If you want to see your top ten cpu using processes from the browser (e.g. you don't want to ssh into your server all the time for checking system load) you can run this command and browse to the machines ip on port 8888. For example 192.168.0.100:8888

Accepts multiple files via logs.... Substitute "text to grep" for your search string.

If you want to alias this, you could do something like this:

alias parse-logs='awk "/$1/{print \$1}" ${@[@]:1} | sort -n | uniq -c | sort -rn | head -n 100'
awk '/text to grep/{print $1}' "log" | sort -n | uniq -c | sort -rn | head -n 100

Original command: cat "log" | grep "text to grep" | awk '{print $1}' | sort -n | uniq -c | sort -rn | head -n 100

This is a waste of multiple cats and greps, esp when awk is being used

cat "log" | grep "text to grep" | awk '{print $1}' | sort -n | uniq -c | sort -rn | head -n 100

You have an external USB drive or key.

Apply this command (using the file path of anything on your device) and it will simulate the unplug of this device.

If you just want the port, just type :

echo $(sudo lshw -businfo | grep -B 1 -m 1 $(df "/path/to/file" | tail -1 | awk '{print $1}' | cut -c 6-8) | head -n 1 | awk '{print $1}' | cut -c 5- | tr ":" "-")

Reads n lines from stdin and puts the contents in a variable. Yes, I know the read command and its options, but find this logical even for one line.

A bitcoin "brainwallet" is a secret passphrase you carry in your brain.

The Bitcoin Brainwallet Exponent Calculator is one of three functions needed to calculate the bitcoin PRIVATE key. Roughly, the formula is exponent = sha256 (passphrase)

Note that this is a bash function, which means you have to type its name to invoke it.

You can check the accuracy of the results here http://brainwallet.org

Feel free to put this in your ~/.profile:

random(){ cat /dev/urandom | env LC_CTYPE=C tr -dc $1 | head -c $2; echo; }

Then use it to generate passwords:

random [:alnum:] 16

Or DNA sequences:

Download latest NVIDIA Geforce x64 Windows7-8 driver from Nvidia's website. Pulls the latest download version (which includes beta). This is the "English" version. The following command includes a 'sed' line to replace "english" with "international" if needed. You can also replace the starting subdomain with "eu." "uk." and others. Enjoy this one liner! 1 character under the max :)

Avoiding a for loop brought this time down to less than 3 seconds on my old machine. And just to be clear, 33554432 = 8192 * 4086.
