Bash script for cpp automation in CP for vim enthusiasts

cpp.sh

#!/bin/bash
# A simple bash script to automate compiling and running CP codes for vim enthusiasts
# === HOW TO USE ===
# It is recommended to split up to 4 screens: code editor (1), gcc output (2), input editor (3), output watch (4)
# and create 3 files: <name>.cpp, <name>.inp, <name>.out
# - Run "cpp.sh <name>" in gcc output (2)
# - Run "tail -f -v <name>.out" in output watch (4)
# - Code as you like in <name>.cpp file and edit input in <name>.inp, any save action in vim would trigger the script to compile and run the code
# Disclaimer: Use standard I/O, the script've already piped input and output to the program.
