I need to extract a price from a string, this may vary in the future so it may be 12.99 or 14.99. i thought a sed command might crack it and i need to write to a file:<td><b class="priceLarge">?6.99</b>I need to extract the price 6.99(with no ?)so extract anyhting between "> and </B> and write it to a file such as tmp1.txt .

View 3 Replies View RelatedI need a bash script that can read a file, say example.txt search for the string "This is my example string" and save whatever word/number comes immediately after it to a variable, var.
Example:
blah blah
blah This is my example string extracthere is a very nice word.
blah blah
There are two constraints:1. This needs to assume as little as possible about the nature of the known string "This is my example string" and the word that follows it. I am trying to keep my code adaptable.2. Speed is valuable. This shell will be executed dozens if not hundreds of times so speed is very desirable. I thought I read that some commands are faster than others.

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.
I have a set of lines as ahown below:
Leon went to school
Leon came back from school..
Leon had dinner...
I have to replace the line containing "dinner" by a single string LUNCH...
I need to creates string suffixes out of a Reference string. for eg. suffixes of abcdefg will be
1)bcdefg
2)cdefg
3)defg
and so on...
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 am trying to extract 2 numbers from a same file and my goal is to print them both in another file, on the same line, separated with a space. I have to do that for 20 files and I would like to have therefore 20 lines like this in the output file. It would look like this :
Quote:
number1_file1 number2_file1
number1_file2 number2_file2
...
...
number_1_file20 number2_file20
So far, I did only extract one number and got an output file like this :
Quote:
number1_file1
number1_file2
...
...
number1_file20
And I did this by running a bash script with the following content :
Code:
#!/bin/bash
ls execution$1$2*.* | while read filename
do
cat $filename | grep -e "Total aborts:" | cut -d " " -f3 >> abort$1$2.dat
done
$1 and $2 are just strings to identify the different files I want to consider in this loop. This script works well to extract a number which is the 3rd field of a line starting with "Total aborts:".Now, how could I change this script to do what I mentioned above (i.e. extracting two numbers from two different lines) ? The second number is the 3rd field of a line starting with "Total throughput:"

I have many files in a folder from which I need to extract some contents, these are basically text files wich have individual lines with (i.e)
name: john
address: whatever
phone: 123456
Some caveats
1. Sometimes a line might be missing.
name: johnn
phone: 123456
2. Lines are not in the same line-numbers across the files I did try some things with awk based on google searches but I couldn't extract the data of each file into a single line (this is the ultimate goal):
john,whatever,123456
I don't have knowledge other than having put some bash scripts together for backup jobs, so I am open to install anything that could to pull this off.
I'm trying to create an application that monitors, among other things, what site the user is currently viewing. I would like to know if there is any way to get the current URL from the Firefox's address bar on a Linux machine. I know that under Windows I can use the DDE server approach, but under Linux this task is proving very tricky. I've considered an approach involving an extension to Firefox, but this would require the user to install the said extension himself. Which is not something I want. If an extension can be installed by a different program's installer than that could work, but I don't know if that's possible or not.

I am trying to get the metadata out from an image file in python. I have tried using PIL but it does not give me the data I am looking for (mostly just got a bunch of hex code) and I have no idea how to use ImageMagick, the python module is poorly documented and I can't find any examples on the net.The info I need is stuff like camera model, if flash was used, focal length, exposure time, date, etc.. pretty much the same info I get when I look at the "Image" tab on properties in Nautilus on Ubuntu.
What I am doing is writing a script that will iterate through a lot of pictures and put all this metadata into MySQL. I chose python since it is simple and I am familiar with it. But I can't find a good way to get that metadata from within python.

I've spent most of the evening browsing the web, trying many things I've found on various forums, but nothing seems to work.
I have a test.txt file containing many lines like the following ones :
...
<insert_random_text>228.00 €<insert_more_random_text>
<insert_random_text>17.50 €<insert_more_random_text>
<insert_random_text>1238.13 €<insert_more_random_text>
...
And I want to extract :
...
228.00
17.50
1238.13
...
There is always one occurrence of € in each line. I want the numeric value that precedes this € occurrence. The random text (before and after) may contain numbers too, so the € may be important to parse, in order to correctly identify the number to return. The last character that precedes the number to extract is always a ">" (coming from an HTML tag).
I have a requirement where I want to extract the full name of the process running in my box. I tired various options of ps. The wide option gave me the full command but that contains command, the interpreter and also the arguments passed.

I have a huge file which has 450G. Its format is as below
x1 50020 A 1
x1 50021 B 8
x1 50022 C 9
[code]....
Now, I want to extract a subset from this file. In this subset, column 1 is x10, column 2 is from 600000 to 30000000. I wrote the following perl script but it doesn't work:
#!/usr/bin/perl
$file1 = $ARGV[0]; # Input file
$file2 = $ARGV[1]; # Output file
[code]...
I guess the input file and output file are both too big that my script can't handle it.
A strange question, I guess. I'm running processes called from a c main program. The calling is performed (for now) as: FILE * res=popen(ulimit -t 1; prg args); So I can read the stdout of the process as a file and analyze it. The time limit is important for me.
2 questions:
1. How do I get to know if the process terminated on its own or by the ulimit?
2. How do I limit to times that are less than 1 sec (I have many of those).
I know that setrlimit exists, just before I change my whole approach I wanted to see if I can deal with these things from the outside.
I have a file which has the output as shown below:
