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 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-180-1. 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.
