Generate Linux executables with missing dependencies

generate_exe_with_unmet_dependencies.sh

#! /bin/bash

# USAGE:
# generate_exe_with_unmet_dependencies.sh OUTPUT_EXECUTABLE_NAME NUMBER_OF_DEPS
# Generates an executable with the specified file name, which will dynamically
# link against the specified number of libraries, These libraries will have
# randomly generated names. They'll be removed once the main executable is
# complete and should always be missing on anyone else's system; therefore the
# generated executable is guaranteed to always fail due to missing dynamic
# libraries.
