NAME

md5sum - compute and check MD5 message digest  

SYNOPSIS

md5sum [OPTION] [FILE]...  

DESCRIPTION

Print or check MD5 (128-bit) checksums. With no FILE, or when FILE is -, read standard input.

-b, --binary
read in binary mode
-c, --check
read MD5 sums from the FILEs and check them
-t, --text
read in text mode (default)
 

The following two options are useful only when verifying checksums:

--status
don't output anything, status code shows success
-w, --warn
warn about improperly formatted checksum lines
--help
display this help and exit
--version
output version information and exit

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 type (`*' for binary, ` ' for text), and name for each FILE.
