ShrinkIt to disk image on Mac/Linux command line

[Ivan X]

ADTPro provides a command-line version of AppleCommander, which is pretty handy for getting stuff in and out of Apple II disk images (and many formats are supported, and automatically detected).

I've written a couple of functions for Bash which allow you to access AppleCommander easily (with the command "ac"), and also extract all the files in a ShrinkIt archive directly into a ProDOS disk image file ("shk2image").

Also, when writing a file into a disk image with AC's -p argument, you can specify the file type by two-digit hex rather than the three-letter name AppleCommander seems to normally require (e.g. 04 instead of TXT).

It should work on both OS X and Linux (or at least Debian-flavored Linuxes), with Java installed. Put these functions in ~/.bashrc (Linux) or ~/.bash_profile (Mac), or /etc/profile (either, and will work for all users). On a Mac, the ADTPro folder needs to be in /Applications. On Linux, the ADTPro folder (or a symlink to it) needs to be called "adtpro" and in /usr/local.

When using shk2image, if the disk image name you provide doesn't exist, it will be created (140K if the name ends in ".dsk", 800K otherwise). Any file in the disk image with the same name as the one you're extracting will be overwritten. You can also provide an optional ProDOS directory name to install into, and it will be created if necessary. Do not put a leading or trailing slash in the directory name.

Hope a few of you find these useful. I'll also be including them in an update to A2CLOUD.
