Check These Out

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

Using netcat to copy files between servers
It bypasses encryption overhead of SSH and depending on configuration can be significantly faster. It's recommended to use only in trusted networks.

check open ports without netstat or lsof

Rename files in batch

Updated top ten memory utilizing processes (child/instance aggregation) now with percentages of total RAM
Prints the top 10 memory consuming processes (with children and instances aggregated) sorted by total RSS and calculates the percentage of total RAM each uses. Please note that since RSS can include shared libraries it is possible for the percentages to add up to more that the total amount of RAM, but this still gives you a pretty good idea. Also note that this does not work with the mawk version of awk, but it works fine with GNU Awk which is on most Linux systems. It also does not work on OS X.

Get your outgoing IP address
should be very consistent cause it's google :-)

highlight with grep and still output file contents

Display current bandwidth statistics
ifstat, part of ifstat package, is a tool for displaying bandwidth and other statistics. The -n option avoid to display header periodically, the -t option put a timestamp at the beginning of the line. Works for me on Debian and CentOS

Download file with multiple simultaneous connections
`aria2c` (from the aria2 project) allows. Change -s 4 to an arbitrary number of segments to control the number of concurrent connections. It is also possible to provide multiple URLs to the same content (potentially over multiple protocols) to download the file concurrently from multiple hosts.

Null a file with sudo
