NAME
sha256sum - compute and check SHA256 message digest
SYNOPSIS
sha256sum
[OPTION] [FILE]...
DESCRIPTION
Print or check SHA256 (256-bit) checksums.
With no FILE, or when FILE is -, read standard input.
-b, --binary
read in binary mode
-c, --check
read SHA256 sums from the FILEs and check them
-t, --text
read 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 formatted checksum lines
--help
display this help and exit
--version
output version information and exit
The sums are computed as described in FIPS-180-2. 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.
