None of my daemon scripts work now, and the startup process displayed errors. Should I reinstall the OS and start from scratch, or is there a way to recover these files? Is there a way to rebuild the files I deleted?

I have a file of words and want to encode them in a numeric form, based on position.This is best explained by example:
PEOPLE ==> 123152
Reading left to right:
P was first encountered at position 1 so it is encoded as 1.
E was first encountered at position 2 so it is encoded as 2.

I have a hp mini 1033cr. Awhile ago I installed ubuntu netbook edition, well I was new to Ubuntu so I clicked upgrade. Well everything was going good and then it restarted. when I came up to the log in page I typed my password and now it won't boot. it goes to the desktop theme but then freezes with three warning messages.
1st could not update ICEauthority file /home/adam/.ICEauthority
2nd There is a problem with the configuration server. (/usr/lib/libgcond-sanity-check-2 exited with status 256)
3rd Nautilus could not create the following required folders: /home/adam/desktop, /home/adam/.nautilus
I have tried a fresh install with a disc I burnt and ran with my external dvd drive. Well guess what it decided to not boot from it. I have also tried several other discs including a windows xp disc. it always boots back to the hard drive.

Is there a limit to the number of partitions/logical volumes you can create using the partman-auto recipes? If not, any thoughts on why my preseed using the values included below results in only a /boot partition and logical volumes root, swap, and user? Is there another way to achieve putting /, /tmp, /var, /usr, /usr_local /opt, etc on their own logical volumes with preseeding?

Using PHP 5.x. I would like to sort a set of values first numerically, then alphabetically. For example, here's my code so far:
Code:
<?php
print "<p style="font-family:verdana;font-size:10pt">
";
$myArray = array("1223:starfruit", "34112:oranges", "1223:zucchini", "321:apples", "34112:pears", "1223:tomatoes");
[code]....
I have fiddled with array_multisort but I can't seem to get my head around it or the many sort routines in PHP.

I just received a spreadsheet. Column B contains thousands of rows that look like this:
Giant Red Pencil 0.99
Case 2.99
Green Box 1.49
Ruler 0.59
Spiral Ring 0.10
So each cell contains the item and price. I need the corresponding cells in column C to contain only the price like this:
0.99
2.99
1.49
0.59
0.10
How do I extract just the price from column B and put it in column C ?

Code:

#Functions
CallFunct() {
functio()
[code]....
When I try to run the current code, it stops on the bracket after functio() in CallFunct(). The only way I could get this to run was by removing CallFunct and just calling functio.

In my code I want to have two different functions to be executed simultaneously (in parallel) in a single processor system. I tried to use pthreads but they happened to be executed one after another. I have heard about fork, some saying that its no longer recommended since its functions can be achieved by pthreads.

#export file_name= "&1"
[Code]....
my problem is that when i execute this script only the first two functions are being called.once the DBcounttry_finalnofunc() is done ,the script exits.The rest of the functions are not being called.

In shell scripting, what do or what does this symbol do or mean ? "."(octet), ";" (semicolon)? Would really like to know? Cause I saw a written script if [ -f /etc/file ];then. . /etc/file. Wondering, the "." is meant to be source, so is "." the same thing as "source" ?
