And sprintf() to save the number back to a string.

K&R is very good book, but in my opinion you should have some knowledge about the language first. Also here are some resources i found useful: Cprogramming.com: How to Get Started with C++...

One more thing - you call return system() in for(). return will terminate main() immediately so you won't have your script executed argc times. I'd suggest to save the return value of system in new...

Hello,
I am debugging a program which works as daemon. It sigfaults, unfortunately I'm unable to generate core dump file. Here is what I am doing:

tsurko@bastila:~$ ulimit -c unlimited...

Not exactly. As it was already mentioned when you compile the program it is "converted" to machine instructions. From this point you can' restore the original source code - it's just not possible....

You can also include rownum in the select. For example:
SELECT rownum, filed1, field2 FROM table WHERE field3='X';
ROWNUM is the number of the row - it is added by Oracle to every query.

Thank you for your reply. For my needs I think that the flowcharts and eventually doxygen will be sufficient.
I've read about the flowcharts in wikipedia (http://en.wikipedia.org/wiki/Flowchart)....

Hello,
I'm wondering what methods and tools are used to describe procedural programs? Is UML suitable for such tasks? I've studied SDL in the university - we used it for specification of...

Doesn't work on my Ubuntu machine. You can try something like this in bash:

#!/bin/sh

for i in `seq 1 20000`;
do
istEnabled=1
done

lagigliaivan, this works, but it won't compile on windows I think. Actually I've solved my problem with windows specific functions :(
Many thanks to everyone about the replies!

Please tell us in what language you are writing. This way it's much harder to help you.
But no matter what's the language I think the problem is with the double (()).

I have something on my mind, but if this is for training purposes there is no profit for you just to solve your problem. Try to workout something alone, post it here and I'm sure that a lot of good...

Hello,
I need to implement a locking system in C. My problem is how to make the check if the lock file exist and locking it atomic operation.
I want to make something like this:

FILE*...

Or just escape the space:

mv ABC\ XYZ.TXT ABCXYZ.TXT

I also think this is not possible. Here is a test on my linux machine:

root@bastila:~/work# cat hello.sh
#!/bin/sh

echo Hello
root@bastila:~/work# chmod 701 hello.sh
root@bastila:~/work# ls...

Could you show us how you use this code in your script? If you want to save it in a variable try something like this:

COUNT=`echo $WORD | grep -oE [[:digit:]] | wc -l`

Something like that - you can create a virtual machine (virtual computer) and install on it whatever OS you want (and is supported) just as you have real PC. VirtualBox is just one solution.

First of all thank you very much for your answers.
I do apologize for this thread - my mistake. I used another keywords and didn't find what I wanted. This won't happen again.
I know that maybe in...

Hello,
I want to start learning Perl, but I need some expert's advice:) Could you recommend me any online manual or book to start with? I have some experience with bash and C, so I am not a complete...

Yes, you are right. Your variant is better! I'll edit my post.

Hello,
I had to make an ssh connection to remote server from a bash shell script. I've summarized my research and I want to share it with you. I hope it will be useful to somebody or it will get...

Actually my point was to call script_b from script_a. And the code up there was meant for script_a. But of course there is no problem to create new script to call both of them.

You may try something like this:

#!/bin/sh

# Your code here

#Here you start the script
ssh $SERVER_NAME script_b.sh

#This should also do the job:
ssh $SERVER_NAME <<EOF
script_b.sh

I'm not familiar with HP-UX, but can't you use some packet filtering software to achieve this?

In bash '\' (backslash) is used for escaping special characters (for example spaces in file names). However I don't know why it's necessary to escape '/' in this case.
