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)
- --status
- don’t output
anything, status code shows success
- -w, --warn
- warn about improperly formated
checksum lines
- --help
- display this help and exit
- --version

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.
