apt-get upgrade with bandwidth limit
in Debian-based systems apt-get could be limited to the specified bandwidth in kilobytes using the apt configuration options(man 5 apt.conf, man apt-get). I'd quote man 5 apt.conf: "The used bandwidth can be limited with Acquire::http::Dl-Limit which accepts integer values in kilobyte. The default value is 0 which deactivates the limit and tries uses as much as possible of the bandwidth..." "HTTPS URIs. Cache-control, Timeout, AllowRedirect, Dl-Limit and proxy options are the same as for http..."

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.

archlinux: shows list of files installed by a package
Shows the files which the package, for example gvim, installed on your system.

Blank/erase a DVD-RW

Ping a range of addresses

find text in a file
this will find text in the directory you specify and give you line where it appears.

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

list files recursively by size

Create a mirror of a local folder, on a remote server
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

Sort the size usage of a directory tree by gigabytes, kilobytes, megabytes, then bytes.
Probably only works with GNU du and modern perls.
