Check These Out

ionice limits process I/O, to keep it from swamping the system (Linux)
This command is somewhat similar to 'nice', but constrains I/O usage rather than CPU usage. In particular, the '-c3' flag tells the OS to only allow the process to do I/O when nothing else is pending. This dramatically increases the responsiveness of the rest of the system if the process is doing heavy I/O. There's also a '-p' flag, to set the priority of an already-running process.

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

To create files with specific permission:

Annotate tail -f with timestamps

multiline data block parse and CSV data extraction with perl
extract data in multiline blocks of data with perl pattern matching loop

Chrome sucks

sed edit-in-place using -a option instead of -i option (no tmp file created)
does the -i option open a tmp file? this method does not.

convert a web page into a png
This requires the command-line print extension (see #2861 for more details). I use it to make up complex images with formatted text using CSS and whatnot. It's a lot slicker than imagemagick for certain things. Now imagine using a local webserver with PHP and a database to generate the images. Oh, the possibilities...

Toggle between directories
switch to previous directory or toggle

Find the package that installed a command
