md5sum... = 1d1784b018c2d8f82b41db81c1db62cb
Usage: md5sum [OPTION]... [FILE]...
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 three options are useful only when verifying checksums:
--quiet don't print OK for each successfully verified file
--status don't output anything, status code shows success
-w, --warn warn about improperly formatted checksum lines
--strict with --check, exit non-zero for any invalid input
--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.
