Simple MD5

Windows command line utility for viewing, generating and verifying MD5 hashes of files.

Usage:

md5.exe [file1[+file2][+file3]...] [/r] [[/w [path]] | [/v [path]]] [/f] [[/x pattern]...]

File name arguments may point to either a file or a directory. When pointing to a directory, all files in the directory will be processed.

Wildcards can be used for file name arguments, which will be evaluated against the contents of the current directory.

If no file name arguments are provided, all files in the current directory will be scanned.

Note: File names ending with .md5 are always ignored for write or verify operations

Options

Switch	Description
/r	Scan directories recursively
/w <path>	Write the hash into <filename>.md5. If path is specified, file will be written to specified location instead of alongside source file. Cannot be used with /v
/v <path>	Verify hashes. If path is specified, hash will be read from specified location. Cannot be used with /w
/f	Show full paths
/e	Show errors only (only applicable with /v)
/n	Write hash information for new files only (only applicable with /w)
/x <pattern>	Excludes files or directories based on a pattern. May be specified multiple times. Directory separators must be Unix style, e.g. /.

Exit Codes

Code	Description
0	Success
1	Failed
2	Verify Failed
