By default Knoppix mounts all drives read-only, so
I'm guessing the
error is that it's unable to write somefile.bz2 to a
read-only drive
(though if you provided the actual error message I
could be more
certain). If the drive is something Linux can write
to (i.e. not NTFS),
you can remount it read/write from the file manager
(right-click and
it'll be an option in the context menu).
I know about the �read-only� problem with Knoppix
because that was one of my first problems I encounter
with that OS.
Solution:
1- mount the hard drive and remove the �read only�
2- write : sudo mount �o remount,rw /dev/hdg1
/mnt/hdg1
(hdg1 is my hdd)
After doing that I could write with no problem on the
hard drive.
My drive is NTFS because if it was on a FAT32 it would
be impossible for me to have a single file larger then
4 GB.
You can also concatenate files from a command line
in Windows (go to
start->run and enter "cmd" to get there) by doing:
copy xaa+xab+xac+xad+xae somefile.bz2
I have tried that alrady by doing:
copy /b xaa+xab+xac+xad+xae somefile.bz2 but strangely
I get a file somefile.bz2 but with the size of 1 KB
(I'm not sure what utilities on Windows can
decompress bzip2 files though.)
To decompress a bzip2 file you can use WinRar or Bzip
for Windows
bzip2 works nicely. Google it up to find the main
site, there's a win32
..exe. Or get cygwin for a full suite of Unix tools,
and do:
cat xa? | bzip2 -dc > big_darn_file.sql
I will that tomorrow, Thanks!
