Short: Copy block devices and streams/files Author: Christian E. Hopps, Roc Vallès Domènech Uploader: polluks+aminet sdf lonestar org (Stefan Haubenthal) Type: disk/misc Version: 2.0.0 Architecture: generic # device-streams Amiga tool for copying between block devices and streams/files, similar to UNIX `dd`. Originally released by Christian E. Hopps in 1993, updated to be useful today. Requires AmigaOS 2.04+. ## Usage Run the command with `-h` parameter to display usage information. ### Examples #### Print RDB device and partition information. ``` 5.Ram Disk:> devstreams/rdbinfo Device: "scsi.device" Unit: 0 Capacity: 114473.4 Megs DiskVendor: FUJITSU DiskProduct MHV2120AH DiskRevision: 0000 Cylinders: 232581 Heads: 16 Blks-p-Trk: 63 [Blks-p-Cyl: 1008] Total Blocks: 234441648 Block Size 512 64bit --| Partition: "DH0" Capacity: 1023.7 Megs --| Start Block: 3024 End Block: 2099663 Total Blocks: 2096640 --| Block Size: 512 --| Partition: "DH1" Capacity: 10239.4 Megs --| Start Block: 2099664 End Block: 23070095 Total Blocks: 20970432 --| Block Size: 512 --| 64bit ### ``` #### Dump a partition into a file. ``` 5.Ram Disk:> devstreams/devtostream --output=DH1:dump.dd --rdb-name=DH0 --verbose found new device "scsi.device" found drive FUJITSU MHV2120AH 0000 [capacity:114473M] at unit 0 on device "scsi.device" | partition: "DH0" sb: 3024 eb: 2099663 totb: 2096640 | Block Size: 512 Capacity: 1023.7 | partition: "DH1" sb: 2099664 eb: 23070095 totb: 20970432 | Block Size: 512 Capacity: 10239.4 found partition: "DH0" capacity: 1023.7 Megs start block: 3024 end block: 2099663 total blocks: 2096640 block Size: 512 dumping: start block: 3024 to end block: 2099663 [size: 1048319K] write from partition "DH0" to file "DH1:dump.dd"?

Simply review the Makefile and run `make`. Alternatively, * `make clean` will delete all artifacts. * `make lint` will format the code to standards. * `make dist` will prepare a lha archive with the binaries. Development is done using the `bebbo/amiga-gcc` crossdev toolchain. https://github.com/bebbo/amiga-gcc ## Authors * Roc Vallès Domènech (2022) * Christian E. Hopps (1993)
