harava

Memory scanner/editor for Linux

Warning

This program might consume a significant amount of RAM in certain situations. By default, it has an 8GB limit to prevent system crashes, but temporary usage beyond this limit may occur

Features

• Search for selected data types or all of them at once
  • Supports signed integers (4 and 8 bytes), floats and doubles
• Modify memory values
• Filter with different comparison operators or find values that have or have not changed since the previous scan

Example usage

First figure out the PID of the process with pgrep etc.

pgrep -i <process_name>

Then give the PID to harava with the -p flag. You can also directly pass the PID via shell expansion

./harava -p $(pgrep -i <process_name>)

After harava has identified the memory regions to access, use the help command for a list of available commands

Building

Note

If cloning from git, remember to clone with the --recursive flag

Build the project with cmake by running the following commands

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j$(nproc)

On some platforms you might also need to use the -DCMAKE_CXX_FLAGS=-ltbb flag with cmake

Installation

To install harava to /usr/local/bin, run the following command

sudo make install

You can customize the installation PREFIX and DESTDIR variables normally with cmake and make.
