Try to be standard

You may use bash scripts from GitHub, and you may notice that there is a standard option scheme that is followed. It's not required, but it is preferable.

These are some of the commonly used options:

• -a: List all items
• -c: Get a count of all items
• -d: Output directory
• -e: Expand items
• -f: Specify a file
• -h: Show the help page
• -i: Ignore the character case
• -l: List a text
• -o: Send output to a file
• -q: Keep silent; don't ask the user
• -r: Process something recursively
• -s: Use stealth mode
• -v: Use verbose mode
• -x: Specify an executable
• -y: Accept without prompting me
