I seem to recall seeing that you could unzip files on the 770. I do know that FBReader can read text and html files insize a zip archive without unzipping, although I have no idea what that means in general.
Anyone have definitive information on whether the 770 has zip/unzip capabilities?
man gunzip
"gunzip can currently decompress files created by gzip, zip, compress, compress -H or pack'

Files created by zip can be uncompressed by gzip only if they have a single member compressed with the 'deflation' method. This feature is only intended to help conversion of tar.zip files to the tar.gz format. To extract zip files with several members, use unzip instead of gunzip.
There does appear to be some support for ZIP files. As stated on a different thread, the backup utility generates ZIP files. However, I don't think that there is a standalone utility on the device that can handle ZIP files. At least, I haven't been able to find one. Apparently, the zlib library, which is installed on the 770 (from the zlib1g package), can be built in such a way that it supports ZIP files, so this might be where applications are getting ZIP file support.
No, there are no man pages on the device, presumably to save space. A list of packages that are installed as part of the default firmware and developer's firmware can be found at http://repository.maemo.org/unstable...reference.html . man-db is the name of the Debian package that includes the man utility, and it is not installed for either the default firmware or developer's firmware.

I did not find a command-line Zip utility on my 770. FBReader probably uses a library, rather than an external command, to handle Zip files. However, I did find a site that had a precompiled command-line binary of UnRar for ARM Linux platforms (like the iPaq, for example), so just for kicks I installed in /usr/bin on my 770. It seemed to work fine. So, assuming you have some basic Linux knowledge, it probably won't be too hard to find a compatible utility for Zip, even if you're not comfortable compiling your own software.

Pardon me if I am being naive, but isn't it just a matter of recompiling unzip using scratchbox et al as taught here?
