t-act command The t-act command selects a previously attached tape device as the currently active device to read and write to. D3 releases not only can have many users using many tapes simultaneously, a single user can have multiple tapes. This command allows switching between tapes.
t-att command The t-att command attaches the tape unit or floppy disk drive to the current process unit and optionally assigns the block size to the tape I/O buffer.
t-bck command The t-bck command backspaces the tape to the end of the previous file or a specified number of blocks.
t-bsf command The t-bsf command backspaces a given number of files.
t-bsr command The t-bsr command backspaces a given number of records.
t-cascade command The t-cascade command cascades or links one tape device to another tape device, either in a chain or a loop. Instead of prompting for the next reel, the system uses the forwardly linked device specified. Tape attachment is not checked. This command updates the links of the tape devices.
t-chk command The t-chk command checks a tape for parity errors. At the end of the process, the number of files checked displays.
t-copy command The t-copy BASIC program copies data from one device to another.
t-det command The t-det command detaches the tape from the current process, or from another process. If no device number is specified, then all tape devices currently attached to this process are detached.
t-dump command The t-dump command copies items from a given file to the attached peripheral storage device. The heading modifier allows specifying the contents of the tape label written to the tape prior to the dump. The tape must already be at load point in order to write the tape label.
t-fsf command The t-fsf (forward space file) command forwards a tape a given number of files. If the number is omitted, this command behaves like a t-fwd command.
t-fsr command The t-fsr (forward space record) command forwards a tape a given number of records. If the number is omitted, this command behaves like a t-fwd command.
t-fwd command The t-fwd command moves the attached media forward to the next file, or moves the tape forward a specified number of blocks. The t-fwd command stops automatically at an EOF.
t-link command The t-link command links or cascades one tape device to another tape device, either in a chain or a loop. Instead of prompting for the next reel, the system uses the forwardly linked device specified. Tape attachment is not checked. This command updates the links of the tape devices.
t-load command The t-load command restores files from a tape that was generated by t-dump. If a selection criteria is not specified, the entire file is loaded. If multiple t-dump commands were performed, then multiple executions of t-load are required to restore the data.
t-rdlbl command The t-rdlbl command reads the label from the attached magnetic media and initializes the internal label storage area.
t-read command The t-read command reads from the magnetic media unit attached to the current process and displays the contents of each block read to the terminal or printer. Any type of Pick-formatted media may be read with this command.
t-rew command The t-rew command rewinds the attached media to the beginning, or load point on the tape.
t-select command The t-select command attaches a tape device to the current process, but we recommend using the set-device TCL command.
t-space command The t-space command moves the attached media forward a specified number of files, displaying each tape label as it is encountered.
t-stat command The t-stat command displays a report of the current attachment status for all tape devices defined on the system. It shows the device number and description, UNIX process name, density, and currently attached user.
t-unload command The t-unload command rewinds the attached tape. On D3 UNIX systems, this command does the usual tape unload. Depending on the UNIX operating system, this command may wait for the tape to rewind before returning.
t-verify command The t-verify command validates the integrity of file-save or account-save backups. The process can compare the contents of the backup media with the corresponding data on disk, or check the media to ensure that it has the correct backup format.
t-weof command The t-weof command writes an EOF mark at the current position on the attached magnetic media. It also causes a flush of the last buffer written. This is important to ensure any partially filled buffer was written onto the tape.
t-wtlbl command The t-wtlbl command writes a Pick-format (80-byte) tape label at the current position on the attached magnetic media.
tabs command The tabs command displays tab stops previously set via the editor (ed or edit) process, or assigns new tab stop positions for input (i) or output (o).
tail command The tail command displays a specified number of trailing lines for each of the items in a specified item-list (that is, the bottom-most lines contained in an item).
tandem command The tandem BASIC program links the current port to another process. Any input or output to either screen affects both screens.
tape-socket command The tape-socket BASIC program defines a tape system across a network.
tcl command The tcl command suspends the process on the specified port, pushes a level on that port, then executes the TCL command.
tcl-hdr command The tcl-hdr command enables or disables the display of TCL commands on all output directed to the spooler, or displays the current header status if no options are provided.
tcl-prompt command The tcl-prompt BASIC program sets the prefix to the TCL prompt.
tcls command The tcls command suspends the process on the specified port, pushes a level on that port, then executes the TCL command. This is different from the tcl command in that tcls suppresses the messages generated by the command that was executed on the remote port.
term command The term BASIC program changes or displays the current terminal and printer output characteristics for the current line.
term.font command The term.font BASIC program downloads fonts to a Wyse 60 terminal. It uses a special file, which has 8x16 matrixes for every character in hexadecimal format.
term-type command The term-type BASIC program reads the terminal and printer characteristics from attribute 2 of the PIBs file and automatically sets them, or sets them and updates the permanent settings for the current line.
termp command The termp BASIC program is an interactive form of the term command. It prompts for the terminal and printer characteristics for the line on which the command is invoked.
termu command The termu BASIC program automatically updates the term width and depth. This is done by reading the values from the Unix stty command. termu is the default value for the sigwinch signal of the trap command.
time command The time BASIC program displays the system time and date. If no time parameter exists, the current time and date displays.
timedate command The timedate command sets or displays the status of the time and date display.
timeout command The timeout BASIC program sets the time (in seconds) to automatically log off due to inactivity. If no time out value is provided, then the current value displays. A time out value of 0 disables the timeout. This state is the default. If the line sits at an input for the time-out period, the command specified in the trap functionality is executed. The default is to log off.
tlog-restore command The tlog-restore command restores data from a transaction log magnetic media. This is an alternative to restoring at the end of a full restore or account restore from a ’save-class’ media.
tlqdisplay command The tlqdisplay command allows you to display the transactions within the transaction queue used by both the D3 Transaction Logger and Hot Backup components. The start location in the transaction queue can be specified.
touch command The touch BASIC program reads and rewrites all items, without changing them, in either specified files or in all files in specified accounts.
transaction utility The transaction utility is the system administration utility for transaction processing.
trap command The trap BASIC program allows a TCL command (signal handler) to be executed upon receiving a specific signal.
truncate-ovf command The truncate-ovf command truncates the safe overflow table to 1 block from high-water to maxfid and kills the B-tree table.
txlog command The txlog BASIC program invokes a menu for administration of the transaction logging subsystem.
txlog-off command The txlog-off command turns off transaction log enqueueing for the current process. No matter what operation is done by the user, a transaction will not be placed in the queue for later dequeuing to the tape or hot backup machine.
txlog-on command The txlog-on command turns on transaction log enqueueing for the current process.
txlog-status command The txlog-status command retrieves the last status of the transaction logging subsystem.
type-ahead command The type-ahead command enables or disables the type ahead feature for the current PIB, or displays the current status if no options are provided.
