it takes the output of an sql query.
if i have to check for no rows selected,how could i do it?
i want to do like this:
if(no rows selected)
{
do this;
}
i can thought that it will open a shell, execute the parameter (shell command) and return the result in a scalar.
But, execute 'system' function in a perl script is faster than a shell command.
It will call this command in C?
If yes, what's the difference between
rmdir foo
and
system('rmdir foo');
Thanks,

-runs a CLI script
-reads the resulting .out file and converts the data in the file to an HTML table.
Here is some sample data from the .out file:

10.255.202.21 2161941840 1484352
10.255.200.0 1642646268 1163742
10.255.200.96 1489876452 1023546
10.255.200.26 1289738466 927513

Any help would be much appreciated.

If I have a hash in Perl that contains complete and sequential integer mappings (ie, all keys from from 0 to n are mapped to something), is there a means of converting this to an Array?
I know I could iterate over the key/value pairs and place them into a new array, but something tells me there should be a built-in means of doing this.
What is the best way to achieve sscanf like functionality in perl?

How do I do the following in Perl in order:
a) curl a page and save it to a variable

I am new to any scripting language. But, still I worked on scripting a bit like tailoring other scripts to work for my purpose. For me, what is the best online resource to learn Perl?
Is it possible to use a Perl hash in a manner that has O(log(n)) lookup and insertion?
By default, I assume the lookup is O(n) since it's represented by an unsorted list.
I know I could create a data structure to satisfy this (ie, a tree, etc) however, it would be nicer if it was built in and could be used as a normal hash (ie, with %)
So I am trying to read an XML file into a string in Perl and send it as part of a SOAP message. I know this is not ideal as there are methods for SOAP sending files, however, I am limited to having to use the SOAP that is set up, and it is not set up for sending with file support.
Therefore I need to parse out the markup tags < and replace them with []. What is the best way to do this?
I don't really understand how scoping works in perl modules. This doesn't print anything. I would like it if running a.pl printed 1

a.pl
use b;
print $f

Please don't suggest greping /etc/passwd :)
In ksh, I'd use
cd /usr/src/sys
How should I write it in Perl? A conversion such as
cd /usr/src/sys ---> chdir '/usr/src/sys'
Maybe the following would be better:
execute "chdir '/usr/src/sys' "
