A Bad Written Video Cutter for Data Preperation

vidcut.sh

#!/bin/bash
function vidcut2() {

    echo "Illegal number of parameters. It should be greater than 3."

How To Use It

1. add this file to ~/bin
2. in ~/.bashrc: add the following

# For custom commands
export PATH=$PATH:~/bin
source ~/bin/vidcut.sh

3. open a command prompt in the directory where you store your input file
4. do command `vidcut{number_of_cut} {absolute_file_name} {the_end_of_firt_cut} {the_end_of_second_cut}

Complains

I hate this tedious data prep!
