Check These Out

Tail a log-file over the network
it also works with the chrome browser. The alternative with tail and nc doesn't

Shows space used by each directory of the root filesystem excluding mountpoints/external filesystems (and sort the output)

Selecting a random file/folder of a folder
I used only shuf command.

Get a list of the top 10 heaviest tables in your mysql database - useful for performance diagnostics

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

File rotation without rename command
Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name. i.e.: logfile.1.gz > logfile.2.gz I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.

Sync the existing directory structure to destination, without transferring any files

Prepare B&W scans for clean looking, searchable PDF
Scan pages in, clean them up in an image editor, save to individual files. Use this command to convert each page to PDF. Combine in Acrobat Professional, and use the built-in OCR with the "Searchable Image (Exact)" option. Gives excellent image quality and file size (avoids awful JPEG image recompression that Acrobat and other OCR systems tend to do.)

Open Remote Desktop (RDP) from command line and connect local resources
The above command will open a Remote Desktop connection from command line, authenticate using default username and password (great for virtual machines; in the exampe above it's administrator:password), create a shared folder between your machine and the other machine and configure resolution to best fit your desktop (I don't like full screen because it make the desktop panels to disappear). The command will run in the background, and expect to receive parameters. You should enter hostname or IP address as a parameter to the command, and can also override the defaults parameters with your own.

Find Out My Linux Distribution Name and Version
Another way of do it in debian like distros, don't know if works for others
