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
- create a BSD-style checksum
- -t, --text
- read in text mode (default)
- -z, --zero
- end each output line with NUL, not newline, and disable file name escaping
- don't fail or report status for missing files
- don't print OK for each successfully verified file
- don't output anything, status code shows success
- exit non-zero for improperly formatted checksum lines
- -w, --warn
- warn about improperly formatted checksum lines
- 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 former output of this program. The default mode is to print a line with checksum, a space, a character indicating input mode ('*' for binary, ' ' for text or where binary is insignificant), and name for each FILE.
Note: There is no difference between binary mode and text mode on GNU systems.
