|---|
| 20 | .PP | 
|---|
| 21 | The checksum of each argument is computed and printed, along with the file | 
|---|
| 22 | length and its name, one file per line. | 
|---|
| 23 | This program is useful for seeing if a file transmitted to another machine | 
|---|
| 24 | has arrived correctly. | 
|---|
| 25 | It is conceptually similar to \fIsum\fR, except that it uses a stronger | 
|---|
| 26 | checksum algorithm and also prints the length. | 
|---|
| 27 | .SH "SEE ALSO" | 
|---|
| 28 | .BR cksum (1), |

| 29 | .BR sum (1). |
