Hello,
What appeals me in this job is the fact that your terms are clear and concise , which means I would deal with someone who knows what he needs and that makes a job 10 times easier. Second ... when I hear "bash scripting" I feel an urge to do it, cause this is what I enjoy most in my work.
If further details are just as clear as your job description is already, then I can deliver in less than one day.
looking forward to work with you
kind regards
Adrian
