NAME

md5sum - compute and check MD5 message digest

SYNOPSIS

md5sum [OPTION] [FILE]...

md5sum [OPTION] --check [FILE]

DESCRIPTION

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

-b, --binary

read files in binary mode (default on DOS/Windows)

-c, --check

check MD5 sums against given list

-t, --text

read files 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 formated 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.
