sets volume via command line

this will increase the volume by 2 decibels on the pcm channel. the argument to -c is for which sound card to use, the arg after set is the channel (PCM, Master, etc.) and what to set by. related commands: amixer -c 0 set PCM 2dB- decrease volume by 2 decibels amixer -c 0 set PCM toggle toggle mute/unmute this is for alsa systems for mac os (and maybe other UNIX systems) osascript -e 'set Volume *' where * is any number (can have decimal points) between 0 and 10

Clean all .pyc files from current project. It cleans all the files recursively.

check for write/read permissions

su www-apache/ftp user and then check readable: find ~/ -type d $ -wholename '/dev/*' -o -wholename '/sys/*' -o -wholename '/proc/*' $ -prune -o -exec test -r {} \; -exec echo {} readable \; 2>/dev/null check writable: find ~/ -type d $ -wholename '/dev/*' -o -wholename '/sys/*' -o -wholename '/proc/*' $ -prune -o -exec test -w {} \; -exec echo {} writable \; 2>/dev/null

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
