Show Apt/Dpkg configuration
Shows all configurations to apt and dpkg, rarely changed, you probably still have the default configuration. Go ahead and explore your configuration if you dare, perhaps change your apt-cache directory, Dir::Cache "var/cache/apt/"; or the names of the log files.

list files recursively by size

Find your graphics chipset
Displays only the VGA adapter/chipset being used for the graphics. In this case, it gave me the "M22" and "Mobility Radeon x300" that I needed to research a graphics issue I was having.

Get your commandlinefu points (upvotes - downvotes)
Like command #4845, prints score, number of entries, and average score.

Append stdout and stderr to a file, and print stderr to the screen [bash]
Useful for cron jobs -- all output will be logged but only errors will cause email to be sent. NB the order of "2>&1" and ">> logfile" is important, it doesn't work if you reverse them (everything goes to the logfile, nothing left for tee).

Install pip with Proxy
Installs pip packages defining a proxy

UPS Tracking Script

Replace all backward slashes with forward slashes
Use -i to edit file directly: sed -i 's|\\|\/|g' file

Advanced python tracing
Trace python statement execution and syscalls invoked during that simultaneously

Summarize the number of open TCP connections by state
Useful for checking the number and state of TCP connections.
