I want to copy files from an incoming directory, but don't want to copy a file if it hasn't finished being written. I thought of using fuser, but it doesn't seem to be very reliable. I vi'd a file in one window and then ran fuser against the file name and got nothing back. I'm just writing a simple bourne script on RHEL.

You can try to start the mysqld daemon with:
shell> /home/mosty/mysql/bin/mysqld --skip-grant &
and use the command line tool /home/mosty/mysql/bin/mysql to connect to the mysql database and look at the grant tables:
shell> /home/mosty/mysql/bin/mysql -u root mysql
mysql> show tables
I wrote a test program to get the CPU utilisation. I hope to extend it to take cpu utilisation on multi core machines. Hear I used the equation for taking cpu utilisation given at [url] of JmSchanck post. But when I match the output of my program against 'top' and 'system monitor' output it seems quite high. Sometimes cpu utilisation goes more than 100%.
So the given equation in that url is correct? can anyone give me the equation to take CPU utilisation?

I am trying to use a shell script to find a string in a file and do something when found. code...
What should happen is pppd will start in a different process and stream it's output to pppdout. pppdout should be created in the current folder. Then the script should periodically check the pppdout file for the string Script (which eventually will appear, some seconds later) and when found exit the script. Ultimately the script will do something useful when the text is found. However, the output from the program is a repeating: 'scriptname.sh: 12: FOUND: not found'
Where scriptname.sh would be the name of your script and 12 refers to the line with 'done'.
Why does grep not find the text, or at least why deos my script not check the grep output correctly?
I wanted to make some modifications to a Kate plugin, so I cloned the git repository, started doing a few changes, and it compiled. The problem is that when I run it, it uses the version of the plugin installed in the system, not the one compiled with Kate.

View 2 Replies View RelatedI started to run a C++ my program in Linux and I don't know how to test my program that works fine with a text file. This is a project for my uni and to explain more clear, My program is a sample database for modify or add and search and it read data from a binary file and also write into a binary file. I have got an input from my lecture and she said after compiling in Linux I must write:
1-to compile:
Code:
g++ (files with cpp)
2-to see the output:
Code:
./a.out
3-to test with input:
Code:
./a.out < input.txt >
My problem is in step three. What I must write in the command part after" step2" to see the output?
I ran a perl script in background with nohup and disown to make sure my script runs even after the parent process is terminated.
Method 1: nohup
> nohup perl run.pl &
[1] 2080
Method 2: disown
> perl run.pl &
[2] 2448
> disown
In either method, the script process doesn't seem to connect to init process, when I checked using pstree command. I thought, the disown or nohup command detaches the process from its parent and attaches it to grand grand parent init process. And it disables SIGHUP signal to my script process. But the pstree command didn't show me what I expected. It still shows my script process attached to my current terminal process. I just don't understand the concept behind these two commands (nohup and disown). Is there any way, I can see the list of processes that are run by nohup or disown command?
In my perl script I'd like to test if a string is written in uppercase letters or not. How can I do that? This type of test don't seem to work, so there must be other ways of doing this:
Code:
...return true.
I can create a subroutine that compares each character aginst a list of uppercase letters, but I'm hoping there's allready a build in routine in perl that does this...
I'm trying to do the following. from a php webpage click on a link, that opens a shell/cmd and runs an open ping to the device. so it must actually open a shell (for linux) or cmd (for windows) and run a ping to the specified ip. Currently i'm running an exec command, but for this i need to wait for the result to be fetched and print it out. I want to monitor it in realtime, by just clickingon the button. How to get this working?

I am exploring the Python 3 standard library and am currently attempting to test the bin function. It converts an integer into a binary string. I believe the module I wrote is flawed somehow. Here's the source code:
Code:
#!/usr/bin/python3.1
#This module tests the bin() function.
import sys
def get_input():
x = input("Enter an integer: ")
def use_bin():
[code]....
As you can see, the binary form given is always 0b10111. I'm no expert on binary code (or hexadecimal notation), but surely 9000 and two would have different results?
EDIT: Added a line in the module to repeat back what integer the user entered, and then the binary form. It would appear that no matter what integer the user enters, Python thinks it's "23".
Example output:
Code:
>>>
Enter an integer: 1
You entered 23
The binary form of this integer is 0b10111
>>>
I'm writing a code to get the index of the last occurrence of a given substring in a string.
Code:
int StringHandler::lastIndexOf(string src, const string s) {
unsigned int lastIndex = string::npos;
if (src.find(s, 0) == string::npos) {
return -1; } else {
bool isLast = false; unsigned int i = 0; do {
lastIndex = src.find(s, i);
if (lastIndex != string::npos) { i = lastIndex + 1;
if (i == src.size()) { isLast = true;
} } else { isLast = true;
} } while (!isLast);
} return lastIndex;
}
My problem is: execution steps into an if with a false condition! Check the values of i and src.size() at the right panel. How could be possible for the program to run the highlighted statement? The if condition above is false! [URL]. I could use char arrays, for example, but this kind of false validation has happened to me more than once, I'm using G++ 4.5 with these flags: -O0 -g -Wall -c
I am fairly new to bash scripting, and I am trying to test a variable against a number range (1-3). This is what I have used so far: The user enters a value, then
while [ "$PROV" != "1" ] && [ "$PROV" != "2" ] && [ "$PROV" != "3" ] && [ $COUNTER -lt 4 ] || [ -z "$PROV" ] && [ $COUNTER -lt 4 ]; do
clear
echo

Is there a cleaner way to do this? Something like:
while [ "$PROV" != "1-3" ]&& [ $COUNTER -lt 4 ] || [ -z "$PROV" ] && [ $COUNTER -lt 4 ]; do

I want to test my system call that be goint to add to kernel, But when i finish compiling kernel, i found my system call code not work. the code i want to return the system time "struct timespec":

Few months back I learnt a *few* concepts about bits/bytes and started writing a program for bit packing in C++. Now that program has grown upto 600 lines and I am still working on it. Yesterday I realized I missed some special cases due to which the program was malfunctioning. Now I have modified the program and it is working properly but I think If I would have designed all the possible test cases before writing the code, I would have finished the program long ago.
I. What is proper way to design the test cases before coding?
II. How should I make sure that I do not miss any cases while making the test case doc. ?
III. Does writing test cases prior to coding solve messy code issues or should I consider something else ?
I was windering, if you are writing a C program, I don't think you are supposed to commit the .o files and executables. How can you test your program without making a copy outside the git working dir?

I'm in the process of setting up a script in perl to make 1,000's of curl calls to my companies application on our test server. Our software does all sorts of tracking of data based on IP addresses using geoIP, so i was wondering if anyone knew of a way to fake these addresses to the server?I know a big issue with the IP faking is the return path but i dont really need this. I also cant do it on the hardware level since the script is going to be picking lots of different IP's at random.Anyone have any idea if this is possible and if so, are there any known libraries i can use for this? I prefer perl but any Linux compatiblie scripting language is fine.
View 1 Replies View RelatedI am writing a script to do a speed measurement from my ISP's test ftp server. To do this interactively I connect to the server, enter credentials, enable hash and download a test file. The process concludes with something like
Quote:
################################################################

1048576 bytes received in 2.87 secs (356.6 kB/s)
So I entered the credentials for the server in my .netrc file and created a little bash script as follows

#!/bin/bash
cd ~/Desktop
# poiuytrewq is the limit string of the "here" document

The script executes as expected EXCEPT that I do not see the statistics at the end of the transfer. It terminates thusly

Way to test permissions on all files/folders into a folder recursive, then if those are not user:user then do :
Code:
chown user:user thatconcernedfile
The problem with that
Code:
chown user:user -R /folder
is that it is doing changes on file permissions whihch are already ok. If you wanna maintain a specific permission on a folder this is really not good this :
Code:
while [ 1 ] ; do
chown user:user -R /folder
# /folder contains 6.0 Tb
sleep 2s
done
