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.

I reused

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.

This was tested on Ubuntu 12.04 (Precise) LTS Server. It returns the name of the symlink within /dev/disk/by-id for the physical drive you specify. Change /dev/sda to the one you want, and replace ata- with scsi- or the appropriate type for your drive.

I used this to pre-configure grub-pc during a non-interactive install because I had to tell it which disk to install grub on, and physical disks don't have a UUID such as that blkid provides.

Remove empty lines additionally:

tr -s ' \t\n' <1.txt >2.txt

identical with:

tr -s '[:space:]' <1.txt >2.txt

To "clean perfectly" a text or code file, You can combine this command with

another one:

while read l; do echo -e "$l"; done <1.txt >2.txt

(= remove all leading and trailing spaces or tabs from all lines of a text file)

Not always does Xorg run on :0. For times like those, this script allows you to find out which it is.

tr has some predefined sets of characters that are more convenient to use than characters codes

cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 18 | head -1 | python -c "import sys,crypt; stdin=sys.stdin.readline().rstrip('\n'); print stdin;print crypt.crypt(stdin)"
