NAME
        shasum - compute and check SHA1 message digest
 
SYNOPSIS
        sha1sum [OPTION] [FILE]...
        sha1sum [OPTION] --check [FILE]
 
DESCRIPTION
        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 pro­
        gram.   The default mode is to print a line with checksum,
        a character indicating type  (`*'  for  binary,  `  '  for
        text), and name for each FILE.
