Other Utilities

• disbin32

  Disassemble the given raw binary using objdump.

  A shorthand for the following. (Since our memory sucks.)

  ::

  objdump -D -b binary -m i386 -M intel "${filename}" | less -FXR

• disbin64

  Disassemble the given raw binary using objdump.

  A shorthand for the following. (Since our memory sucks.)

  ::

  objdump -D -b binary -m i386:x86-64 -M intel "${filename}" | less -FXR

• hex

  ::

  hex 4567 34353637

• unhex

  ::

  unhex 4567 Eg

Caveats +++++++

pwntools_ also provide these two commands, i.e. hex and unhex, which are, however, slow.

Presumably, time consumed for the OS to load Python outweighs that needed for Python to accomplish the task.

Libraries
