Script shell example

This script shell is a good starting point to build a bash shell script.

• Why bash instead of sh ?
  Though sh is faster and should be prefered for large scale automation scripts, Bash has more functionalities and is kinder with humans.

• Is there a linter for bash scripts ?
  Yes, use shellcheck to validate your script :

$ shellcheck example.sh

In example.sh line 11:
RED=$(tput setaf 1)
^-^ SC2034: RED appears unused. Verify use (or export if used externally).


In example.sh line 12:
YELLOW=$(tput setaf 3)
^----^ SC2034: YELLOW appears unused. Verify use (or export if used externally).


In example.sh line 13:
GREEN=$(tput setaf 2)
^---^ SC2034: GREEN appears unused. Verify use (or export if used externally).


In example.sh line 14:
BOLD=$(tput bold)
^--^ SC2034: BOLD appears unused. Verify use (or export if used externally).
