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 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
- --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.
