This snippet will produce an alpha-numeric 16 character password

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 ":" "-")

Sort netflow packet capture by unique connections excluding source port.

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

Then use it to generate passwords:

Or DNA sequences:

displays a list of all file extensions in current directory and how many files there are of each type of extension in ascending order (case insensitive)

This lists the number of ogg/mp3/wav/flac files in each subdirectory of the current directory. The output can be sorted by piping it into "sort -n".

Uses urandom and tr to generate a random password. Change the value of head -c## for the lenght of the password.

Opposite:

Convert an one-liner to script:

I did not come up with this one myself, but found this somewhere else several months ago.

Usage: t2s 'How are you?'

Nice because it automatically names the mp3 file up to 15 characters

Modified (uses bash manip instead of tr)

t2s() { wget -q -U Mozilla -O $(cut -b 1-15

My first command :) I made this command to log public addresses of a virtual interface who connects random VPN servers around the world.

Took one of the samples, added capitalization and removes in between spaces.

The final "echo" is just for readability.

Replace $USER with the username of the Reddit user in question. To get comment karma instead run...

make usable on OSX with filenames containing spaces. note: will still break if filenames contain newlines... possible, but who does that?!

This line unbuffers the interactive output of rsync's --progress flag

creating a new line for every update.

This output can now be used within a script to make actions (or possibly piped into a GUI generator for a progress bar)

It will produce passwords with length of 20 printable characters within a reasonable time.

For shorter or longer passwords just change the 20 in bs=20 to something more convenient.

To create only alpha numeric passwords change [:print:] to [:alnum:]

Used in OS X.

tr "\n" ";"

may be replaced by

echo ";"

with linux versions of date.

This is just a proof of concept: A FILE WHICH CAN AUTOMOUNT ITSELF through a SIMPLY ENCODED script. It takes advantage of the OFFSET option of mount, and uses it as a password (see that 9191? just change it to something similar, around 9k). It works fine, mounts, gets modified, updated, and can be moved by just copying it.

USAGE: SEE SAMPLE OUTPUT

The file is composed of three parts:

a) The legible script (about 242 bytes)

b) A random text fill to reach the OFFSET size (equals PASSWORD minus 242)

c) The actual filesystem

Logically, (a)+(b) = PASSWORD, that means OFFSET, and mount uses that option.

PLEASE NOTE: THIS IS NOT AN ENCRYPTED FILESYSTEM. To improve it, it can be mounted with a better encryption script and used with encfs or cryptfs. The idea was just to test the concept... with one line :)

It applies the original idea of http://www.commandlinefu.com/commands/view/7382/command-for-john-cons for encrypting the file.

The embedded bash script can be grown, of course, and the offset recalculation goes fine. I have my own version with bash --init-file to startup a bashrc with a well-defined environment, aliases, variables.
