shasum − compute and check SHA1 message digest
sha1sum
[OPTION] [FILE]...
sha1sum [OPTION] --check [FILE]
Print or check
SHA1 (160-bit) checksums. With no FILE, or when FILE is -,
read standard input.
−b, −−binary
read files in binary mode (default on DOS/Windows)
−c, −−check
check SHA1 sums against given list
−t, −−text
read files 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 formated checksum lines
|
−−help |
display this help and exit |
−−version
output version information and exit
The sums are computed as described in FIPS-180-1. 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.
