MD5SUM(1) FSF MD5SUM(1)
md5sum - compute and check MD5 message digest
md5sum [OPTION] [FILE]...
md5sum [OPTION] --check [FILE]
Print or check MD5 (128-bit) checksums. With no FILE, or when FILE is -, read standard
read files in binary mode (default on DOS/Windows)
check MD5 sums against given list
read files in text mode (default)
The following two options are useful only when verifying checksums:
don't output anything, status code shows success
warn about improperly formated checksum lines
--help display this help and exit
output version information and exit
The sums are computed as described in RFC 1321. When checking, the input should be a for-
mer output of this program. The default mode is to print a line with checksum, a charac-
ter indicating type (`*' for binary, ` ' for text), and name for each FILE.
