How do you Compile programs using cc?? I'm lost. Do I need to buy C or what? I'm only going to use it very few times a year. From what everyone seems to be telling me, it sounds like it is build into the Unix system but I'm having no luck. Please help or just point me in the right direction.

I notice that (Mandrake) Linux and Windows do not seem to operate alike in terms of installing third party software.
Windows, on one hand, creates icons and adds items to the Start Menu, with the help of the InstallShield--or equivalent, of course, but Linux, on the other hand, seems to care... (3 Replies)

I've been trying to create a script to launch several applications at once. I've been researching books and forums, but I end up with more questions than answers. As much as I hate to say it, I don't know if I can figure it out on my own...... (3 Replies)
General Question: If a script calls multiple external programs (external to the script, but still on unix), where do the return codes go?

Hi,
I am running a shell script that executes a program. Inside this program, variables are also referenced using a dollar symbol, eg. $a, $thething, and the shell script is misinterpreting them as variables relevant to the shell script rather than relevant to the program run from inside the...

I am suppose to make a program that cuts the extension off of a file. It uses that .ext to decide which program needs to be used to open the file. This only finds the name of the program from a list of programs I made. My problem is when it has the name of the program it needs to use, how can I... (2 Replies)
Is there a way I can specify the name of a list as an argument to a shell script and then use the values of that list name in the script?
I need to do this WITHOUT using case statements.
Something like this:
check.sh list1
#!/bin/bash
list1="www.amazon.com www.google.com"... (9 Replies)
Hey guys,
Suppose i run passwd via bash shell. It is a suid program, which temporarily runs as root(owner) and modifies the user entries.
However, when i write a C file and give 4755 permission and root ownership to the 'a.out' file , it doesn't run as root in bash shell. I verified this by... (2 Replies)
