Bash Script Best Practices

Must have a check argument section

Example:

# To check if the argument must be equal to 1 and there should be gap between [[ in ]] if block.
# In this following example: "$# -ne 1"
if [[ "$*" =~ "--help" || "$*" =~ "-h" || $# -ne 1 ]]; then
  usage
fi

Must have a Usage section

Example:

function usage(){
  echo ""
  echo "USAGE: $0 [ -h, --help, arg1 ]" 1>&2;
  echo "Example: $0 arg1"
  echo "Some more details over here."
  echo ""
  exit 1;
}

..NOTE::

# In variable there should not be spaces. agr1=$1

vi session-script #!/bin/bash ssh-add /path/to/key bash -i # or other session starter

ssh-agent session-script
