- This manual page documents the GNU version of ssssuuuummmm. ssssuuuummmm com-
- putes a 16-bit checksum for each named file, or the standard
- input if none are given or when a file named `-' is given.
- It prints the checksum for each file along with the number
- of blocks in the file (rounded up). By default each
- corresponding file name is also printed if at least two
- arguments are specified. With the - - _s_y_s_v option,
- corresponding file name are printed when there is at least
- one file argument. By default, the GNU ssssuuuummmm computes check-
- sums using an algorithm that is compatible with the BSD ssssuuuummmm
- and prints file sizes in units of 1K blocks.
-
- OOOOPPPPTTTTIIIIOOOONNNNSSSS
- -_r Use the default (BSD compatible) algorithm. This
- option is included for compatibility with the System V
- ssssuuuummmm. Unless the -_s option was also given, it has no
- effect.
-
- -_s, --_s_y_s_v
- Compute checksums using an algorithm that is compatible
- with the one the System V ssssuuuummmm uses by default and print
- file sizes in units of 512-byte blocks instead of 1K.
-
- --_h_e_l_p
- Print a usage message and exit with a non-zero status.
-
- --_v_e_r_s_i_o_n
- Print version information on standard output then exit.
