Basic VIM Keys

Notes

• a number in front of most movement and edit keys acts as a multiplier to that key
  • e.g. 30j moves the cursor down 30 lines and 3i tora types toratoratora
• editing can be stacked with movement characters
  • e.g. dw will delete a word

Path

1. Manifest contains information about a job to start in either the

2. configuration templates/"spec" (from cf-release/jobs/<jobname>/) + stemcell + packages (from cf-release/packages)

3. magic from the BOSH Director (prepare) takes the stemcell and starts it and lays over package info and configs in /var/vcap

Mint Upgrade Notes

From http://community.linuxmint.com/tutorial/view/62 and from here https://gist.github.com/hgomez/7074150.

This page http://www.tecmint.com/upgrade-linux-mint-16-to-linux-mint-17/ was less helpful but usseful to see the whole process including screens.

1. Open a terminal and run 'sudo bash' to get a root terminal

2. Using a text editor (as root), replace the release names in the /etc/apt/sources.list using your editor of choice

Generate a list of users with a uid greater than 500

awk -F: '$3 > 500 {print $1}' /etc/passwd

Look for users with a space after the username grep " :x" /etc/passwd

It is possible to set the TZ variable on a per user or even per script basis.
