SYNOPSIS

9       md5sum [OPTION] [FILE]...
10

DESCRIPTION

12       Print  or check MD5 (128-bit) checksums.  With no FILE, or when FILE is
13       -, read standard input.
14
15       -b, --binary
16              read in binary mode
17
18       -c, --check
19              read MD5 sums from the FILEs and check them
20
21       -t, --text
22              read in text mode (default)
23
24   The following two options are useful only when verifying checksums:
25       --status
26              don't output anything, status code shows success
27
28       -w, --warn
29              warn about improperly formatted checksum lines
30
31       --help display this help and exit
32
33       --version
34              output version information and exit
35
36       The sums are computed as described in RFC  1321.   When  checking,  the
37       input  should  be a former output of this program.  The default mode is
38       to print a line with checksum, a character  indicating  type  (`*'  for
39       binary, ` ' for text), and name for each FILE.
