<Line eaters sure do have heavy appetites.> Does anyone have a version of compress/uncompress that will work on the Amiga and uncompress the files from the Purdue archives? I have downloaded the one from Purdue, but itlways returns an error - file not in compressed format. Any help would be appreciated.

The `compress/uncompress' on the Fred Fish disks (master sources on Disk #6, several updates on Disk #51) should work fine for you; I use the executables from FF#51 almost daily without ANY problems whatsoever, and I've recompiled the sources on my 3B1 and the program(s) function fine there, too. If you cannot locate (at least) FF#51 locally, I could uuencode/shar/post the stuff to you.

If you don't, the compressed files can be corrupted by the transfer. The files uncompress just fine on my Amiga. In any case, there will be a new version of Amiga compress coming out "real soon now." This one will dynamically allocate the memory it needs (previously, this was controlled by a compile-time option), and look for an environment variable with a default number of bits (Manx style environment). I'm "almost finished" with it, eh? -- Brent Woods, Co-Moderator, comp.{sources,binaries}.amiga USENET: woodsb@killer.UUCP USNAIL: 320 Brown St., #406 / W.

It appears that the version of compress in the archives at Purdue will only handle a max of 13 bit compression and Pat (White) uses 15 bit compression for the archives. Kjohn indicated there would be a newer version available at AmiExpo and I hope to be able to pick it up. For those who sent advice, I do use BINARY when FTP'ing and can download, etc., just fine, but I have to use the UN*X version of uncompress on the LOGNET2 system. It would certainly save time if I could download the compressed file to my Amy and uncompress/unshar/uudecode/dearc/etc on Amy. If I am not successful after AmiExpo, I will put up another request for help. Thanks to all who responded.

I don't know what a GOOD (useable) UUCP address would be. I only know the ARPANet address above. I'll try to figure it out if needed after AmiExpo. Thanks and keep up the terrific support!

Say.. Could someone give me some idea where to find UNCOMPRESS for the\
amiga? I DLed COMPRESS, but no UNCOMPRESS utility. Are you supposed to
use COMPRESS by itself or with an argument to UNCOMPRESS files with
the .Z extention... ? Any help, hints, and/or money would be appreciated.\
Thanks,

compress IS uncompress! There's a command-line flag to let you uncompress, and if you NAME it uncompress, it will uncompress by default!

The docs for version of compress I have say to copy compress to another file called (you guessed it) uncompress. Suposedly the program checks its file name to decide if it should compress or uncompress stuff. I believe that there is a command line flag, like '-u,' which causes 'compress' to uncompress things too.

There's two ways to invoke uncompress. One, type 'compress -d <filename>' to uncompress <filename>.Z. Two, make a copy of compress and name it uncompress. Compress looks at the command line to find out how it was called, and responds apropriately. In fact, there is a third function in compress, called 'zcat'. This does an uncompression of the file, but sends the output to stdout, instead of another file. Pipe it into more, and you can read compressed files without uncompressing them onto the disk. (Unix systems do this by having one copy of compress, and then using symbolic links to it named uncompress and zcat. Oh, for symbolic links on my Amiga...) | Thanks, | Fred (pyr464!psc90.uucp) You're welcome. I hope this helped. --dds Dale D. Snell dales@teksce.SCE.TEK.COM 74756.666@compuserve.COM

Would the world not be a better place if we could simply (ala Unix) link 'uncompress' to 'compress'? Somehow in my warped mind I think so.

Somehow in my warped mind I think so. I agree, though I would probably still continue to use my ARexx script that front-ends for uncompress. It builds the command line if it's a file I name in the args, and uncompresses everything in a directory if I specify a directory. -larry -- My name is OS/2, Mandius, Kludge of Kludges.

Somehow in my warped mind I think so. > . . . > {pyramid|rutgers|uunet}!cbmvax!heimat!sneakers ***** It seems to me to be a question of whether a linking arrangement would use more or less memory than alias uncompress compress -z where 'z' is the correct flag. Since the linking system is hypothetical, I don't know the answer. But my guess is that the alias would be more memory efficient. Execution speed is not a serious issue when the user is interactive. (That is, unless link references are incredibly slow, since both things will happen very fast from the interactive user's perspective.) And if it's being done in a script, ... Links would be useful for other applications that I know of in high end systems. < Defensive comment. I'm not arguing against links. ------------------------------------------------------------------------ William F.

Since the linking system is hypothetical, I agree in this case an alias would work just as good. A link would require disk space where an alias requires memory.
