With array in php. All I was having the following columns:
Code:
Now Like the Above there were more variables defined through script:
Code:
Now what the above code is doing is calculating average of above values from columns{1-?,4-?)..likewise
Say If I remove two Machine and calculate the avg.
I'm trying to write a python script that will calculate my test scores from a text file named "exams."
Sample input would be:
Output will look like:
I have the following code:
Code:
My intent is to sum the values found in L and divide by len(L).
I think my issue is that when I split the values, I get a string array (ex. ['85', '90'] ), which makes it hard to do calculations.
I have a data in a column.
Code:
I want to calculate average and standard deviation. As first step I want to calculate average for the data than calculate (del=data - avg) for all the data.
I suppose get
Code:
For this I use AWK and the code goes like this
Code:
But I get different answers.
Code:
Why the answers are so different? since this is wrong I can not continue calculating the standard deviation.
I have an array called arrayini which stores numbers. I want to take log to the base 2 of each of the numbers in that array and put it in file called result. I've used the following code to do it.
Code:
size=${#arrayini[@]}
for ((i=0;i<size;i++))
do
echo "scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >result
It works fine but its taking pretty long to calculate since I've got about 230,000 items in the array. So I decided to store the result into an array hoping that it'd be faster. I tried the following code. arrayresult is where I try and store the result. The code doesn't work because of the second last line.
Code:
unset arrayresult
size=${#arrayini[@]}
for ((i=0;i<size;i++))
do
arrayresult[$i]="scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >FILE2
There is a syntax error clearly.
I am new to shell script and to this form as well, I did try to search for a similar post like mine here, but could not find one.
Here is what I'm trying to do:
I am trying to grep server logs to find a specific string and then capture the time stamp and the value of that grep string in them. The log file prints out messages on per sec basis.
My script is able to grep the server logs for the entire period of my load runs and then outputted it to a .csv file too.
Unfortunately this .csv file is too large to extract it on my PC and to generate graphs as it exceeds the excel limit. I need some help on how to read this .csv file in a shell script and then take an average on per min basis before I can export it out on my desktop and generate graphs for analysis. example of the out in my .csv file:

I'm writing a PHP program. I've encountered a problem; in the following code I try to pass $_POST['delete'] which is an array as the value of a hidden input to some form, but it doesn't do so.there's something wrong with converting PHP array into HTML array. I'm sure that $_POST['delete'] is not null and is a real array.
echo '<input type="hidden" name="delete[]" value="'.$_POST['delete'].'" />';
I have a text file with 4 columns and 18 rows. All are integers. I wish to find the average of first 12 numbers in the third column using 'awk'.

how can I read the file, sum the numbers ( "avoid" the #lines) and then get the average of the numbers?
I do awk '{s+=$0} END {print s}' /tmp/file.txt. and this give me the sum correctly, but how can I get also the average ?

I'm new to the linux world and its been quit sometime since i've done any programming. However, I'm writing a program which simply calculates the load average of a process. In doing this I need to use the uptime command for linux in a java program. I've done a little bit of searching on the net and it mentions this is possiable by using java runtime command. Unfortunatly though I have yet to find a working example of this. I've tried just simply reading the /proc/uptime file but I have no clue how to format the 2 numbers in seconds to make it the same as if you just typed in uptime in the linux command prompt.

I have a text file from which i read a number of names with their lengths at the run-time.Now i want to created a char array having the length and name as already read from the text file at the run-time. There is no compilation involved. Every thing is happening at the run-time. I tried using STL like map along with malloc but i am unable to name an array at run-time. I can keep some type of mapping with previously created arrays

i have a loop which produces new value everytime it runs. i want to store the results in an array. how can i do dat??
loop is like:
a=0
declare v
while ((....))
do

let a=a+1
done
while doing this it is not treating v as array but as variable and it is overriding the value and old value is lost..i am using bash shell version 3.00.15
Here is statement.

$1 is an argument which is actually and array. In function we want to assign a value 0 of it's first content. But it's wrong way. Anybody know the right way to assign value in function by passing as argument.
Is it possible to have an array in Bash that can hold more than one value per item?
For example I would like an array like this:
Entry 1: apple, green
Entry 2: banana, yellow
And be able to call the fruit names and their colour in a list. Something like:
for fruit in "${array[@]}"
do
echo a $fruit is $colour
done
If that is possible, is there a limit to values per item? For example some entries in an array could be:
Entry 1: apple, green, round, pips, tree
Entry 2: banana, yellow, long, skin, tree
And I would like to pick out the values such as #3 being "round" and "long".
I believe I have unwanted ' characters left in a 9 element character array that are causing subsequent operations with it to fail.
