In particular, commands used to create new file systems, .IR newfs , .IR mkfs , and verify the integrity of the file systems, .IR fsck , .IR icheck , .IR dcheck , and .I ncheck are described here. The section .I format shold be consulted when formatting disk packs. The section .I crash should be consulted in understanding how to interpret system crash dumps. .PP .ti +1.0i \fIMaintenance and System Operation Commands\fP .PP .ta 1.25i .nf MAKEDEV make system special files ac login accounting adduser procedure for adding new users analyze virtual memory postmortem crash analyzer arcv convert an old archive to the new format arff archiver for 11/780 console floppies and 11/730 console cassettes bad144 read/write dec standard 144 bad sector information badsect program for dealing with bad sectors on disks catman create the cat'able files for the manual chown change owner clri clear i-node comsat mail notification server config build system configuration files crash what happens when the system crashes cron clock daemon dcheck file system directory consistency check diskpart disk partition calculator dmesg collect system diagnostic messages to form error log dump incremental file system dump dumpfs dump file system information fastboot reboot a system without checking any file systems flcopy copy 11/780 console floppies format standalone disk formatting program and procedures fsck file system consistency check and interactive repair ftpd DARPA file transfer protocol server gettable obtain network database file from a remote host getty set terminal mode halt stop the processor icheck file system storage consistency check implogd IMP logging server init process control initialization kgmon control system profiling lpd line printer daemon makekey generate encryption key mkfs construct a file system mknod build special file mkproto construct a pototype file system mount, umount mount and dismount file system ncheck generate names from i-numbers newfs build a new file system pstat print system facts quot summarize file system ownership rc command script for auto-reboot and daemons reboot UNIX bootstrapping procedures renice alter priority of running process by changing nice restor incremental file system restore rexecd remote execution (with password authentication) server rlogind remote login server rmt remote magtape access protocol interpreter route manually manipulate network routing tables routed network routing daemon rrestor remote file system restore facility rshd remote execution (without password authentication) server rwhod system status server sa, accton system accounting savecore save a core dump of the operating system sendmail send mail over the internet shutdown close down the system at a given time sticky executable files with persistent text swapon specify additional device for paging and swapping sync update the super block telnetd TELNET protocol server tftpd TFTP server trpt TCP protocol trace analyzer tunefs tune the parameters of an existing file system update periodically update the super block vipw edit the password file with vi vpac print raster printer/ploter accounting information .fi
