tweak (ncurses-based hex editor)
|
|
|
|
Tweak is a hex editor. It allows you to edit a file at very low level,
|
|
letting you see the full and exact binary contents of the file. It can be
|
|
useful for modifying binary files such as executables, editing disk or CD
|
|
images, debugging programs that generate binary file formats incorrectly,
|
|
and many other things.
|
|
|
|
Tweak uses a complex data structure based on B-trees, designed to make
|
|
almost all editing operations extremely fast, even when they are working
|
|
on huge amounts of data.
|
|
|
|
Tweak supports insert mode (not particularly useful if you're editing
|
|
an executable file or a filesystem image, but can be extremely handy in
|
|
other file formats such as PNG).
|
|
|
|
Cutting, copying and pasting within the file you are editing is extremely
|
|
efficient. No matter how big the chunk of data you are moving around -
|
|
even if it's a 200Mb section of a CD image - Tweak will always perform
|
|
the operation effectively instantly.
|
|
|
|
Tweak supports lazy loading of the input file: rather than sucking it
|
|
all into memory straight away, it simply remembers which parts of the
|
|
editing buffer are copies of which parts of the input file and refers to
|
|
the file on disk when it needs to.
