Sir,
Read my profile, im a 25yo, Master Degree in IT but years of experience, linux user since I was 12 years old!
I've been working at a hosting company / ISP which is reallyu cool since everything from digging and put the fiber into the floor, from router to server & linux OS, made me incredibly good at troubleshooting.
I have bash experience. you didnt provide error message biut I assume either the original programmer used another bahs version, or wrong seebang, or worse n no sheebang, idk.
Let me look (im french. Besoin d'argent pour la moto cross c'est lété ! stppp)
