![]() ![]() For example, use the wildcard combination (.) And the repeating character (*) to match any character string. Special characters in regular expression syntax are most powerful when you use them together. x Exit: Use a super character x Word position: The end of the word Range: Any character in the specified range. Inverse class: Any one character not in the set. ^ Line position: Line header $ Line position: End of line Character class: Any one character in a set. Wildcard: Any character * Repeat: 0 or more occurrences of the previous character or class. ![]() The following table lists the characters that the findstr command accepts: A metacharacter is a symbol with special meaning (an operator or separator) in regular expression syntax. For example, letters and numbers are letter characters. The literal character is a character that has no special meaning in the regular expression syntax - it matches the appearance of that character. Regular expressions use both letter and super characters to find text samples, instead of exact strings.All findstr command line options must precede Strings and FileName in the command string.Specifies the location and file or files to search. a: Specify color attribute with two hexadecimal digits. Each directory must be separated by a semicolon ( ), for example dir1 dir2 dir3. ![]() d: Search for the specified directory list. g: Get a search string from the specified file. c: Use the text specified as a literal search string. ![]() f: Receive a list of files from the specified file. off Do not ignore files that have an offline property set. p Ignore files with unprintable characters. o Print offset characters before each matching line. m Print only the file name if the file contains matches. n Print the line number of each line with the appropriate result. v Print only lines that do not contain a match. i Ignore the case of characters when searching for strings. s Search the current directory and all subdirectories. r Handle the search string as a regular expression. e Match the text sample if it is at the end of the line. ParameterDescription / b Suitable for text samples if it is at the beginning of the line. Command syntax findstr findstr ] Parameters For an example of how to use this command, please see the example below. If you also want to match when the number is the last one on the line, so it has no, after it, you can use grep -E to enable extended regular expressions and then match either a 329 followed by a comma ( 329,) or a 329 that is at the end of the line ( 329$).The findstr command searches for text samples in files. So you're looking for: if grep -wq "329," myfile then *), and you don't need -e at all, that would be needed if you wanted to give more than one pattern. You also don't need the -F here, that is only useful if your pattern contains characters with special meanings in regular expressions which you want to find literally (e.g. That will match if you find your target string as a standalone "word", as a string surrounded by "non-word" characters. This option has no effect if -x is also specified. Word-constituent characters are letters, digits, and the Of the line or followed by a non-word constituent character. The test is that the matching substring must either beĪt the beginning of the line, or preceded by a non-wordĬonstituent character. Select only those lines containing matches that form whole The option you want is -w: -w, -word-regexp So it is only useful if you want to find lines that contain nothing other than the exact string you are looking for. The pattern and then surrounding it with ^ and $. Select only those matches that exactly match the whole line.įor a regular expression pattern, this is like parenthesizing That means (from man grep): -x, -line-regexp ![]()
