Searches for matching files in the current directory and all subdirectories. Findstr interprets all metacharacters as regular expressions unless you use /l. Uses search strings as regular expressions. Matches the pattern if at the end of a line. Prints seek offset before each matching line. Matches the pattern if at the beginning of a line. Skips files with non-printable characters. 'FINDSTR /C:"hello there" x.y' searches for "hello there" in file x.y.Searches for patterns of text in files using regular expressions.įindstr For example, 'FINDSTR "hello there" x.y' searches for "hello" or Use spaces to separate multiple search strings unless the argument is prefixed D:dir Search a semicolon delimited list of directories G:file Gets search strings from the specified file (/ stands for console ).

What are the undocumented features and limitations of the Windows FINDSTR command?įINDSTR ] strings filename ] /B Matches pattern if at the beginning of a line.No support of "zero or one of the previous" - "?".ĭoes not find anything in multiple Windows versions, but it should.No support of greedy iterators - "*?".Limitations of the regular expressions of findstr, as compared to grep: Works with binary files no less than text files. findstr /m Microsoft C:\Windows\system32\*.com.Outputs set difference: File1.txt - File2.txt. Outputs set intersection: lines present in both files. If the first search term looks like a regex, the search will be a regex one, but if it looks like a plain search term, the whole search will be a plain one even if 2nd or later search terms look like regex. A line is matched if at least one of the search terms matches. A space does not serve to separate two search terms rather, each line is a complete search term. Search for the search terms found in SearchTermsFile.txt, one search term per line. File names in FileList.txt can contain spaces and do not need to be surrounded with quotation marks for this to work. Search in the files stated in FileList.txt, one file per line. The escaping is needed even if the search term is enclosed in quotes. If forward slash ( /) is the 1st character in the search term, it needs to be escaped with a backslash (\). To search for a quote and have the search term enclosed in quotes as well, the enclosing quotes need to be escaped for the shell using caret ( ^).
