I found a solution to my own problem now. =P

This works:


#!/bin/perl
use Shell;
$command = echo("parameters", "go", "here");
print $command; #performs echo

Is it possible to have a perl script and a bash script in one file? Like:


#!/bin/perl
print "This is perl";
#exit perl

#!/bin/bash
echo "This is bash"
exit 0

I added an escape \ to $s1 like you did to $s2 and it worked great, thanks!

I have a very specific problem.

Does s/// work with strings that are contained in single quotes? I've been debugging and I'm trying to replace a string that contains a $ in it. If I use double...

I'm trying to create a general buffer that I can use in my program. It will work with ints as well as strings. So far I've been using a strstream, and it works without a hitch, but I was wondering if...

I am working with form processing and text manipulation, and I found two useful functions; tr/// and s/// They do pretty much the same thing, but I was wondering if anyone could explain to me what...

I found out the problem. It waits because it wants another program to handle the other end of the pipe.

I fixed my codes up and I wrote a script like this to fix the problem:

Hi,
I'm trying to write a program using named pipes, and I'm having trouble opening it. In another program I call this line:

mkfifo("./fife", 0777);


So my named pipe exists and I see it...

If you want to connect to your own network by going outside and coming back in you need to know your external IP address, and you need to tell your router to forward your port(1234) to your server...

Thank you, I found out our mainframe does have it already.

Does anyone know where I can find the pthread library for Linux? And I don't want any rude "go google it" responds. I tried that, and all I came up with was one download available for win32.

depends what operating system you have. on linux type

in windows...i dont think it differentiates files that are executable and text files except by the extension, which...

This code snippet actually contains a few nifty things. There are two functions, hasVisited() and main(). hasVisited() makes use of a very handy function for CGI programmers: getenv. You can see I...

I'm trying to get into some practice with Mesa GL and I know it works for the X desktop. Will it work the same with Gnome or KDE? Are those based off of X?

Thanks for the clarification. I noticed that his was default initialized to 0 so i thought maybe it depended on the compiler. Now I know it only does that with global variables.

Hey,
In your printshippos function, you declare checkFlag at the top of that cpp file. When you initialize it like that w/o any number, it is either an unknown number, or in most cases, 0. The...

hey, would you mind posting your code of sending me your code? I'd like to see your working code just so I can study it.

I noticed too that you declare shippos inside an if block { } and try to refer to it in the next if statement, which is in a different block of code. That is probably why it prints out as 0+228...

Here is a link that might help you.

I think the problem is because when you declare a variable static it affects the lifetime of it. You declare it inside the If brackets { }, so it will be destroyed at the end of the if statement....

I compiled your latter source code, and it worked fine. I could input the four numbers and it would give me output. You say it quits before it outputs the text? If you are using Visual Studio, if you...

You use list = names which assigns names to list in your code. You may mean to have that switched. Also, why not read directly into names? I am pretty sure your dispute between 1 and 2 dimensional...

Acquire,

The first thing I noticed was this char names[99][28]= {" "};. If you get an error with that line, try using single quotes instead of double quotes. Double quotes are associated with...

I like this snippet. I always find this kind of C++ code very useful.

Alright, I read the page a few times, and tested a few things and still I was frustrated. I decided to do away with the templates, because in my case I am only going to use it for int. I simplified...
