Trouble Shooting:

• Start with the basics...like power, network, etc.

General:

• Know the animal before trying to tame
• Some vendors use MB/GB (decimal...1000s) and some use MiB/GiB (binary...1024s)
• Always query before running modification command(s)
• Backup or already have a backup before modifying files
• Learn your editor(s) well...it's functions can save a ton of time
• Always tail -f error logs when developing

Development:

• Naming
  • Avoid spaces.
  • Use camelCase.
  • Name common items with the common word starting each item.
  • Name same item, but numbered with enough padding to sort correctly. ex: if going to at least 10 use 01-10 instead of 1-10.
  • Name date by number not name and most general to specific. So they sort correctly. ex: 20161231 instead of Dec31-2016, etc.
  • Name using noun first then verb. ex: logCreate, logList, etc.

• Coding
  • Top-down and bottom-up design
  • Always add comments
  • Line block brackets up vertically
  • Happy balance between elegance/complexity and readability/maintainability
  • Happy balance between too long and too short variable naming
  • Pick a style and stay consistent
  • Learn your debugging tool(s)...they can save a ton of time

*nix:

• Use "set -x" to debug shell scripts ("set +x" turns it off)
• Use "set -o vi" to use vi to navigate/modify shell commands ("set +o" turns it off)
