5 Mins of googling and I found this site. I am blantantly copying and pasting the post, this is NOT my post.

Date of yesterday in bash?
I recently had to hack a small shell script that would read files in a directory structure generated based on the date, something like 2007/08/16. The trick was that the script would look at yesterday’s file or files generated a few days ago.

A quick search on info and here’s the magic command

FILE=”…$(date -d ‘yesterday’ +%Y/%m/%d)”
Interestingly, you can also use things like 3 days ago, next Monday, 2 months etc. Cool!

So, I went googling and found this post which linked to this which has this snippet of code:

ic = Iconv.new('UTF-8//IGNORE', 'UTF-8')
valid_string = ic.iconv(untrusted_string + ' ')[0..-2]

This block of code did the trick. It basicly removes invalid UTF8 characters. I can’t say that I took the time to fully understand it, I just know that it works.

find . -iname '*.jpg' | sed "s/ /\\\\ /g" | xargs du -ksb | cut -f1 | xargs echo | sed "s/ /+/g" | bc

That does it Breaking this monster down gives us the following.

First cd to the directory you want to check in.
cd Pictures

List the files. find finds files.
find . -iname '*.jpg'
./Picture3 001.jpg
./Picture3 002.jpg
...
./Picture4 099.jpg


List the files, excaping spaces. sed allows you to perform actions against the string being passed to it.
find . -iname '*.jpg' | sed "s/ /\\\\ /g"
./Picture4\ 001.jpg
./Picture4\ 002.jpg
./Picture4\ 003.jpg
...
./Picture4\ 099.jpg


List the files, getting file size. xargs allows you to take a line of input and execute it. du is used to get the disk usage size.
find . -iname '*.jpg' | sed "s/ /\\\\ /g" | xargs du -ksb
696009 ./Picture4 001.jpg
675879 ./Picture4 002.jpg
666862 ./Picture4 003.jpg
...
658225 ./Picture4 099.jpg


Cut the file size out of the listings. cut -f1 gives us the first field using ‘space’ as a delimeter.
find . -iname '*.jpg' | sed "s/ /\\\\ /g" | xargs du -ksb | cut -f1
700696
702453
703594
...
696009


Take all of our lines of file sizes and concatenate them to a single line.
find . -iname '*.jpg' | sed "s/ /\\\\ /g" | xargs du -ksb | cut -f1 | xargs echo
700696 702453 703594 ... 696009

Replace the spaces in our single line with ‘+’.
find . -iname '*.jpg' | sed "s/ /\\\\ /g" | xargs du -ksb | cut -f1 | xargs echo | sed "s/ /+/g"
700696+702453+703594+ ... +696009

Now take the output above and use bc to calculate it. bc is a simple command line calculator.
find . -iname '*.jpg' | sed "s/ /\\\\ /g" | xargs du -ksb | cut -f1 | xargs echo | sed "s/ /+/g" | bc

How big are all the jpg files in my pictures directory? 54,631,548 bytes.

So, command line? Pain in the ass to get something so simple, but pretty awesome that there are so many different, tiny programs for *nix that can work together to get you the results you want.

Fairly simple setup:

1. Log into your shell (doesn’t matter if its Cygwin or a standard Linux distro)
2. Change to the .ssh directory
   $ cd .ssh

3. Generate the private/public key pair (use defaults, including the password, unless you wish to still type in a password on each connect)
   $ ssh-keygen -t dsa
   Generating public/private dsa key pair.
   Enter file in which to save the key (/home/[username]/.ssh/id_dsa):
   Enter passphrase (empty for no passphrase):
   Enter same passphrase again:
   Your identification has been saved in /home/[username]/id_dsa.
   Your public key has been saved in /home/[username]/id_dsa.pub.
   The key fingerprint is:
   aa:d3:81:89:31:13:01:7c:80:d8:e5:4d:90:b1:25:a6 [username]@[hostname]

4. Transfer the file to the remote machine you wish to use the key to log into
   $ scp id_dsa.pub administrator@192.168.111.45:./id_dsa.pub

5. SSH to the remote machine
   $ ssh [remoteusername]@[remotehostname]

6. Touch the authorized_keys2 file, just in case it doesn’t exist yet
   $ touch ~/.ssh/authorized_keys2

7. Set permissions on the authorized_keys2 file so that only the owner can read/write to it
   $ chmod 600 ~/.ssh/authorized_keys2

8. Copy the contents of the public key into the authorized_keys2 file
   $ cat id_dsa.pub >> ~/.ssh/authorized_keys2

9. Delete the public key file, just because it’s safer that way!
   $ rm id_dsa.pub

10. Logout of the remote server
    $ exit

11. SSH back into the remote server and test to see if it asks you for a password (assuming you did not enter a password while generating the keys earlier)
    $ ssh [remoteusername]@[remotehostname]

Now you can ssh from your machine to the remote machine without using passwords but still keeping the remote machine secure.

$('#tableid tbody tr:odd').addClass('tableodd');

Super simple, yet that wouldn’t work, because there are 2 table rows per result.  I did some googling and found this, which was pretty close to what I needed. In the end, I modified the code found on that page a bit and ended up with the following at the end of the function that actually populated the results table.


var classNames = {
0: '',
1: '',
2: 'tableodd',
3: 'tableodd'
}

$(‘#tableidtbody tr’).not(‘[th]‘).each(function(index) {
$(this).addClass(classNames[index % 4])
});

Works great.  If you need to add any additional rows to your result, then just add another row to classNames and change the index % 4 to how ever many items you have in your classNames array.

Hope someone else will find this useful.

Sweet! Oh ya, I got to install Visual Studio 2008. No problem, I’ll grab my copy of my file server and install it.  LOLWUT? Can’t copy file 67 of 71? Fine, I go find another copy.  2 hours later, it’s installed.

Time to install Sql 2008 Express.  Run setup. Wut? .Net framework 3.5 needs to be installed.  I thought that came with Visual Studio 2008? Anyway, download it and install it.  Rerun Sql Express setup.  Now I gotta have Windows Installer 4.5.  WTF? Just install! So, download that and install it.  Run Sql Express setup AGAIN. OMFG! I need Visual Studio 2008 Service Pack 1 installed! FINE. Download it, run it.  Wow, it took 50 minutes to install the damn service pack.  Funny, installing THE ENTIRE DAMN VISUAL STUDIO APPLICATION BUNDLE TOOK 20 MINUTES, but a service pack takes 50?

Nice going Microsoft.  What should have taken no longer than an hour has now taken me damn near 5.
