Small command-line utilities for manipulating Acorn 8-bit filing systems ADFS and DFS

Acorn Filing System Utilities

Introduction

This is a set of utilities to work with the Acorn filing systems DFS and the 8-bit version of ADFS. The programs can work with simple disc image files that contain these filing systems and, on Linux where devices are accessible as files, on actual devices.

The utilities auto-detect between ADFS and DFS and are also able to work with disc image files from IDE emulations that have zero bytes between the real data bytes - this is also detected automatically.

Usage Summary

This is modelled after similar programs like cpmtools and dosfstools so files on the host (PC) are referred to by a simple name and files inside an Acorn filing system image are referred to with a name like:

img-file:acorn-filename

i.e. the name before the colon is the name of a disk image file or device and the name after the colon is the name of a file within that disk image.

afsls <img-file[:pattern]> [...]

afschk <img-file>

afscp [ -r ] <src> [ <src> ... ] <dest>

afsmkdir <directory> [ <directory> ... ]

afstitle <img-file> <title>

acunzip <zip-file> <...>

scsi2ide <scsi-file> <ide-file>

ide2scsi <ide-file> <scsi-file>

acornfsutils's Issues

Feature Request: Recursive copy (including directory creation)

My use case is building a ARM Eval Co Pro hard disk image from the six original floppy disks.

Some of the ARM disks contain sub-directories, for example:

$ afstree disc4.adl 
--RW----- 00000000 00000000         15 000007 !boot
D-RW----- 00000000 00000000      1,280 000340 image
--RW----- 00001000 00001000     29,832 000345 image.editor

As far as I can tell, there is no way to handle this at present with AcornFsUtils, because there is no way to create a new directory on an ADFS destination.

Do you have any thought on this?

I'm happy to do some of the implementation...

I was thinking you would need to:

1. Add mkdir() and rmdir() to the acorn_fs interface and implement these in acorn-adfs.c
2. Add a -r (recursive) option to the afscp command
3. Update the afscp code so that if a directory is encountered in the source list then it is copied recursively to the destination (creating directories as needed)

Even just (1) alone would be useful. I could then at least manually create the required directory structure.

afscp coredumps when a directory is full

Full seems to be 47 entries.

Here's a stack trace:

afschk silently ignores a non-existent file

afschk silently ignores a non-existant image file

This has tripped me up a few times.
