- Tp, Dtp and Itp Archive Programs
- --------------------------------
-
- These programs list the table of contents and extract files from tp, dtp
- and itp Unix archives. These archive formats were used in 6th and 7th
- Edition Unix, and predate tar(1) format.
-
-
- How do I know if my file is in tp/dtp/itp format?
- -------------------------------------------------
-
- Simple. Compile tp, dtp and itp, and try doing a table of contents using
- each program:
-
- % tp t file
- % dtp t file
- % itp t file
-
- If one of them gives something sane-looking, you have probably found the
- right one, and you can use the `x' option with the same command to extract
- files.
-
-
- Caveats
- -------
-
- The programs do not use the checksums available in the archives. If the
- archive is corrupt, the programs will merrily extract garbage.
-
- mkdir -p is used to recursively make directory hierachies if they are needed.
- This could be recoded, but the programs were hacked up to do what I needed
- and I haven't fixed this yet.
-
- The programs have only had a small sample of input archives to extract. Thus,
- they may not extract all tp/dtp/itp archives. Bug reports and patches most
- welcome.
-
-
- Other Notes
- -----------
-
- I wrote these to extract archives of this type off old backup tapes. I
- hope some other people find the programs useful.
-
- I am _very_ interested in finding programs that can extract from 7th
- Edition dump/restor archives, and also from 6th and 7th Edition filesystem
- images. If you have any of these or know of them, please email me!
