# loada

`loada` loads (restores) legacy Data General AOS/VS DUMP_II, and maybe DUMP_III, files on any modern Unix-like system supported by GNAT Ada.

It can be used to rescue data from legacy AOS/VS systems if the dumps are accessible on a modern system.  

The current version handles at least versions 15 and 16 of the DUMP format.

This software is a port of the LoadG utility from my https://github.com/SMerrony/aosvs-tools programs.

As of March 2021 it is believed to be functionally equivalent to that program and shares the same SemVer.

## Build

Use the `gprbuild` command in the directory where you unpacked or cloned this software.

## Usage

```

./loada

Usage of loada:

  -dumpfile   DUMP_II or DUMP_III file to read/load (required)

  -extract          extract the files from the DUMP_II/III into the current directory

  -ignoreErrors     do not exit if a file or link cannot be created

  -list             list the contents of the DUMP_II/III file

  -summary          concise summary of the DUMP_II/III file contents (default true)

  -verbose          be rather wordy about what loada is doing

  -version          show the version number of loada and exit

  ```

To list the contents of a dump: `./loada -dumpfile ACK.DMP -summary`

To extract the contents of a dump `./loada -dumpfile ACK.DMP -extract` 

### Notes

 * All files and directories will be created using upper-case names

(the AOS/VS file system was case insensitive) 

 * Subdirectories found in the dump are created as needed

 * Link files will be created as symbolic links

 * ACLs (file permissions) are ignored

 * `loada` will not traverse above the current directory (this was legal in AOS/VS dumps) 

 * Will not build on Windows due to lack of symlinks
