Today started off with a great presentation from Derek Carter from Coraid on Bash scripting. I'm an old hat at Bash, and even I learned a few things. This was certainly a popular topic as evidenced by the overflowing room. Derek did not disappoint. Particularly I'm excited by pv, pbcopy/pbpaste, todo.sh, [[]], zenity.

Miscellaneous Notes:

• Sponsored by Coraid
• variables: RANDOM, PS1, PS2
• DOOD=${RANDOM}
• let "DOOD %= 500"
• PS2 shows up when you leave a quote open (default '> ')
• tmux - like screen, but re-imagined
• byobu - superdooper screen customizer
• pv - progress bar in terminal. uses stdin stdout
• todo.sh - todotxt.com
• mkcd () { mkdir -p -- "$@" && cd -- "$@" }
• pathmunge - redhatism
• .inputrc - bind keys to inputs - look for readline in bash manpage
• bti - bash twitter idiocy. bash twitter client
• PROMPT_COMMAND - runs every time you get a command
• if [[ ]] - double brackets? - bash builtin instead of tests
• if then : - colon is placeholder
• macosx bash tools - sounds cool
• pbcopy/pbpaste would be handy
• xyzzy - record bash sessions
• terminator - gnome-terminal splittable
• trap - trap kill signals to a function
• dialog - read input via curses. gets very complex. uses temp files.
• zenity - gtk-based dialog. can run as subshell.
• kdialog - kde-based dialog
• stringent.sh - variable typing
