Only as many characters as are required to uniquely identify a command need be specified. .Pp The following commands optionally take a .Ar count , which defaults to 1. .Bl -tag -width ".Cm erase" .It Cm weof Write .Ar count end-of-file (EOF) marks at the current position. This returns when the file mark has been written to the media. .It Cm weofi Write .Ar count end-of-file (EOF) marks at the current position. This returns as soon as the command has been validated by the tape drive. .It Cm smk Write .Ar count setmarks at the current position (DDS drives only). .It Cm fsf Forward space .Ar count files. .It Cm fsr Forward space .Ar count records. .It Cm fss Forward space .Ar count setmarks (DDS drives only). .It Cm bsf Backward space .Ar count files. .It Cm bsr Backward space .Ar count records. .It Cm bss Backward space .Ar count setmarks (DDS drives only). .It Cm erase Erase the tape using a long (often very long) method. With a .Ar count of 0, it will erase the tape using a quick method. Operation is not guaranteed if the tape is not at its beginning. The tape will be at its beginning upon completion. .El .Pp The following commands ignore .Ar count . .Bl -tag -width ".Cm geteotmodel" .It Cm rdhpos Read the hardware block position. The block number reported is specific for that hardware only. With drive data compression especially, this position may have more to do with the amount of data sent to the drive than the amount of data written to tape. Some drives do not support this. .It Cm rdspos Read the SCSI logical block position. This typically is greater than the hardware position by the number of end-of-file marks. Some drives do not support this. .It Cm rewind Rewind the tape. .It Cm offline , rewoffl Rewind the tape and place the drive off line. Some drives are never off line. .It Cm load Load the tape into the drive. .It Cm retension Re-tension the tape. This winds the tape from the current position to the end and then to the beginning. This sometimes improves subsequent reading and writing, particularly for streaming drives. Some drives do not support this. .It Cm ostatus Output status information about the drive. For SCSI magnetic tape devices, the current operating modes of density, blocksize, and whether compression is enabled is reported. The current state of the driver (what it thinks that it is doing with the device) is reported. If the driver knows the relative position from BOT (in terms of filemarks and records), it outputs that. Note that this information is not definitive (only BOT, End of Recorded Media, and hardware or SCSI logical block position (if the drive supports such) are considered definitive tape positions). .Pp Also note that this is the old status command, and will be eliminated in favor of the new status command (see below) in a future release. .It Cm errstat Output (and clear) error status information about this device. For every normal operation (e.g., a read or a write) and every control operation (e.g,, a rewind), the driver stores up the last command executed and it is associated status and any residual counts (if any). This command retrieves and outputs this information. If possible, this also clears any latched error information. .It Cm geteotmodel Output the current EOT filemark model. The model states how many filemarks will be written at close if a tape was being written. .It Cm eod , eom Wind the tape to the end of the recorded data, typically after an EOF mark where another file may be written. .It Cm rblim Report the block limits of the tape drive, including the minimum and maximum block size, and the block granularity if any. .El .Pp The following commands may require an .Ar argument . .Bl -tag -width ".Cm seteotmodel" .It Cm sethpos Set the hardware block position. The .Ar argument is a hardware block number to which to position the tape. Some drives do not support this. .It Cm setspos Set the SCSI logical block position. The .Ar argument is a SCSI logical block number to which to position the tape. Some drives do not support this. .It Cm blocksize Set the block size for the drive. The .Ar argument is the number of bytes per block, except 0 commands the drive to use variable-length blocks. .It Cm seteotmodel Set the EOT filemark model to .Ar argument and output the old and new models. Typically this will be 2 filemarks, but some devices (typically QIC cartridge drives) can only write 1 filemark. You may only choose a value of .Ar 1 or .Ar 2 . .It Cm status Output status information about the drive. For SCSI magnetic tape devices, the current operating modes of density, blocksize, and whether compression is enabled is reported. The current state of the driver (what it thinks that it is doing with the device) is reported. .Pp If the driver knows the relative position from BOT (in terms of filemarks and records), it outputs that. If the tape drive supports the long form report of the .Tn SCSI READ POSITION command, the Reported File Number and Reported Record Number will be numbers other than -1, and there may be Flags reported as well. .Pp The BOP flag means that the logical position of the drive is at the beginning of the partition. .Pp The EOP flag means that the logical position of the drive is between Early Warning and End of Partition. .Pp The BPEW flag means that the logical position of the drive is in a Programmable Early Warning Zone or on the EOP side of Early Warning. .Pp Note that the Reported Record Number is the tape block or object number relative to the beginning of the partition. The Calculated Record Number is the tape block or object number relative to the previous file mark. .Pp Note that the Calculated File and Record Numbers are not definitive. The Reported File and Record Numbers are definitive, if they are numbers other than -1. .Bl -tag -width 6n .It Fl v Print additional status information, such as the maximum supported I/O size. .It Fl x Print all available status data to stdout in XML format. .El .It Cm getdensity Report density support information for the tape drive and any media that is loaded. Most drives will report at least basic density information similar to that reported by .Nm status command. Newer tape drives that conform to the T-10 SSC and newer tape specifications may report more detailed information about the types of tapes they support and the tape currently in the drive. .Bl -tag -width 6n .It Fl x Print all available density data to stdout in XML format. Because density information is currently included in the general status XML report used for .Nm status command, this will be the same XML output via .Do .Nm status -.Fl x +.Fl x .Dc .El .It Cm param Display or set parameters. -One of +One of .Fl l , .Fl s , or .Fl x must be specified to indicate which operation to perform. .Bl -tag -width 8n .It Fl l List parameters, values and descriptions. By default all parameters will be displayed. To display a specific parameter, specify the parameter with .Fl p . .It Fl p Ar name Specify the parameter name to list (with .Fl l ) -or set (with +or set (with .Fl s ) . .It Fl q Enable quiet mode for parameter listing. This will suppress printing of parameter descriptions. .It Fl s Ar value Specify the parameter value to set. The general type of this argument (integer, unsigned integer, string) is determined by the type of the variable indicated by the .Xr sa 4 driver. More detailed argument checking is done by the .Xr sa 4 driver. .It Fl x Print out all parameter information in XML format. .El .It Cm protect Display or set drive protection parameters. This is used to control checking and reporting a per-block checksum for tape drives that support it. Some drives may only support some parameters. .Bl -tag -width 8n .It Fl b Ar 0|1 Set the Recover Buffered Data Protected bit. If set, this indicates that checksums are transferred with the logical blocks transferred by the RECOVERED BUFFERED DATA .Tn SCSI command. .It Fl d Disable all protection information settings. .It Fl e Enable all protection information settings. The default protection method used is Reed-Solomon CRC (protection method 1), as specified in ECMA-319. The default protection information length used with Reed-Solomon CRC is 4 bytes. To enable all settings except one more more settings, specify the .Fl e argument and then explicitly disable settings that you do not wish to enable. For example, specifying .Fl e .Fl w Ar 0 will enable all settings except for LBP_W. .It Fl l List available protection parmeters and their current settings. .It Fl L Ar len Set the length of the protection information in bytes. For Reed-Solomon CRC, the protection information length should be 4 bytes. .It Fl m Ar num Specify the numeric value for the protection method. The numeric value for Reed-Solomon CRC is 1. .It Fl r Ar 0|1 Set the LBP_R parameter. When set, this indicates that each block read from the tape drive will have a checksum at the end. .It Fl v Enable verbose mode for parameter listing. This will include descriptions of each parameter. .It Fl w Ar 0|1 Set the LBP_W parameter. When set, this indicates that each block written to the tape drive will have a checksum at the end. The drive will verify the checksum before writing the block to tape. .El .It Cm locate Set the tape drive's logical position. -One of +One of .Fl b , .Fl e , .Fl f , -or +or .Fl s must be specified to indicate the type of position. If the partition number is specified, the drive will first relocate to the given partition (if it exists) and then to the position indicated within that partition. If the partition number is not specified, the drive will relocate to the given position within the current partition. .Bl -tag -width 14n .It Fl b Ar block_addr Relocate to the given tape block or logical object identifier. Note that the block number is the Reported Record Number that is relative to the beginning of the partition (or beginning of tape). .It Fl e Relocate to the end of data. .It Fl f Ar fileno Relocate to the given file number. .It Fl p Ar partition Specify the partition to change to. .It Fl s Ar setmark Relocate to the given set mark. .El .It Cm comp Set the drive's compression mode. The non-numeric values of .Ar argument are: .Pp .Bl -tag -width 9n -compact .It off Turn compression off. .It on Turn compression on. .It none Same as .Ar off . .It enable Same as .Ar on . .It IDRC IBM Improved Data Recording Capability compression (0x10). .It DCLZ DCLZ compression algorithm (0x20). .El .Pp In addition to the above recognized compression keywords, the user can supply a numeric compression algorithm for the drive to use. In most cases, simply turning the compression .Sq on will have the desired effect of enabling the default compression algorithm supported by the drive. If this is not the case (see the .Cm status display to see which compression algorithm is currently in use), the user can manually specify one of the supported compression keywords (above), or supply a numeric compression value from the drive's specifications. .Pp Note that for some older tape drives (for example the Exabyte 8200 and 8500 series drives) it is necessary to switch to a different density to tell the drive to record data in its compressed format. If the user attempts to turn compression on while the uncompressed density is selected, the drive will return an error. This is generally not an issue for modern tape drives. .It Cm density Set the density for the drive. For the density codes, see below. The density value could be given either numerically, or as a string, corresponding to the .Dq Reference field. If the string is abbreviated, it will be resolved in the order shown in the table, and the first matching entry will be used. If the given string and the resulting canonical density name do not match exactly, an informational message is output about what the given string has been taken for. .El .Pp The initial version of the density table below was taken from the .Sq Historical sequential access density codes table (A-1) in Revision 11 of the SCSI-3 Stream Device Commands (SSC) working draft, dated November 11, 1997. Subsequent additions have come from a number of sources. .Pp The density codes are: .Bd -literal -offset 2n 0x0 default for device 0xE reserved for ECMA Value Width Tracks Density Code Type Reference Note mm in bpmm bpi 0x01 12.7 (0.5) 9 32 (800) NRZI R X3.22-1983 2 0x02 12.7 (0.5) 9 63 (1,600) PE R X3.39-1986 2 0x03 12.7 (0.5) 9 246 (6,250) GCR R X3.54-1986 2 0x05 6.3 (0.25) 4/9 315 (8,000) GCR C X3.136-1986 1 0x06 12.7 (0.5) 9 126 (3,200) PE R X3.157-1987 2 0x07 6.3 (0.25) 4 252 (6,400) IMFM C X3.116-1986 1 0x08 3.81 (0.15) 4 315 (8,000) GCR CS X3.158-1987 1 0x09 12.7 (0.5) 18 1,491 (37,871) GCR C X3.180 2 0x0A 12.7 (0.5) 22 262 (6,667) MFM C X3B5/86-199 1 0x0B 6.3 (0.25) 4 63 (1,600) PE C X3.56-1986 1 0x0C 12.7 (0.5) 24 500 (12,690) GCR C HI-TC1 1,6 0x0D 12.7 (0.5) 24 999 (25,380) GCR C HI-TC2 1,6 0x0F 6.3 (0.25) 15 394 (10,000) GCR C QIC-120 1,6 0x10 6.3 (0.25) 18 394 (10,000) GCR C QIC-150 1,6 0x11 6.3 (0.25) 26 630 (16,000) GCR C QIC-320 1,6 0x12 6.3 (0.25) 30 2,034 (51,667) RLL C QIC-1350 1,6 0x13 3.81 (0.15) 1 2,400 (61,000) DDS CS X3B5/88-185A 5 0x14 8.0 (0.315) 1 1,703 (43,245) RLL CS X3.202-1991 5,11 0x15 8.0 (0.315) 1 1,789 (45,434) RLL CS ECMA TC17 5,12 0x16 12.7 (0.5) 48 394 (10,000) MFM C X3.193-1990 1 0x17 12.7 (0.5) 48 1,673 (42,500) MFM C X3B5/91-174 1 0x18 12.7 (0.5) 112 1,673 (42,500) MFM C X3B5/92-50 1 0x19 12.7 (0.5) 128 2,460 (62,500) RLL C DLTapeIII 6,7 0x1A 12.7 (0.5) 128 3,214 (81,633) RLL C DLTapeIV(20) 6,7 0x1B 12.7 (0.5) 208 3,383 (85,937) RLL C DLTapeIV(35) 6,7 0x1C 6.3 (0.25) 34 1,654 (42,000) MFM C QIC-385M 1,6 0x1D 6.3 (0.25) 32 1,512 (38,400) GCR C QIC-410M 1,6 0x1E 6.3 (0.25) 30 1,385 (36,000) GCR C QIC-1000C 1,6 0x1F 6.3 (0.25) 30 2,666 (67,733) RLL C QIC-2100C 1,6 0x20 6.3 (0.25) 144 2,666 (67,733) RLL C QIC-6GB(M) 1,6 0x21 6.3 (0.25) 144 2,666 (67,733) RLL C QIC-20GB(C) 1,6 0x22 6.3 (0.25) 42 1,600 (40,640) GCR C QIC-2GB(C) ? 0x23 6.3 (0.25) 38 2,666 (67,733) RLL C QIC-875M ? 0x24 3.81 (0.15) 1 2,400 (61,000) CS DDS-2 5 0x25 3.81 (0.15) 1 3,816 (97,000) CS DDS-3 5 0x26 3.81 (0.15) 1 3,816 (97,000) CS DDS-4 5 0x27 8.0 (0.315) 1 3,056 (77,611) RLL CS Mammoth 5 0x28 12.7 (0.5) 36 1,491 (37,871) GCR C X3.224 1 0x29 12.7 (0.5) 0x2A 0x2B 12.7 (0.5) 3 ? ? ?

It may be overridden with the .Fl f option. .El .Sh FILES .Bl -tag -width ".Pa /dev/*sa[0-9]*" -compact .It Pa /dev/*sa[0-9]* SCSI magnetic tape interface .El .Sh DIAGNOSTICS The exit status will be 0 when the drive operations were successful, 2 when the drive operations were unsuccessful, and 1 for other problems like an unrecognized command or a missing drive device. .Sh COMPATIBILITY Some undocumented commands support old software. .Sh SEE ALSO .Xr dd 1 , .Xr ioctl 2 , .Xr mtio 4 , .Xr sa 4 , .Xr environ 7 .Sh HISTORY The .Nm command appeared in .Bx 4.3 . .Pp Extensions regarding the .Xr st 4 driver appeared in .Bx 386 0.1 as a separate .Nm st command, and have been merged into the .Nm command in .Fx 2.1 . .Pp The former .Cm eof command that used to be a synonym for .Cm weof has been abandoned in .Fx 2.1 since it was often confused with .Cm eom , which is fairly dangerous. .Sh BUGS The utility cannot be interrupted or killed during a long erase (which can be longer than an hour), and it is easy to forget that the default erase is long. .Pp Hardware block numbers do not always correspond to blocks on the tape when the drive uses internal compression. .Pp Erasure is not guaranteed if the tape is not at its beginning. .Pp Tape-related documentation is poor, here and elsewhere.

The .Nm b64encode utility is synonymous with .Nm with the .Fl m flag specified. The .Nm b64decode utility is synonymous with .Nm uudecode with the .Fl m flag specified. .Pp The .Nm utility reads .Ar file (or by default the standard input) and writes an encoded version to the standard output, or .Ar output_file if one has been specified. The encoding uses only printing .Tn ASCII characters and includes the mode of the file and the operand .Ar name for use by .Nm uudecode . .Pp The .Nm uudecode utility transforms .Em uuencoded files (or by default, the standard input) into the original form. The resulting file is named either .Ar name or (depending on options passed to .Nm uudecode ) .Ar output_file and will have the mode of the original file except that setuid and execute bits are not retained. The .Nm uudecode utility ignores any leading and trailing lines. .Pp The following options are available for .Nm : .Bl -tag -width ident .It Fl m Use the Base64 method of encoding, rather than the traditional .Nm algorithm. .It Fl r Produce raw output by excluding the initial and final framing lines. .It Fl o Ar output_file Output to .Ar output_file instead of standard output. .El .Pp The following options are available for .Nm uudecode : .Bl -tag -width ident .It Fl c Decode more than one uuencoded file from .Ar file if possible. .It Fl i Do not overwrite files. .It Fl m When used with the .Fl r flag, decode Base64 input instead of traditional .Nm input. Without .Fl r it has no effect. .It Fl o Ar output_file Output to .Ar output_file instead of any pathname contained in the input data. .It Fl p Decode .Ar file and write output to standard output. .It Fl r Decode raw (or broken) input, which is missing the initial and possibly the final framing lines. The input is assumed to be in the traditional .Nm encoding, but if the .Fl m flag is used, or if the utility is invoked as .Nm b64decode , then the input is assumed to be in Base64 format. .It Fl s Do not strip output pathname to base filename. By default .Nm uudecode deletes any prefix ending with the last slash '/' for security reasons. .El .Sh EXAMPLES The following example packages up a source tree, compresses it, uuencodes it and mails it to a user on another system. When .Nm uudecode is run on the target system, the file ``src_tree.tar.Z'' will be created which may then be uncompressed and extracted into the original tree. .Pp .Bd -literal -offset indent -compact tar cf \- src_tree \&| compress \&| uuencode src_tree.tar.Z \&| mail user@example.com .Ed .Pp The following example unpacks all uuencoded files from your mailbox into your current working directory. .Pp .Bd -literal -offset indent -compact uudecode -c < $MAIL .Ed .Pp The following example extracts a compressed tar archive from your mailbox .Pp .Bd -literal -offset indent -compact uudecode -o /dev/stdout < $MAIL | zcat | tar xfv - .Ed .Sh SEE ALSO .Xr basename 1 , .Xr compress 1 , .Xr mail 1 , .Xr uucp 1 Pq Pa ports/net/freebsd-uucp , .Xr uuencode 5 .Sh HISTORY The .Nm uudecode and .Nm utilities appeared in .Bx 4.0 . .Sh BUGS Files encoded using the traditional algorithm are expanded by 35% (3 bytes become 4 plus control information).
