[Coco] Extracting OS-9/6809 .lzh files today?

[L. Curtis Boyle]

Found my copy of LZH (not to be confused with LHA or UNLZH). I did briefly use this in the 1990’s, but I remember compatibility problems with any other OS’s, so I reverted to LHA (which was compatible with Windows, DOS, Amiga, etc. at the time).

Here is the help screen for LZH:

Lzh 1.0 - OS9/6809 LHArc by Matthew Thompson 1993

Usage: lzh [-]<cmd>[opt] <arcfile[.lzh]> [file1] [file2] [...]
  <cmd> is one of:
    l  list contents, default if just <arcfile> given
    x  extract files
    p  print to stdout
    a  add files
    t  test archive
  [opt] is any of:
    s  store files, do not compress
    q  quiet, no info printed
    c  convert filenames to/from uppercase
    i  ignore pathlists
    e  exclude extended header

Filenames can include wildcards (*, ?) or pathlists.
