The find command in windows
Searches for a string of text in a file or files, and displays lines of text that contain the specified string.
Syntax
Parameters
Parameter | Description |
---|---|
/v | Displays all lines that don’t contain the specified . |
/c | Counts the lines that contain the specified and displays the total. |
/n | Precedes each line with the file’s line number. |
/i | Specifies that the search is not case-sensitive. |
[/off[line]] | Doesn’t skip files that have the offline attribute set. |
Required. Specifies the group of characters (enclosed in quotation marks) that you want to search for. | |
[ :][ |
]
Remarks
If you don’t use /i, this command searches for exactly what you specify for string. For example, this command treats the characters a and A differently. If you use /i, however, the search becomes non-case-sensitive, and it treats a and A as the same character.
If the string you want to search for contains quotation marks, you must use double quotation marks for each quotation mark contained within the string (for example, «»This string contains quotation marks»»).
If you omit a file name, this command acts as a filter, taking input from the standard input source (usually the keyboard, a pipe (|), or a redirected file) and then displays any lines that contain string.
You can type parameters and command-line options for the find command in any order.
You can’t use wildcards (* and ?) in file names or extensions that you specify while using this command. To search for a string in a set of files that you specify with wildcards, you can use this command within a for command.
If you use /c and /v in the same command line, this command displays a count of the lines that don’t contain the specified string. If you specify /c and /n in the same command line, find ignores /n.
This command doesn’t recognize carriage returns. When you use this command to search for text in a file that includes carriage returns, you must limit the search string to text that can be found between carriage returns (that is, a string that is not likely to be interrupted by a carriage return). For example, this command doesn’t report a match for the string tax file if a carriage return occurs between the words tax and file.
Examples
To display all lines from pencil.ad that contain the string pencil sharpener, type:
To find the text, «The scientists labeled their paper for discussion only. It is not a final report.» in the report.doc file, type:
To search for a set of files, you can use the find command within the for command. To search the current directory for files that have the extension .bat and that contain the string PROMPT, type:
To search your hard disk to find and display the file names on drive C that contain the string CPU, use the pipe (|) to direct the output of the dir command to the find command as follows:
Because find searches are case-sensitive and dir produces uppercase output, you must either type the string CPU in uppercase letters or use the /i command-line option with find.
поиск find
Выполняет поиск строки текста в файле или файлах и отображает строки текста, содержащие указанную строку. Searches for a string of text in a file or files, and displays lines of text that contain the specified string.
Синтаксис Syntax

Комментарии Remarks
Если вы не используете /i, эта команда ищет именно то, что указано для String. If you don’t use /i, this command searches for exactly what you specify for string. Например, эта команда обрабатывает символы и по a — A разному. For example, this command treats the characters a and A differently. Однако при использовании параметра /i Поиск выполняется без учета регистра, а в a A качестве того же символа обрабатывается и. If you use /i, however, the search becomes non-case-sensitive, and it treats a and A as the same character.
Если строка, которую нужно найти, содержит кавычки, необходимо использовать двойные кавычки для каждой кавычки, содержащейся в строке (например, «» Эта строка содержит кавычки «»). If the string you want to search for contains quotation marks, you must use double quotation marks for each quotation mark contained within the string (for example, «»This string contains quotation marks»»).
Если опустить имя файла, эта команда выступает в качестве фильтра, принимая входные данные из стандартного источника входных данных (обычно это клавиатура, канал (|) или перенаправленный файл), а затем отображает все строки, содержащие строку. If you omit a file name, this command acts as a filter, taking input from the standard input source (usually the keyboard, a pipe (|), or a redirected file) and then displays any lines that contain string.
Параметры и параметры командной строки для команды Find можно вводить в любом порядке. You can type parameters and command-line options for the find command in any order.
Нельзя использовать подстановочные знаки (* и ?) в именах файлов или расширениях, указанных при использовании этой команды. You can’t use wildcards (* and ?) in file names or extensions that you specify while using this command. Для поиска строки в наборе файлов, указанных с помощью подстановочных знаков, эту команду можно использовать в команде for . To search for a string in a set of files that you specify with wildcards, you can use this command within a for command.
При использовании /c и /v в одной командной строке эта команда отображает количество строк, которые не содержат указанную строку. If you use /c and /v in the same command line, this command displays a count of the lines that don’t contain the specified string. При указании параметра /c и /n в той же командной строке команда Find игнорирует параметр /n. If you specify /c and /n in the same command line, find ignores /n.
Эта команда не распознает возвраты каретки. This command doesn’t recognize carriage returns. При использовании этой команды для поиска текста в файле, который содержит символы возврата каретки, необходимо ограничить строку поиска текстом, который может быть найден между возвратами каретки (то есть строкой, которая не может быть прервана символом возврата каретки). When you use this command to search for text in a file that includes carriage returns, you must limit the search string to text that can be found between carriage returns (that is, a string that is not likely to be interrupted by a carriage return). Например, эта команда не сообщает о совпадении для строкового налогового файла, если между словами налога и файла происходит возврат каретки. For example, this command doesn’t report a match for the string tax file if a carriage return occurs between the words tax and file.
Примеры Examples
Чтобы отобразить все строки из Pencil.AD , которые содержат строку резкость карандаша, введите: To display all lines from pencil.ad that contain the string pencil sharpener, type:
Чтобы найти текст, «специалисты, обозначенные в документе только для обсуждения. To find the text, «The scientists labeled their paper for discussion only. Это не окончательный отчет «. It is not a final report.» в файле report.doc введите: in the report.doc file, type:
Для поиска набора файлов можно использовать команду Find в команде for . To search for a set of files, you can use the find command within the for command. Чтобы найти в текущем каталоге файлы с расширением bat, которые содержат строку строки, введите следующую команду: To search the current directory for files that have the extension .bat and that contain the string PROMPT, type:
Чтобы найти и отобразить имена файлов на диске C, которые содержат строковый ЦП, выполните поиск на жестком диске с помощью вертикальной черты (|), чтобы направить выходные данные команды dir в команду Find следующим образом: To search your hard disk to find and display the file names on drive C that contain the string CPU, use the pipe (|) to direct the output of the dir command to the find command as follows:
Так как поиск при поиске выполняется с учетом регистра, а dir создает прописные буквы, необходимо либо ввести строковый процессор в верхнем регистре, либо использовать параметр командной строки /i с командой Find. Because find searches are case-sensitive and dir produces uppercase output, you must either type the string CPU in uppercase letters or use the /i command-line option with find.
The find command in windows
Search for a text string in a file & display all the lines where it is found.
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 double quote characters » , they must be escaped by doubling to «»
This is in addition to enclosing the entire string in quotation marks: «The «»main»» event»
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.
Errorlevel
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.
Limitations
Find does not support wildcards, use FINDSTR instead.
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.
An empty string «» will normally match nothing, with the /v flag reversing the test, to match everything, but this will fail for any lines longer than 4091 characters long.
If names.txt contains the following:
To search for «Jones» in names.txt
If you want to pipe the output from a command into FIND use this syntax
You can also redirect like this
To search a folder for files that contain a given search string:
Count the number of lines in a file (like wc -l on unix).
The empty string «» is treated as never matching. The /v flag reverses the test, so now it matches everything and then /c returns the count:
“For my art, there is a common theme most of the time: it is using the things we can see to search for the world we cannot see”
FINDSTR — Search for strings in files, supports regular expressions.
ATTRIB — Find filename (rather than searching the file contents.)
Redirection — Spooling output to a file, piping input.
Escape chars, delimiters and quotes
Agent Ransack — Free File Searching Utility.
Powershell: Where-Object — Filter objects passed along the pipeline.
Equivalent bash command (Linux): awk/gawk — Find and Replace text within file(s)
How To Find Specified Strings In Files With Find Command In Windows From Command Line With Examples?
Windows operating systems provide the tool named find to search text files for a given term or string. Linux also have a command with the same name but it is used to search files and folders names not file contents. Windows find command is very simple and easy command to work.
Help information about the find command can be printed with the /? option like below.
Help
Syntax
Syntax of the find command provides options , string to search and file or drive or path to be searched.
Find String
We will simple made a search in files. We will do not provide any option. Given term will be search in given file , path or drive. In this example we will search the term ismail in C:\users.txt .
Find String
From output we can see that the term ismail is found. The filename also given because multi file search.
Search Multiple Files
In previous example we have searched single for for given string. Find command also supports for searching multiple file with a single command. We do not specify an option. We will just use * for file name. * means all files those exists given path. We can also specify a path before * .
Search Multiple Files
Or we will search a given paths all files.
As we see find command search all files like text, binary, picture etc.
Search Files With Specific Extension
Previous example show how to search all files without filtering them according to their extension. We can give specific extension to search. We will use * / asterisk again but we will also specify the extension of file. In this example we will search in text files where they extension is .txt
Search Files With Specific Extension
Print Line Numbers
While searching terms there may be more than one occurence of the given string. We may need to print the line number of the match. This can be done with /N option.
Print Line Numbers
As we can se from result USERS.TXT file line number 1 have a match
Ignore Case
While searching case sensitivity is important. The find command by default search case sensitive. We can change this behavior and search case insensitive mode. We will use /I option for this.
Ignore Case
Print Non Matching or Reverse Match
Find command have the ability to print reverse match or printing non matching lines. Using this options may create enourmous output according to the given files or files contents. We will use /V option for this feature.
Print Non Matching or Reverse Match
