NAME
sha1sum - compute and check SHA1 message digest

SYNOPSIS
sha1sum [OPTION]... [FILE]...

DESCRIPTION
Print or check SHA1 (160-bit) checksums. With no FILE, or when FILE is
-, read standard input.

-b, --binary
read in binary mode

-c, --check
read SHA1 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

--strict
with --check, exit non-zero for any invalid input

--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.
