I just wonder if you could use Squeak shell to pipe stuff through a bash script....

Yes. Well, sort of. There is a bit of an impedence mismatch between Squeak objects and the streams of characters which a bash script expects to see on its input.

Thus the importance of a proper line terminator. Used to have this problem with AppleTalk before I switched to ethernet...

I think that there is two things being confused here:

First, squeak has a 'binary' format for changesets and projects. This format is supposed to be portable between all of squeaks platforms. The fact that this format is ASCII text with Mac line-ending conventions doesn't change the fact that it is intended to be a binary output.

Second, squeak should have the ability to export a seperate, different non-portable, platform-dependent format for storing this text, which uses platform line-ending conventions. There may also be an import operation which can either read the platform-dependent format, or can attempt to be intelligent and guess line-endings. (and thus can read files exported by squeak on other platforms).

The two are semantically different, and I think that some of the confusion is caused by not distinguishing between their purposes.

We should not convince squeak to use LF or CR as a line seperator. What it uses for its internal platform-independent format should be irrelevant. (IMO, maybe it would be easier to solve this confusion by having squeak gzip this data, to emphasize that it is not intended to be modified or viewed as-is.)
