i'm writting a program, that creates semaphores and shared memory. It asks from the user to give anything to write in the shared memory. Now, i want this program to do this,not only once, but repeat, and stop as soon as the user gives the word "quit". i added a while loop, but i don't know how to stop the program.

I have data that looks similar to this -
Quote:
John Smith (Address)
123 Main St
Unit 1
[code].....
So I need everything between each name, but I am not guaranteed that each time I match a name that I will have the same amount of lines, so I do a range pattern search line this to get all lines, no matter if there is 5 or 10 or 15. I simply do a loop that goes through the whole array until I hit the match, and this is my search pattern.
Code:
if ($LINE =~ /^s+$SELECTED_NAME/ ... $LINE =~ /(Address)/) {
push @ADDRESS_INFO, $LINE;
}
This works perfectly... until I hit the end and it doesn't get its final pattern match because it's at the end and there is no next entry with a (Address) line. So as a 'hack', I ended up inserting a final scalar at the end of the array that just says (Address) so it knows it's at the end. Ideally though, I'd like to do an "or" statement that says search for Address || return true if I hit the end of the array. How would I match on "End Of Array" essentially?
I have a Python program looks like this one :
Code: import os

How do I get this loop to stop on each increment? This script does work but I would like it to stop at each increment, remember what the value of $n is, then continue until it gets to 7. I have worked so hard on this. My brain is hurting now.

View 2 Replies View RelatedI am trying to setup LDAP server on Ubuntu 10.04 and am sticking to the old /etc/ldap/slapd.conf file configuration.
I had to comment ldapi:/// from /etc/default/slapd since it was giving 'Address already in use error'. Also had to juggle with pid directory and file issues
After that I was able to start the slapd daemon (service slapd start) but now I am running into multiple issues:
1. Can't stop the service with service slapd stop
Code:
## Service stop returns 0, maybe because start-stop-daemon is not giving error
#service slapd stop
Stopping OpenLDAP: slapd.
# echo $?
0
Will switching to BDB database resolve this ?Also can't I slapcat at non-root user ??
I am trying to give access to ONE single user to start and shutdown tomcat server. The problem being, when I enter syntax: username ALL= /etc/init.d/tomcat5, /usr/local/tomcat/webapps, PASSWD:ALL This gives the user access to start and stop tomcat but also gives user access to start and stop other services within /etc/init.d - such as httpd etc... What is the proper way to give user access to start and stop service, and limiting that power to only one service....
View 2 Replies View RelatedIn Ubuntu 10.04, we're supposed to use the following command to stop the X server (assuming the usual Gnome desktop environment): Code: sudo service gdm stop.The problem is, this has never worked correctly for me. I see a bunch of messages about things being shutdown, then it hangs. I've waited up to several minutes for something to finally happen so I can log in to the command line, but nothing ever happens.What I've always ended up doing is pressing Ctrl+Alt+F4 to switch to a different console. I was then able to log in there and do stuff that required the X server to be shut down, such as installing Nvidia drivers.
Is that how it's supposed to work? It doesn't seem right.Can't post the error message where the command hangs, because obviously I have to be running the GUI to post here. But I'll jot it down next time I try the command.
I am interested in learning 3D programming. The thing is, I would hate to put too much effort to learn something that doesn't have future and is dying. My favorite language at the time is Java. My goal is professional programming.
So I have several questions:
1. Should I learn JOGL or start learning C++ and do C++ openGL programming?
2. Is there a big difference between JOGL and C++ openGL programming?
3. Is it worth to learn openGL? Does it have a future?
4. Is it a big difference between openGL and directX coding?
5. If choosing Java, then JOGL or LWJGL?
Why and what is the main difference between them?
Recordmydesktop sounds great. I installed it in F14 with both the gtk and the qt gui. Both of them start the recorder, but I can't find any way to stop it.
I really thought something like this would have some reasonable controls, like a time I could set for it to stop, on some way to stop it manually, but the only way I can find to stop it is to kill the process. If this were true then it would be junk, so surely there is some way to control it.
I just installed Opensuse 11.4 in my desktop:
HP Pavilion P6210es
IPMEL_AE (Evans)
Chipset Intel G41 Express
Intel Core 2 Quad Q8300
RAM 4GB
[Code]...
It is in a HD, and I have 2 HD more one with Win7 and the last with Ubuntu 10.10. When I run OpenSUSE 11.4 a fan does not stop, it is always turning. It is is very annoying. It does not happen with the others OS.
This is an examination senario. We have mulitple users logging into a RHEL-4 server using putty. These people are part of a same group. They are giving UNIX shell script exam.They are helping each other copy the code by using redirection to /dev/pts/x. Is there any way I can stop this redirection?
