- in case anyone is interested, i pulled down perfpich.tos (a "controversial"
- self extracting zip archive) to see if it can be dealt with on a unix
- system. i ran unzip -l on it (version 4.0) and got:
-
- Length Date Time Name ("^" ==> case
- ------ ---- ---- ---- conversion)
-
- error: expected central file header signature not found (file #0).
- (please report to info-zip@wsmr-simtel20.army.mil)
-
- NAK! obviously it cannot deal with it. a casual user would either thro it
- away (assuming of course that he knew it was a zip file) or send mail
- to simtel and report a bug that wasn't.
-
- however, since i am not a casual user, and keep tabs on the "pulse", i
- remembered that a week or two ago, a new version of unzip was posted to
- comp.sources.misc, so i built it (version 5.0). it did better (again,
- unzip -l):
-
- Length Date Time Name ("^" ==> case
- ------ ---- ---- ---- conversion)

- warning: extra 4448 bytes at beginning or within zipfile
- (attempting to process anyway)
-
- so, unless u have a brand new "unzipper", you can't deal with this sort
- of archiving method. and as warwick pointed out, u can't tell what sort
- of file this is (except a tos executable) by its name. finally, its
- SE header takes up an extra 5KB on disk (to store the extra 4448 bytes).
-
- u can probably find unzip 5.0 by checking the usual list of usenet
- archives for c.s.misc. please don't ask me for it!
-
- now i look forward to actually playing with this puppy. oh, yeah, it
- extracted fine with unzip 5.0. incidently, this is a tool to develop/test
- a sense of (musical) perfect pitch (ie, it plays a note on one keyboard
- and you play what you think is the correct note, without any audio cues).
- time to see if i still got it. i could do this on sax, i don't know about
- keyboards tho. time to buy a wind controller, i guess... :-)
