# Previous directory

No, not `cd ..`. That is go UP a directory.

`cd -` works magically

# Browsing history

Next command from history:     `Ctrl+n`
Previous command from history: `Ctrl+p`

Run the command: `!!`

# Expansions

`cp file.txt{,.bak}`

is equivalent to

`cp file.txt file.txt.bak`

Also, you can expand stuff like {1..10} and {a-z}:

`for i in {1..10}; do ...; done`

# For vim purists

Bash has vi-mode!

`set -o vi`
