How do I search files for a batch-file or command-line string?
January 8, 2000
A. The find command lets you search one file at a time for a string, but the findstr command is more versatile. This command has the following switches.
findstr [/b] [/e] [/l] [/r] [/s] [/i] [/x] [/v] [/n] [/m] [/o] [/f:file] [/c:string] [/g:file] [strings] [[drive:][path]filename[ ...]]
The following table explains each parameter.
Parameters | Meaning |
---|---|
/b | Matches pattern if at the start of a line |
/e | Matches pattern if at the end of a line |
/l | Searches literally |
/r | Uses text as a regular expression (default) |
/s | Searches current directory and all subdirectories |
/i | Ignores case |
/x | Selects lines that are an exact match |
/v | Selects lines that don’t match |
/n | Displays the line number before the matched line |
/m | Displays only the matching filenames |
/o | Displays the offset of the match before the matched line |
/g: | Gets the search string from the specified file (e.g., /g:argument.txt) |
/c:"" | Uses text as a literal (e.g., /c:"string") |
/f: | Gets the file list from the specified file (e.g., /f:filelist.txt) |
strings | Denotes the search string (in double quotes if multiple words) |
files | Shows the files to search |
Use spaces to separate multiple search strings unless you use /c.
The command
findstr "Windows NT FAQ" ntfaq.html
would search for Windows, NT, or FAQ in ntfaq.html. The command
findstr /c:"Windows NT FAQ" ntfaq.html
would search for Windows NT FAQ in ntfaq.htm.
