what i am trying to do is to allow the user to key in data such as "23.23" or "24" , as it is the price of certain objectsHow am i able to design a check which will allow me to prevent users from typing in input such as "ab.21" or "rfrr" as this field is purely a numerical field. The problem i am facing is i tried using this search code.
Code:
echo "read this"
read this

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");

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 am trying to do a search to check if the input is using alphabets and nothing else.
I tried using [[:digit:]] and [[:alpha:]] but none seems to work
When i use digit, it read 22.k as alphabet and not as a wrong syntax.
For alpha , it does not allow me to input data which has spaces such as " hello world".

I am trying to figure out how i would go about finding out where system call is made and error checking is not done. I have code below, if somebody can point me in the right direction where system call is made but error checking is not done.Quote:

I need to allocate a % of the total system memory for a buffer but what is the best method to determine how much memory is in the system? So far the only way I have found is to get the pages of memory:
Code:
long sysconf(_SC_PHYS_PAGES)
Is that the only option?

But, is there any possibility to check without our login?(not even by ssh)
Our logging in to find that pc, will be wasting the cpu resources. And may disturb the user who is working on the x-session.
I am trying to do a search for the certain books, and I am trying to make it case insensitive. what I have come up with so far is this :
Code:
Database.txt
RETARDED MONKEY:RACHEAL ABRAHAML:30:30:20
GOLD:FATIN:23.20:12:3
StUPiD:JERLYN:20:40:3
Code:
echo -n "Title: "
read Title
echo -n "Author:"
read Author
echo ""
valuecheck='grep -i "$Title" Database.txt | grep -i "$Author" | awk -F":" '{ print $1}''
echo $valuecheck
if [ $Title = $valuecheck ] ; then
echo "HOHOHO"
else
echo "too bad"
fi
The issue which I am having is that, when it does the search for the correct row to be inputted into valuecheck, it will input the value as written in the database, which is in Uppercase. For this case, if I type in stupid for $Title and jerlyn for $Author, it searches the correct row, but the awk will print "STUPID" into the variable as that is what is written in the database. So how can I make my if statement case insensitive? Currently it reads like this:
Code:
if [ $Title = $valuecheck ] ; then
which means
if [stupid = StUPiD ] ; then
How can I make the if statement it case insensitive to allow it to display "HOHOHO"
i am searching a string(with multiple words) in a file that file contains the string but words are separated with multiple white space.
ex: pattern to be matched "hello how are you" all single white space and file contains " hello how are you" variable white space between words
grep "pattern" file_in_which_to_search i am reading the "pattern" so i cannot modify the "pattern"
so my pattern match does not take place, though i want it to match.
I'm trying to figure out a simple script to go thought 500 Cisco devices to see if I can SSH to the device. Then display something like this:
10.0.0.1 Yes
10.0.0.2 No
10.0.0.3 No
I tried something like this:
Code:
ssh -q -o BatchMode=yes -o StrictHostKeyChecking=no user@10.0.0.1 "echo 2>&1" && echo "Yes" || echo "No"
When tested the above line it replied No, even if I tried it on a Switch that does not have SSH configure.

I need to check whether a shell script variable contains non-zero numeric data to proceed. The variable should contain numeric values, but may in fact contain zeroes, blank space or nothing. So far, I have tried various combinations of:
Code:
if test $variable
then
if test $variable -gt 0
then
echo "good data exists"
else "no good data exists"
fi
fi
It partially works, but I get either "too many arguments" or "integer expression expected".
I get this:
0000000 1202 0 0 0 0 0 0 0
0000020 141 89 63 89 141 0 0 0

Sometimes at startup I get this message "Checking disk 1 of 1". Does that mean it's checking all partitions on the hd? After a bad shutdown there is no prompt for fsck to run and the system just boots up. In fstab I have both options set to "1" for the partition Ubuntu is on, all others set to "0". Any ideas on both?

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 ?
I want to count the digits in between the text in a file.

Then read this.
How can i do the counting of these digits present in between a text in a file?
As i am new to C++ i couldn't figure out how to input a file and make some change on the file and produce a output file. like this problem i have is.
"Program that processes an input file and produces an output file. The input file will contain lines of data, each containing two floating point numbers. The lines of the output file should contain the two numbers read and their average (with a '$' sign and 2 places after the decimal point)."
I've done a little program, it's the snake game. I use an X window to show the snake and all that but the input is taken from the terminal. That means that what I have to do to play the game is open it with the terminal and then the game opens but then I have to go to the terminal again to move the snake. if I open the game from the GUI I can't do anything because it doesn't take my directions. What do I have to do in order to get the program to have a connection with my keyboard? I use getchar() to get the input, maybe there is something else?
