Show Notes:
-the ls command and it's switches (-l -h -r -S)
-setting yourself up for a good command line experience
-Why? easy to see files vs folders
-possible to put prompts on different machines in different colors.
-Exercises using escape characters
SAVE=$PS1
PS1=$
PS1="$ "
PS1="\u@\h \W> "
PS1="[\t][\u@\h:\w]"
-Add color with:
\[\033[1;34m\]
-the 1;34 part is the color
-If you've messed things up you can restore you prompt back to what it was by typing:
PS1=$SAVE
-Add color when using "ls" by adding this to you ~/.bash_profile
export CLICOLOR=1
export LSCOLORS=ExFxCxDxBxegedabagacad
-When you have your commandline the way you want it save it in ~/.bash_profile (or sometimes ~/.bashrc)
To load your changes without exiting out of the terminaltype:
source ~/.bash_profile
