sum(1)sum(1)Namesum - print object file's checksum
Syntaxsum file...
Description
The command calculates and prints a 16-bit checksum for the named file,
and also prints the number of blocks in the file. It is typically used
to look for bad spots, or to validate a file communicated over some
transmission line.
Diagnostics
`Read error' is indistinguishable from end of file on most devices;
check the block count.
