ext2ed - The extended-2 filesystem editor, version 0.1
|
||
|
|
------------------------------------------------------
|
||
|
|
|
||
|
|
This is version 0.1 of ext2ed - The extended-2 filesystem editor.
|
||
|
|
|
||
|
|
Documentation
|
||
|
|
-------------
|
||
|
|
|
||
|
|
ext2ed's documentation consists of three documents:
|
||
|
|
|
||
|
|
1. The user's guide.
|
||
|
|
2. Technical overview of the ext2 filesystem.
|
||
|
|
3. The EXT2ED design and implementation document.
|
||
|
|
|
||
|
|
Those documents are available in the doc directory, in linuxdoc-sgml and
|
||
|
|
postscript formats.
|
||
|
|
|
||
|
|
The documentation is also available online at:
|
||
|
|
|
||
|
|
http://tochnapc2.technion.ac.il
|
||
|
|
|
||
|
|
under the ext2ed section.
|
||
|
|
|
||
|
|
Installation
|
||
|
|
------------
|
||
|
|
|
||
|
|
ext2ed requires the kernel sources and the readline and ncurses packages.
|
||
|
|
Please edit the makefile if you are using an "old" version of ncurses (See the
|
||
|
|
details below) or if gcc can't find the various header files and libraries.
|
||
|
|
|
||
|
|
To install, simply issue a 'make' command to compile and a 'make install'
|
||
|
|
command to install. I have also included an already compiled linux a.out
|
||
|
|
binary.
|
||
|
|
|
||
|
|
ext2ed and ncurses
|
||
|
|
------------------
|
||
|
|
|
||
|
|
ext2ed uses the ncurses library for terminal output. It is very important
|
||
|
|
that ncurses will be properly installed on your system:
|
||
|
|
|
||
|
|
1. Old versions of ncurses (around 1.8.5) need the OLD_NCURSES compile
|
||
|
|
time option in EXT2ED.
|
||
|
|
|
||
|
|
At least from 1.9.2c, this flag should not be used. I would recommend
|
||
|
|
upgrading the ncurses library to the newer versions.
|
||
|
|
|
||
|
|
2. ncurses uses its own terminfo database rather then the termcap file.
|
||
|
|
It is important that the terminfo database will be found by ncurses.
|
||
|
|
If this is not the case, you will see on startup some lines which
|
||
|
|
refer to /etc/termcap. This will mean that there is a problem with
|
||
|
|
the terminfo database.
|
||
|
|
|
||
|
|
3. Newer versions of ncurses (and the 1.3 series of the kernel) describe
|
||
|
|
the linux console in the entry 'linux' and not 'console', as it was
|
||
|
|
before. If you run ext2ed in the linux console, you should either
|
||
|
|
set your TERM environment variable to 'linux' or link
|
||
|
|
l/linux to c/console in the terminfo database.
|
||
|
|
|
||
|
|
4. The percompiled binary was linked with ncurses 1.9.4 and will search
|
||
|
|
for the terminfo database on /usr/local/lib/terminfo. If you are
|
||
|
|
using it, and your 1.9.4 compatible terminfo database is not on the
|
||
|
|
directory above, use the TERMINFO environment variable to specify
|
||
|
|
an alternate location.
|
||
|
|
|
||
|
|
Running ext2ed
|
||
|
|
--------------
|
||
|
|
|
||
|
|
For those of you who don't like reading lengthy articles, here are a few
|
||
|
|
basic guidelines:
|
||
|
|
|
||
|
|
1. Don't use ext2ed to change a mounted filesystem !
|
||
|
|
|
||
|
|
Using ext2ed in read-only mode on a mounted filesystem can be allowed
|
||
|
|
by using the configuration file option 'AllowMountedRead on'. However,
|
||
|
|
note that the displayed data will be unreliable.
|
||
|
|
|
||
|
|
2. ext2ed currently can't handle filesystems bigger than 2 GB. I am
|
||
|
|
sorry for the inconvenience. This will hopefully be fixed in future
|
||
|
|
releases.
|
||
|
|
|
||
|
|
3. Before running ext2ed, edit the configuration file
|
||
|
|
/var/lib/ext2ed/ext2ed.conf to suit your needs. The various
|
||
|
|
configuration options are documented there.
|
||
|
|
|
||
|
|
4. Use the 'setdevice' command to open an ext2 filesystem.
|
||
|
|
e.g. 'setdevice /dev/hda1'.
|
||
|
|
|
||
|
|
5. If the filesystem is an ext2 filesystem and ext2ed fails to
|
||
|
|
autodetect this, use the 'ForceExt2 on' configuration file option.
|
||
|
|
|
||
|
|
6. The filesystem will always be opened in read-only mode. Feel free to
|
||
|
|
experiment, but take care with the 'enablewrite' command.
|
||
|
|
|
||
|
|
-----------------------------------------------------------------------------
|
||
|
|
|
||
|
|
Feel free to send me feedback with anything regarding to ext2ed.
|
||
|

|
|
Enjoy,
