I had to split this 2.6 GB zip-file in order to send it thru a slow uplink. I did this:
split -b 879m BIGFILE.zip
This created xaa, xab & xac which I uploaded to the remote server. After the transfer finished I verified each one of these 3 pieces with md5sum (both on my local system and on the server):
md5sum xaa md5sum xab md5sum xab
All of the 3 hashes were identical to that of the 3 ones on my system so the transfer went well. Now, on the remote system, when I do this:
cat xa* > BIGFILE.zip
...then I verify the hash of this BIGFILE.zip (on both systems):
...and both of them match.
Now comes the interesting part. When I try to list the contents of the zip file I get an error:
unzip -l BIGFILE.zip
Archive: BIGFILE.zip End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of BIGFILE.zip or BIGFILE.zip.zip, and cannot find BIGFILE.zip.ZIP, period.
This is totally weird. I'm using the same version of "unzip" on both systems. When I use the "unzip -l" on my local system it works.
Thanks for any help. JFA
