I don't have a separate system, but I tried the strings output of the tar before compression and the strings output of the tar -after- compression and uncompression - as I mentioned the size output is only two bites difference. The result was that the memory was exhausted on attempting a diff of the two files, but there was around a 1 meg difference between the two 1.5G ascii files. > Sorry if this was specified before, but did this just start happening > or is this the first time you've tried to gzip large files on this > system? first time I have tried files of this size - but I get the same problem no matter what compression utility I use; tried gzip, bzip2, rzip and compress.
