This software contains the following executables:

memdump: displays /proc/[pid]/maps with percol and dumps the selected memory
  region.

memstrgrep: greps the strings in all memory regions of a process, displays the
  regions and the matches

memgrep: greps all memory regions of a process in binary mode, displays the
  regions, matches, and what offsets they're at

spread-regex: turns a single string into a string interspersed with optional
  characters. Useful for memgrep.

You need percol to use memdump.



Example usage of memgrep and spread-regex:

$ sudo memgrep 19726 $(spread-regex 32 "asdfffffffff")
b7000000-b7100000 rwxp 00000000 00:00 0 :
983056:asdffffffffff
995344:asdffffffffffffffffffff
