findstr is a shell command that searches for text in files[1] and prints matching lines to standard output.[2] The command provides similar functionality as find, but findstr supports some regular expression operators. However, findstr does not support UTF-16 whereas find does. findstr cannot search for null bytes commonly found in Unicode computer files.[3]

findstr was first released as part of the Windows 2000 Resource Kit under the name qgrep.[4] The command is available in Windows[5][6] and ReactOS.[7]
