how do I achieve the result but here is the story. I have a script which prompts for the IP Address and read that value and validate if reachable. If not then it should keep on prompting until the IP is reachable. I tried using until loop as well as while loop but dang..Here are the codes
#!/bin/bash
IP_Feed () {

I am querying a single string column in a table. The string values have spaces in them. I want to loop over each value in bash. I set IFS to split lists on newlines instead of spaces. When I try this, it is splitting the list of results on the actual character 'n', not the newline ''.
DATA=`mysql -u root -ppassword --silent 'SELECT name FROM table_a;'`
IFS=$'
'
for i in $DATA; do
echo "item = $i"

How can I achieve file consistency while using mmap? I have a block of code that needs synchronized access across processes (not threads). Using threads, one can regulate access to the mmaped portion of the file by locking it using a mutex. How can I achieve the same using different processes, some of which run in different programs?

There is a protocol in use - for example when I use Firefox to do a query through Google - as I type into the search field the browser sends my characters - one at a time - to the server. As I recall, at one time I found the specification but I'm pulling a blank. As I recall it does a POST of each character as I enter it, and the server responds before I have entered a <CR>. I want to write a client side program that uses that protocol and need to see the spec.

What is the code snippet required to get an image to repeat vertically up a page? I can only find info relating to repeating *background* images in my search attempts, and this is just a regular image file which I want to repeat over the pre-existing page background. I'd like it to repeat all the way up the extreme left hand edge of the page. Say the image is called abd.jpg and is in the same folder as the index.html.

I am not sure if this is possible. I have IP's stored in a mysql database. When I query the database, it returns the IP. I would like to replace the IP with something else prior to displaying the results. Is it possible even though I have not stored it in the database?
I have the following in a while loop (mysql_fetch_array).
Code:
<td align="left">' . $row[IP] . '</td>
Instead of displaying $row[IP] from the database, I would like it to display something else which I define in the PHP code but based on the IP.
ie. aaa.bbb.ccc.ddd = hostnameABC
So I've got a rather vast database, one of the columns is date in the following format: DD/MM/YY HH:MM:SS. This is starting to cause problems with a php page I'm writing which asks the user for a 'start date'. Would it be better for me to split the date column into date and say time? Or is there a way of using distinct and masking the times.

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

View 5 Replies View RelatedI have a socket library that I tinker with from time to time. Lately, I decided to expand it to support IPv6.
One of the issues I am having is sending data, using sendto(). When the server receives data from a client, using recvfrom(), it does not retain the sockaddr_in information, but instead provides the callee the IPv6 address and port number from where the data originated. See here:
Code:
int
UDPSocket::recv(char* buffer, size_t bufferLen, std::string& sourceAddr, unsigned short& sourcePort)
{
sockaddr_in sin;
