dhcp_relay(1) -- proclaim relay-agent for Dynamic Host Configuration Protocol
|
|
dhcp_relay is the relay-agent that communicates with other DHCP and proclaim clients and servers to provide address-leases across networks using DHCP messages. The format of DHCP messages is based on BOOTP messages (see RFC 951). A detailed protocol specification for DHCP is contained in RFC 1541, available from the Network Information Center. The DHCP relay-agent receives service requests at the UDP port indicated in the bootp service description contained in the file /etc/services (see service... |

diagsetup(1) -- control the contents of the diag user's running of cached and onlinediag
|
|
diagsetup controls the running of cached and onlinediag by the diag user. This command can be used to either turn off the running of these diagnostic tests or to make them run more frequently or less frequently then they do by default. The -x cached | onlinediag parameter indicates which diagnostic testing program we are modifying the behavior of. We can modify the frequency of running one of these programs. The -x parameter must be present for this program to run. The -h par... |

diff(1) -- differential file and directory comparator
|
|
If both arguments are directories, diff sorts the contents of the directories by name, and then runs the regular file diff algorithm (described below) on text files which are different. Binary files which differ (unless -a is specified), common subdirectories, and files which appear in only one directory are listed. Options when comparing directories are: -l long output format; each text file diff is piped through pr(1) to paginate it, other differences are remembered and summarized after all te... |

diff3(1) -- 3-way differential file comparison
|
|
Diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes: ==== all three files differ ====1 file1 is different ====2 file2 is different ====3 file3 is different The type of change suffered in converting a given range of a given file to some other is indicated in one of these ways: f : n1 a Text is to be appended after line number n1 in file f, where f = 1, 2, or 3. f : n1 , n2 c Text is to be changed in the range line n1 to line n2. If n1 = n2, t... |
|
dircmp(1) -- directory comparison
|
|
dircmp examines dir1 and dir2 and generates various tabulated information about the contents of the directories. Listings of files that are unique to each directory are generated for all the options. If no option is entered, a list is output indicating whether the file names common to both directories have the same contents. dircmp processes supplementary code set characters in directory and file names according to the locale specified in the LC_CT... |
|
dirview(1) -- an interactive interface to the contents of a directory or URL
|
|
dirview presents the contents of a directory or URL using the IRIX Interactive Desktop file manager fm. If an fm is already open to that location, its window will be raised. Otherwise, a new fm will be started which will open the directory or URL specified as the pathname argument, and present icons of the items contained in that directory or URL. The icons can be moved, copied, opened, and manipulated in other ways. dirview is a link to fm. See fm(1) for more information, including a descriptio... |
|
dis(1) -- disassemble an object file
|
|
dis disassembles object files into machine instructions. The options are as follows: -b beginaddress disassemble starting at the given address. The address can be in decimal, octal (with a leading 0), or hexadecimal (with a leading 0x). -d section disassemble the named section as data, printing the offset from the beginning of the section. -C demangle C++ names. -D section disassemble the named section as data, printing the actual address of the data. -e endaddress disassembly stops at the given... |

disableXhost(1) -- utility for disabling remote access to local display
|
|
The disableXhost utility is used to prevent remote hosts from placing windows on or otherwise getting access to the local display during a user's login session. All remote hosts will have display access disabled, whether access originally was granted implicitly (ex., using xhost +) or explicitly (ex., using xhost + hostname). Remote toolchests will no longer be able to post windows on the local display; however, remote iconviews (dirviews) will be able to continue displaying and spawning child ... |

dmedia/diskalign(1) -- XLV Aligned Disk Striping Utility
|
|
This utility is designed to assist in creating striped XLV disk volumes for data streaming applications. There are many factors that must be taken into account when creating a striped XLV volume such as stripe alignment, restrictions imposed by a filesystem on the volume and by the operating system I/O functions such as readv(). This tool, in conjunction with diskprep and diskperf will help extract maximum performance from a striped XLV disk configuration for data streaming applications. The out... |
|
sysadm/DiskManager(1) -- view and manager fixed disks
|
|
Managers display information about your system and provide access to interactive guides (also called tasks) that let you administer your system. For example, the User Manager displays a list of the user accounts currently on the system and gives you access to guides like "Add a User Account" and "Modify a User Account." In a Manager window, you can open a guide by choosing its name from the Task menu or by clicking its button at the bottom of the window. The Disk Manager monitors the fixed d... |
|
diskpatch(1) -- prevent stiction problems with some disk drives
|
|
diskpatch is normally run from cron(1M) twice a week and whenever the system is shutdown. It uses the hardware inventory mechanism to find all the disk drives on the system attached to the supported SCSI controllers, (excluding the jag(7M) controller) and determines the type of disk drive by sending the SCSI inquiry command, using the ds(7M) driver. If the drive is found to be one of the susceptible drives, a special command is issued to the drive that causes it to spin down (stop) for a brief p... |
|
dmedia/diskperf(1) -- Disk Performance Testing Utility
|
|
The purpose of this utility is to measure the performance of a disk configuration as either a raw volume or with a filesystem such as XFS. A number of different test patterns are run including forward and backward sequential as well as random seek read/write patterns. The output is tabulated in a form usable for processing by other utilities such as gnuplot for further analysis. |
|
diskusg(1) -- generate disk accounting data by user ID
|
|
diskusg generates intermediate disk accounting information from data in files or the standard input if omitted. diskusg outputs lines on the standard output (one per user) in the following format: uid login #blocks where uid is the numeric user ID of the user login is the login name of the user #blocks is the total number of disk blocks allocated to this user diskusg is normally used to read the inodes of efs or xfs... |

distcp(1) -- copy or compare software distributions
|
|
distcp copies or compares software distributions. Software distributions are software releases for one or more software products prepared by Silicon Graphics and installed by inst(1M) or swmgr(1M). distcp is typically used to copy a software release tape or to copy software from a tape to a server workstation, which becomes the software distribution source for many workstations on a network. NOTE: Installing (loading) the miniroot from tape is no longer possible as of IRIX 6.2. It is still possi... |

dkstat(1) -- report disk I/O statistics
|
|
dkstat reports physical disk I/O statistics. The default report shows the average physical I/O rate (requests per second, or IOPS) to each disk during the sample interval (default 5 seconds). The options to dkstat are as follows; -? Output usage information. -h host Report for the host host, which must be running pmcd(1). The default is to report for the local host. -L Report for the local host and by-pass pmcd(1). This option is mutually exclusive with the -h option and is the default if pmcd(1... |
