Street, Edinburgh
To search for "Jones" in names.txt
C:\> FIND "Jones" names.txt
---------- NAMES.TXT Arnold Jones, 127 Scotland Street, Edinburgh
If you want to pipe the output from a command into FIND use this syntax
C:\> TYPE names.txt | FIND "Jones"
You can also redirect like this
C:\> FIND /i "Jones" < names.txt >logfile.txt
To search a folder for files that contain a given search string:
C:\> FOR %G IN (*.txt) do (find /n /i "SearchWord" "%G")
Count the number of lines in a file:
C:\> TYPE myfile.txt | FIND "" /v /c
Although FIND can be used to scan large files, it will not detect any string that is positioned more than 1070 characters along a single line (with no carriage return) This makes it of limited use in searching binary or XML file types.
