Why does a script written in Bash refuse to work?

Question

bash

Good evening, I wrote a bash script for auto-installation.
I don't understand why it refuses to work.
The script itself posted on the poison. Because it doesn’t let it in here because there are a lot of characters
Link to the script: https://github.com/bbk96/autoinstall/blob/master/d...
Here is the log from the console:

: not foundh: 2: deb7.auto.sh:
: not foundh: 7: deb7.auto.sh:
: No such file7: deb7.auto.sh: cannot open /tmp/log.pipe.3016
: Interrupted system callo.sh: cannot create /tmp/log.pipe.3016

Answer 1

Good evening, I wrote a bash script for auto-installation.

/bin/sh may not be bash.
Scripts can be debugged:#!/bin/bash -ex

Answer 2

Try to solve the problem "on the forehead", with bash it very often helps to understand the reason - just copy-paste (taking into account the variables, of course) perform all operations in the console and check the result. It only seems to be complicated and time-consuming - but in fact it will be faster than waiting for someone else to do it, besides, such code that is "debugged" in a virtual machine, at least, few people want to check ..
