refactor: bash scripts [stip travis]

- shellchecke and shfmt checked and formatted
- indentation 2 spaces
- redirect errors to stderr
- short if where possible
- add function string to clarify visuaally identify its a funtion
- make [ ... ] to [[ ... ]]
- use == for comparision
- use cat based notes
- remove unecessary spaces
- double quotes where needed
