.TP
\fB\-b\fR, \fB\-\-binary\fR
read in binary mode
.TP
\fB\-c\fR, \fB\-\-check\fR
read checksums 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)
.TP
\fB\-z\fR, \fB\-\-zero\fR
end each output line with NUL, not newline,
and disable file name escaping
.SS "The following five options are useful only when verifying checksums:"
.TP
\fB\-\-ignore\-missing\fR
don't fail or report status for missing files
.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

.PP
The sums are computed as described in RFC 3874.
When checking, the input should be a former output of this program.
The default mode is to print a line with: checksum, a space,
a character indicating input mode ('*' for binary, ' ' for text
or where binary is insignificant), and name for each FILE.
.PP
There is no difference between binary mode and text mode on GNU systems.
