So, you want a hex editor for your latest project and (naturally) you decide to have a look at Hexxed, the free, GPL licensed, hex editor you can download here: http://220.127.116.11/hexxed.jar. So what happens next?
bash-3.2$ java -jar hexxed.jar -u
usage: hexxed [options]
-b,–block use block:offset address output – default is
-be,–bigendian interpret data as big endian – default is cpu
-f,–file <arg> file to edit
-le,–littleendian interpret data as little endian – default is cpu
-o,–offset <arg> offset in file – default 0
-s,–blocksize <arg> size of block if block:offset addressing used –
default is 0x200
-u,–usage show this information
-w,–width <arg> width (in bits, 8 – 64 bits) of output data –
default is 8 bits
-x,–x <arg> width of window (default 640 pixels)
-y,–y <arg> height of window (default 480 pixels)
Subtext is, please do have a look at Hexxed. I know it’s not as fully featured as commercial or even other free hex editors, but this is just the first iteration and if you tell me it is useful and add what feature you’d like to see in it, it is quite likely that I will get on with adding it.
Update: I have now run Hexxed on Ubuntu and Debian Linux, Mac OSX and Windows XP, so it should work on anything with Java installed.
