I think read A1 A2 makes A1, A2 string variables. Then, when A2 gets the value 01, '01' should be a string. But for some reason bash takes it as numeric. I know there are no types in bash.
I'm trying to display fields from flat files where the first 8 fields are always the same. Fields 9 - n are varied but will contain specific patterns I'm after. I'm using this so far because "mySearch" is on each line I want to examine.

How would you pattern match and include 2 additional fields above field $9 but change field position from line to line?

I am creating a game with random variables. In the game I have created a dialogue exchange to players. I have set up a table with various returns and I inserted {$fields} to represent various random variables. When I call on the requested fields, I only see the field text and my field names. Am I supposed to parse something and call it back another way?
ie: myfield is: "You have won {$random1} silver! <br />{$wi['gender'] majesty rewards you well." the code I am using to call that field is:
copy string a to string b and change string b with toupper() and count the chars

I've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.
[Code]....
One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?
Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.

create an array of pointers to point to the first few characters and then use that pointer to print the rest of the string.But when i print using the pointer i get GARBAGE values! shudn't std::cout<<ptr[w] print the string following the char it is pointing to? why do i get garbage values?
So if I'm given a location of a file like:
How can I just take the type of the file at the end? I know I can use strrchr() for a period to get the pointer to the period just before file type. Is there a build in string function that will just take the rest of the string from a certain point on forward in the string? I know it wouldn't be much work to make it myself, but I figured I would find out if it already existed before doing it.

I've had a very colorful morning learning the innerparts of Linux's sort command, and have come across yet another issue that I can't seem to find an answer for in the documentation. I'm currently using -t, to indicate that my fields are split by the comma character, but I'm finding that in some of my files, the comma is used (between double-quotes) within values:
Jonathan Sampson,,foo@bar.com,0987654321
"Foobar CEO,","CEO,",ceo@foobar.com,,
How can I use a comma to terminate my fields, but ignore the occurences of it within values? Is this fairly simple, or do I need to re-export all of my data using a more-foreign field-terminator? (Unfortunately, I do not have any control over declaring a different terminator with this particular project).
I've been given a custom-made string class which handles string, wstring and bstr. It has a number of methods and assignment operators to convert to and from different types. The app I work on compiles happily in VS6 and VS2008, but when trying to compile in Redhat (version 4.1.1 in Redhat 5.0)

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"

It partially works, but I get either "too many arguments" or "integer expression expected".
I want my bash file to read from "input.dat" the two values emin emax. My input file looks like that:
#cat input.dat
!Energies
emin 10.00 !minimum energy
emax 30.00 !maximum energy
Now this seems to be not so hard with the command awk
#!/bin/bash
awk '{FS=" "}/emin/{print $2}' input.dat
awk '{FS=" "}/emax/{print $2}' input.dat
[code]....
So far so good. Now, I want to define two variables (e.g. e1,e2) in the bash file, so that their values would correspond to 00.00 and 30.00, as read from the input file. This one I have not found yet, thus asking for your advice. At the end, writing echo $e1 $e2, I should get 10.00 30.00 This is even harder to me: I want to replace the values emin,emax in a new file "modify.dat" which looks like that:
...
c---- energy interval
emin = 1.00
emax = 2.00
...
with the values e1 and e2 I have in my bash file. In other words, I want to call "modify.dat", find these two lines and replace the numeric values with the e1 and e2. At the end, my file should be like:
...
c---- energy interval
emin = 10.00
emax = 30.00

I want to validate a web form using PHP. I spent ages confusing myself with client side scripting and realised until I worked out it is not what I want. My problem is that now I am looking at PHP and everything is mixed up in my brain. I need to point out that PHP is very new to me! This is what I already have:
1 An html page with my form on it.
2 PHP page which emails the contents of the form to me.
The above works well. For the sake of clarity, here are my pages (cut down to the essentials where appropriate): My html form:
first name surname
Email
Home phone
Mobile
Work phone
I have read and understood your terms and conditions. My php script (regform.php)
$receiver = 'me@email'; $subject = 'New registration'; #$message = 'This is a new registration.'; $surname = $_POST['surname']; $firstname = $_POST['firstname']; $address = $_POST['address']; $email = $_POST['email']; $homeph = $_POST['homeph']; $mobileph = $_POST['mobileph']; $workph = $_POST['workph']; $time = $_POST['time']; #from here $oldaddress = $_POST['oldaddress']; $DOB = $_POST['DOB']; $elect = $_POST['elect']; $job = $_POST['job']; $salary = $_POST['salary']; $employer = $_POST['employer']; $benefit = $_POST['benefit']; $smoke = $_POST['smoke']; $claim = $_POST['claim']; $children = $_POST['children']; $children2 = $_POST['children2']; $pets = $_POST['pets']; $pets2 = $_POST['pets2']; $require = $_POST['require']; $terms = $_POST['terms']; $rooms = $_POST['rooms']; $body = "first name:$firstname

You can see there are many more form fields than I have shown in my example html form above. What I want is that the following fields have to be filled:
1 mobileph
2 email
3 terms (checkbox)
I would like the user to be asked to fill the form in properly if any/all of the 3 fields have not been filled in. I imagine I need some php in the html page and some more in the php page. I am certainly not asking any one to do this for me but I am really confused. I have googled and copied and pasted and edited for 6 hours and I am lost. What I want is a very simple and clear example of the code needed. Sorry if I sound as if I can't search properly on Google: in this case I clearly can't!
I'm having a bit of a trouble getting a particular field replaced in a host list. I have a MasterHostList which has a comma delimiter for fields and a new line to separate servers.
server1,random,random,group1,random,random
server2,random,random,group1,random,random
I then have a file.list file with a grouping of server names. What I need is to search the MasterHostList and for each server that is in the file.list I need to change the fourth field from group1 to group2 without changing the order or position of anything in the MasterHostList. Obviously the above names are arbitrary.
Failed attempts have been: for SERVER in `cat file.list`; do sed /$SERVER/s/,group1,/,group2,/ MasterHostList MasterHostList.tmp && mv -f MasterHostList.tmp MasterHostList; done for SERVER in `cat file.list`;do awk 'BEGIN { FS=OFS="," } /^${SERVER}/ { $4 = "group2" } 1' ./MasterHostList MasterHostList.tmp && mv -f MasterHostList.tmp MasterHostList; done
Both of these would in various output tests find the correct lines, but it wouldn't change them all correctly.
I have a file with variable length lines containing fields separated by colons:
Code:
path/to/file0.c:4150:109:4151:142:4153:275
path/to/file1.c:4040:109
path/to/file2.c:4605:72:4606:109
path/to/file3.c:4380:54
The first field identifies the file name, the second is the search key, and the third is the line number of the file that the search key points to. Any subsequent fields are other key/line number pairs.
As an example, I can search for 4151 (key) from my bash script to identify the file I will have to access, but I also need to capture the line (142) as well, and I can't figure out how to do that using grep, awk or sed (or anything else).
If I have a MySQL field called, say, "Occupation", which contains "Java Programmer" in it, I would like it to come up when I search for "Java", so that I can get to the other fields in the table.
How do I do this?
In the MySQL database for one of my programming projects, I used a "YEAR(4)", because I wanted the column to contain four-digit year values. I discovered, though, that this type only allows values from 1901 to 2155, which is not workable as some year values are previous to the twentieth century. But I do not want a "DATE" type because the month and day are of no interest to me. What type should I convert to that would be the least radical change in data type, while giving more range?

View 1 Replies View RelatedI've got a set of objects (all of the same type). I'm trying to think of a good way to divide it into equivalence classes, with equivalence of two objects defined as meaning a specified set of attributes are equal for both objects. More concretely, I've got:
- a Java class with around 50 fields
- a bunch of instances of the class
I want:
- to divide the instances into a few sets
- in each set, each instance has field 1 - field 5 equal to fields 1-5 of the other instances in the set.
The method I've come up with is to generate a hashcode for each instance based on the hashcodes of fields 1-5*, and map the hashcode to one of my sets. Ignoring problems with potential hashcode collisions (which I'm expecting to be too rare to worry about for now), does that sound reasonable? It seems simple enough, but I'm wondering if there's a simpler method I haven't thought of.
* I'll generate the hashcode using a method based on Eclipse's generic hashcode method, which looks like this:
Code:
public int hashCode() {
final int prime = 31;
int result = 1;
