5.Sh NAME
6.Nm md5
7.Nd calculate a message-digest fingerprint (checksum) for a file
8.Sh SYNOPSIS
9.Nm md5
10.Op Fl prtx
11.Op Fl s Ar string

13.Sh DESCRIPTION
14.Nm Md5
15takes as input a message of arbitrary length and produces
16as output a 128-bit
17.Dq fingerprint
18or
--- 14 unchanged lines hidden (view full) ---
33sum of each file listed on the command line is printed after the options
34are processed.
35.Bl -tag -width indent
36.It Fl s Ar string
37Print a checksum of the given
38.Ar string .
39.It Fl p
40Echo stdin to stdout and appends the MD5 sum to stdout.
41.It Fl r
42Reverses the format of the output. This helps with visual diffs. Does nothing
