Find the package that installed a command

Remote screenshot
The `export` is unnecessary if it's only applicable to the one command.

FInd the 10 biggest files taking up disk space
This combines the above two command into one. Note that you can leave off the last two commands and simply run the command as "find /home/ -type f -exec du {} \; 2>/dev/null | sort -n | tail -n 10" The last two commands above just convert the output into human readable format.

Set your profile so that you resume or start a screen session on login
From screen's manpage: "Attach here and now. In detail this means: If a session is running, then reattach. If necessary detach and logout remotely first. If it was not running create it and notify the user. This is the author's favorite." Toss this in your ~/.bash_profile so that you never have that "oh crap" moment where you wanted to run something in screen and didn't.

faster version of ls *
I know its not much but is very useful in time consuming scripts (cron, rc.d, etc).

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"

list block devices
Shows all block devices in a tree with descruptions of what they are.

Given $PID, print all child processes on stdout
Simpler.

split a multi-page PDF into separate files
Have to do this once per output file, because if device is 'pdfwrite', even if 'gs' sees '%d' in the OutputFile it still only creates one single output file. Embed it into a simple shell script if you want to split a document out into one file for every page.
