Check These Out

Set laptop display brightness
Run as root. Path may vary depending on laptop model and video card (this was tested on an Acer laptop with ATI HD3200 video). $ cat /proc/acpi/video/VGA/LCD/brightness to discover the possible values for your display.

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"

Enable ** to expand files recursively (>=bash-4.0)
Since bash 4.0, you can use ** to recursively expand to all files in the current directory. This behaviour is disabled by default, this command enables it (you'd best put it in your .profile). See the sample output for clarification. In my opinion this is much better than creating hacks with find and xargs when you want to pass files to an application.

check open ports (both ipv4 and ipv6)

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

Netstat Connection Check
This command does a tally of concurrent active connections from single IPs and prints out those IPs that have the most active concurrent connections. VERY useful in determining the source of a DoS or DDoS attack.

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"

Google Translate
Usage: $ translate Example: $ translate hello en es See this for a list of language codes: http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes

Append last argument to last command
Just like "!$", except it does it instantly. Then you can hit enter if you want.

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.
