| 14 | * cptime.c Version 1.4 |
---|
| 15 | * |
---|
| 16 | * Timed copy; read entire file then output total time, bytes transferred, |
---|
| 17 | * and compute transfer rate. |
---|
| 18 | * |
---|
| 19 | * cptime [-s|-l] [-v|-q] [-b _SIZE_] [-n _LEN_] _FILE_... |
---|
| 20 | * -s Change to simple output mode without computing transfer rate |
---|
| 21 | * -l Change to long output mode (to allow for overriding previous -s) |
---|
| 22 | * -v Verbose output |
---|
| 23 | * -q Quiet output |
---|
| 24 | * -b _SIZE_ use _SIZE_ for transfer size |
---|
| 25 | * -n _LEN_ maximum length to fetch |
---|
| 26 | * _FILE_... Space delimited list of files to dump |
---|
| 27 | * Note: The last instance of -s or -l wins, along with the last use of -b and -n and the winning option will be applied to all operations |
---|
| 28 | * |
---|
| 29 | * Hisory: |
---|
| 30 | * 1.4 Use fread() rather than read(); use CLK_TCK when available. |
---|
| 31 | * 1.3 Added -v/-q; rework some argument processing. |
---|
| 32 | * 1.2 Added -n |
---|
| 33 | * 1.1 Added -l and -b switches; more flexible command line processing |
---|
| 34 | * 1.0 First release |
