INTRO(8) BSD System Manager's Manual INTRO(8)
NAME
intro -- introduction to system maintenance and operation commands
DESCRIPTION
This section contains information related to system operation and maintenance. It describes commands
used to create new file systems, newfs(8), verify the integrity of the file systems, fsck(8), control
disk usage, edquota(8), maintain system backups, dump(8), and recover files when disks die an untimely
death, restore(8).
All commands set an exit status. Its value may be tested to see if the command completed normally.
Unless otherwise noted (rare), the value 0 signifies successful completion of the command, while a
value >0 indicates an error. Some commands attempt to describe the nature of the failure by using
error codes defined in sysexits(3), or set the status to arbitrary values >0 (typically 1), but many
such values are not described in the manual.
HISTORY
The intro section manual page appeared in 4.2BSD.
