Note that the one discussed is a real example of a real application.
The protection mechanism implemented was meant to only allow a binary to be run in presence of a valid license. In my case, I was asked to try and bypass the protection mechanism implemented.
This will allow you to control how a binary behaves, even when you don't have access to the source code and you can't recompile it.
In this gist I show how to disassemble and modify a Linux executable binary to change the body of a function.
Not directly through the command line, but VS Code has a Portable Mode, which lets you keep settings and data in the same location as your installation, for example, on a USB drive.Disassemble and Modify an Binary To Change a Function Can I specify the settings location for VS Code in order to have a portable version? VS Code has an Integrated Terminal where you can run command-line tools from within VS Code. How do I get access to a command line (terminal) from within VS Code? Consult the macOS specific setup topic for details.
On macOS, you need to manually run the Shell Command: Install 'code' command in PATH command (available through the Command Palette ⇧⌘P (Windows, Linux Ctrl+Shift+P)). If code is still not found, consult the platform-specific setup topics for Windows and Linux.
Try uninstalling and reinstalling VS Code. The VS Code Windows and Linux installations should have installed VS Code on your path. Your OS cannot find the VS Code binary code on its path.
If this isn't the case, you can manually add the location to the Path environment variable ( $PATH on Linux). Windows and Linux installations should add the VS Code binaries location to your system path. Note: Users on macOS must first run a command ( Shell Command: Install 'code' command in PATH) to add VS Code executable to the PATH environment variable. To do this, from an open terminal or command prompt, navigate to your project folder and type code. Typically, you open VS Code within the context of a folder. You can launch VS Code from the command line to quickly open a file, folder, or project. You will see the version, usage example, and list of command line options. To get an overview of the VS Code command-line interface, open a terminal or command prompt and type code -help. If you are looking for how to run command-line tools inside VS Code, see the Integrated Terminal. You can open files, install extensions, change the display language, and output diagnostics through command-line options (switches). Visual Studio Code has a powerful command-line interface built-in that lets you control how you launch the editor.
