This could mean you have a hardware problem.  Have you rebooted or run
fsck lately?

Try "unzip file.zip".  If it says "command not found", install zip and
unzip.

Try "unzip file.zip".  If it says "command not found", install zip and
unzip.

so I tried:
----------------------------------------------------------------------------
------
root@etutor:~ # unzip *.zip
Archive:  myfile2.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.
note:  myfile2.zip may be a plain executable, not an archive
unzip:  cannot find zipfile directory in one of myfile2.zip or
myfile2.zip.zip, and cannot find myfile2.zip.ZIP, period.
root@etutor:~ #
----------------------------------------------------------------------------
-
that zip file is from window xp platform, it can somehow be unzip by
winzip(or winunzip).

looking for further advice

file myfile2.zip

If you used ftp to get myfile2.zip, you may have forgotten to use binary
mode.

try

dd if=/cdrom/path/myfile.zip of=/dev/null

if it gives input/output error too, then your cd-rom disk (not drive)
seems to be damaged.

zip files aren't handled by gzip and company (despite the fact that
gunzip can decompress some .zip files).  There two packages for them zip
and unzip.  Install, RTFM, enjoy.

Let me explain a difference.  gzip file (with .gz extension) is *one*
regular file compressed in one compressed-file.  So are bzip2 files
(with .bz2) too.  .zip, .rar, .arj etc files from the other OS-like
platform (you know) are many files amassed in one *archive* by the way
compressed.  In the POSIX world *archiving* is perfomed using tar, cpio,
shar etc.  Some of them can be managed to compress files itself,
(afaicr) with some restrictions.  (imho) That's not a habit.

Hint.  In order to find apropriate tool discover a utility named `file'.

sspaces are end of word markers in Linux. You eitehr need to escape the
spaces
my\ some\ window\ file.zip
or single quote them
'my some window file.zip'
to prevent bash from interpreting the spaces as end of word markers.

try:
# dd if='/cdrom/my some window file.zip'  of=/dev/null

(single quote around the whole path.)

Your cdrom was burned badly.  Download the iso and try again.
