This is a safest variation for "sitepass function" that includes a SALT over a long loop for sha512sum hash

Even shorter. Stolen from comment posted by eightmillion.

echo `cat /dev/urandom | base64 | tr -dc "[:alnum:]" | head -c64`
2010-12-06 21:04:57
User: Dereckson
Functions: echo head tr

The same command, but with a base64 filter, more forgiving for special characters than tr.

echo `cat /dev/urandom |tr -dc "[:alnum:]" | head -c64`
cat file | tr -d "\n"
2010-12-02 09:22:02

Functions: cat file tr

This command deletes the "newline" chars, so its output maybe unusable :)

cat file | tr "\n" " "

User: uzsolt
Functions: cat file tr

It's works only when you replace '\n' to ONE character.

Of course, this command must be executed at a GRID User Interface

lhcb - name of your VO, substitute it with the one you are interested it.

This command is primarily going to work on linux boxes.

and needs to be changed, for example



tr '\000' '\377' < /dev/zero | dd bs=512 count=200000 status=noxfer | pipebench | sudo dd of=/dev/sdx
2010-08-31 15:38:27
User: Gliktch
Functions: dd sudo tr

Note: Replace 200000 with drive bytes/512, and /dev/sdx with the destination drive/partition. ;)

Note: You may need to install pipebench, this is easy with "sudo apt-get install pipebench" on Ubuntu.

The reason I hunted around for the pieces to make up this command is that I wanted to specifically flip all of the bits on a new HDD, before running an Extended SMART Self-Test (actually, the second pass, as I've already done one while factory-zeroed) to ensure there are no physical faults waiting to compromise my valuable data. There were several sites that came up in a Google search which had a zero-fill command with progress indicator, and one or two with a fill-with-ones command, but none that I could find with these two things combined (I had to shuffle around the dd command(s) to get this to happen without wasting speed on an md5sum as well).

For reference, these are the other useful-looking commands I found in my search:

Zero-fill drive "/dev/sdx", with progress indicator and md5 verification (run sudo fdisk -l to get total disk bytes, then divide by 512 and enter the resulting value into this command for a full wipe)

dd if=/dev/zero bs=512 count=<size/512> | pipebench | sudo tee /dev/sdx | md5sum

And this command for creating a file filled with ones is my other main source (besides the above command and man pages, that is - I may be a Linux newbie but I do read!):

tr '\000' '\377' < /dev/zero | dd of=allones bs=1024 count=2k

Hope someone finds this useful! :)
