1. What file do i have to edit in order to include /usr/local/bin in the class path (ie. I put an executable in /usr/local/bin and when I try to execute it, it says the command cannot be found, etc.) EDIT: Solved, just didn't set PATH correctly. EDIT: New problem. When I try to execute a program in /usr/local/bin, it says "fopen: john.ini: File not found" Yet when i cd to /usr/local/bin, it doesn't say that. What would cause this?
2. Once I get my system setup the way i like it, how would i go about making it into a bootable CD/DVD?
3. How would I pass arguments from a shell script to a program?
I am using getopts to take parse optional arguments but i also pass in mandatory arguments first

arg1="$1"
arg2="$2"
shift 2

I need to pass a large number of arguments to a function which takes variable number of arguments, such as gtk_list_store_new. But it doesn't look nice if i write something like gtk_list_store_new(NUM,TYPE_A,TYPE_B,TYPE_C,...,TYPE_OMEGA); because of large number of arguments. And, it will be a trouble to change number of columns because of need to manually change arguments to large number of such functions. So, how can i pass all the arguments to a function using a loop? Something like
Code:
for(i=0;i<NUM;i++)
{
push_arg(args[i]);
}
call_function(func);
?
Of course, i could just use asm code for this, but is there a portable way of doing so?
P.S. i mean C language.
I wrote a C++ program that uses two different parsers. The first parser is reading program arguments from command line:./mybin arg1 arg2 ...then during program execution there's an interactive prompt asking for more parameters:
...
>> (second bunch of arguments here)
...
I'd like to run my program inside a bash script, but I don't know how to give the second level arguments.
Running a program with arguments using a shell script
View 1 Replies View Related(For function arguments): Scalar arguments are passed by value, which means that a copy of the argument is made for processing in the function, and changes to the argument in the function won't be reflected back to the calling program. Objects though, are passed by reference: any changes to them in the function are reflected in the calling program. What sense does this make? Why have they done this?
View 3 Replies View RelatedI've got a sticky little problem with a bash script. Please consider the following code:
Code:
#! /bin/bash
processArgs() {
echo "Count = $#"
while [[ $# -ne 0 ]]; do
echo $1
shift
done
}
processArgs $* If I call this script with Code: ./script first second third it'll print each of the argument on a new line - exactly what I would expect. However if I call it with
Code: ./script "Single Argument" "Second-Argument" it splits the first argument in two using the space as a delimitor. The problem appears to be the call to processArgs, where $* doesn't honour the quotes around the variables sent to the script.
I am calling script 2 from script 1. Is it possible for me to pass the output from script 2 to script 1 as the value of a variable. for eg.. path=`/XXX/XXX/script2.sh`

I'm playing around with a bash script to pass files to a program (such as VLC). I thought something like this would work:
vlc $( ls | sed 's/ /\ /g' | tr '
' ' ' )
ls shows the files in the current directory, then sed changes spaces to " " (to escape them) and finally tr removes the line breaks. I end up changing:
01 - Music Track.mp3
02 - Another Track.mp3
to
01 - Music Track.mp3 02 - Another Track.mp3
"vlc 01 - Music Track.mp3 02 - Another Track.mp3" works if I type it manually but my script reports a problem with `-'
It seems it's not escaping the spaces.
I'm trying to do a shell script which are suppose to run a program as a specific user at system boot up. The problem is that I don't know for sure how to make the script add the users password to the prompt when it's necessary.
Basically the program would be run like this:
sudo -u extrema program_name -r /srv/program_name -d
and in this example the password is, "hidden".
How would I make this script run this program as user extrema with the password "hidden" at boot-up? I know how to put the script in the rc.X directory and so on, its more the syntax of the code.
I've written myself a linux program "program" that does something with a regular expression. I want to call the program in the bash shell and pass that regular expression as a command line argument to the program(there are also other command line arguments). A typical regular expression looks like "[abc]_[x|y]".Unfortunately the characters [, ], and | are special characters in bash. Thus, calling "program [abc]_[x|y] anotheragument" doesn't work. Is there a way to pass the expression by using some sort of escape characters or quotation marks etc.?
(Calling program "[abc]_[x|y] anotheragument" isn't working either, because it interprets the two arguments as one.)

I wrote a C program using Pthreads to compute the product of 2 matrices. Each element in the product matrix is computed in a separate thread. Eg: Thread (i,j) computes the element C[i][j] of the matrix C, where C=A*B. A is m*n, B is n*p, C is m*p. m,n,p are given as command-line arguments. A and B are initialized to random values from 1 to 10, while all elements of C are initialized to -1.But some threads do not get their arguments (i,j) correctly. So some elements C[i][j] still remain as -1, even after the program is over. My OS is Ubuntu 10.10 (Maverick Meerkat) 32-bit.I ran the program on another computer and it worked correctly. Is it due to a problem in the Pthreads library in my OS? Please help me. I have attached the source code.

I have a weird/stupid question. How do you know what command would start an application after installing it, if the synaptic package name doesn't match?
For example google chrome and lmsensors. The first appears as Chrome in Synaptic and the second as lmsensors, but to run them you have to type google-chrome for the first and sensors for the second in the console to start them.
When I did locate sensors or locate chrome/chromium, nothing came up in the search that would hint me that I need to run those commands. I had to rely on a google search and look for someone else's answer. Is there a better way, one that I can figure it out on my own?

I'm trying to compile the hidtouch driver, but hit a snag. The error I get is
[code]....
Context: this is the driver for the touchscreen attached to an LTSP client. The server uses the AMD64 arch, the client uses the 1386 arch, both Debian. The client does start, but lacking a pointer device the pointer is useless. The build takes place on the server, in the i386 chroot of the LTSP setup. Basically, I'm stuck now...
I need to call functions that match an input string (if input str = "func1", call func1), so I have this:

"); }
[Code].....
In the above example, the functions take no input arguments. Can they take a different number of arguments, for example, function_a(int), function_c(int, int), function_e(int, char, int)? How can I do that?
I want to know how to get eg. the contents of a form on a webpage which has been passed to a server side PHP script, inside for example an array which I can read. I've been reading a ebook on PHP which as far as I can see doesn't cover this inside it.
