.SH SYNOPSIS

[\fIOPTION\fR]... [\fIFILE\fR]...
.SH DESCRIPTION
.\" Add any additional description here
.PP
Print or check MD5 (128\-bit) checksums.
With no FILE, or when FILE is \-, read standard input.
.TP
\fB\-b\fR, \fB\-\-binary\fR
read in binary mode
.TP
\fB\-c\fR, \fB\-\-check\fR
read MD5 sums from the FILEs and check them
.TP
\fB\-\-tag\fR
create a BSD\-style checksum
.TP
\fB\-t\fR, \fB\-\-text\fR
read in text mode (default)
.SS "The following four options are useful only when verifying checksums:"
.TP
\fB\-\-quiet\fR
don't print OK for each successfully verified file
.TP
\fB\-\-status\fR
don't output anything, status code shows success
.TP
\fB\-\-strict\fR
exit non\-zero for improperly formatted checksum lines
.TP
\fB\-w\fR, \fB\-\-warn\fR
warn about improperly formatted checksum lines
.TP
\fB\-\-help\fR
display this help and exit
.TP
\fB\-\-version\fR
output version information and exit
.PP
The sums are computed as described in RFC 1321.  When checking, the input
should be a former output of this program.  The default mode is to print
a line with checksum, a character indicating input mode ('*' for binary,
space for text), and name for each FILE.
.SH BUGS
The MD5 algorithm should not be used any more for security related purposes.
Instead, better use an SHA\-2 algorithm, implemented in the programs
sha224sum(1), sha256sum(1), sha384sum(1), sha512sum(1)
