intro(1M) intro(1M)NAME intro - introduction to system maintenance commands DESCRIPTION This section describes, in alphabetical order, commands that are used chiefly for system maintenance and administration purposes. The commands in this section should be used along with those listed in Section 1 of the A/UX Command Refer- ence. Cross references in the form name(1M), name(7), or name(8) refer to entries in this manual. Cross references to entries in sections other than 1M, 7 and 8 refer to entries in one of the other A/UX reference manuals (see the Pre- face). REPAIRING DISKS A/UX Local System Administration includes a detailed description of using fsck to repair file systems. It is al- ways a good idea to make a complete backup of a corrupt file system that contains valuable data, just in case the at- tempted repairs result in unnecessary data losses. Choose a backup utility that can copy data from an unmounted file system onto the backup media. To recover from a system crash, refer to Local System Ad- ministration. April, 1990 1
