15 | .SH DESCRIPTION |
| 16 | .I Rc | |
| 2951b510 KM |
17 | is the command script which controls the automatic reboot and |
| 18 | .I rc.local | |
| 19 | is the script holding commands which are pertinent only | |
| 20 | to a specific site. | |

21 | .PP |
| 22 | When an automatic reboot is in progress, | |
| 23 | .I rc | |
| 24 | is invoked with the argument | |
| 25 | .I autoboot | |
| 26 | and runs a | |
| 27 | .I fsck | |
| 28 | with option | |
| 29 | .B \-p | |
| 30 | to ``preen'' all the disks of minor inconsistencies resulting | |
| 31 | from the last system shutdown and to check for serious inconsistencies | |
| 32 | caused by hardware or software failure. | |
| 33 | If this auto-check and repair succeeds, then the second part of | |
| 34 | .I rc | |
| 35 | is run. | |
| 36 | .PP | |
| 37 | The second part of | |
| 38 | .I rc, | |
| 39 | which is run after a auto-reboot succeeds and also if | |
| 40 | .I rc | |
| 41 | is invoked when a single user shell terminates (see | |
| 42 | .IR init (8)), | |
| 43 | starts all the daemons on the system, preserves editor files | |
| 44 | and clears the scratch directory | |
| 45 | .B /tmp. | |
| 2951b510 KM |
46 | .I Rc.local |
| 47 | is executed immediately before any other commands after a successful | |
| 48 | .IR fsck . | |
| 49 | Normally, the first commands placed in the | |
| 50 | .I rc.local | |
| 51 | file define the machine's name, using | |
| 52 | .IR hostname (1), | |
| 53 | and save any possible core image that might have been | |
| 54 | generated as a result of a system crash, | |
| 55 | .IR savecore (8). | |
| 56 | The latter command is included in the | |
| 57 | .I rc.local | |
| 58 | file because the directory in which core dumps are saved | |
| 59 | is usually site specific. | |
