General :: Pass All Arguments To A Function?

Jul 6, 2010

I'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.

Programming :: Pass Arguments To A Function Using A Loop

Mar 1, 2010

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.

General :: Bash : Pass Command Line Arguments Containing Special Characters?

Jul 14, 2010

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.)

General :: Arch Usability - Pass Arguments From A Shell Script To A Program?

May 7, 2010

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?

Jul 28, 2010

Programming :: Bash Script : Pass Arguments To Second Level Parser?

Jan 14, 2011

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:

I'd like to run my program inside a bash script, but I don't know how to give the second level arguments.

Programming :: Function Pointers With Variable Arguments

Jul 14, 2011

I need to call functions that match an input string (if input str = "func1", call func1), so I have this:

Code:
#include <stdio.h>
#include <string.h>
void function_a(void) { printf("Function A
"); }

[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?

General :: Write Script To Use Function And Still Keep Function Active?

Feb 21, 2010

the function terminates if no key is pressed for 10 consecutive seconds. I tried using the -t option as suggested in some forums, but my version of showkey doesn't have the option of changing the timeout. The options I get are:

-h --helpdisplay this help text
-a --asciidisplay the decimal/octal/hex values of the keys
-s --scancodesdisplay only the raw scan-codes
-k --keycodesdisplay only the interpreted keycodes (default).

Is it possible to write a script to use this function and still keep the function active until an interrupt is recieved?

General :: Passing Commands As Arguments To Functions In Bash Script?

May 31, 2010

I wrote a simple bash script to let me treat any set of programs like a deamon. For example if I configure the script a certain way I can start/stop/get the status of apache, mysql and php all from one command. I am having a bit of a problem though. I am passing commands as strings to a function and then depending on the arguments to the script it might run one of these commands or another. Some of these commands need to beun in the background though, such as deluge-web. When I send "deluge-web &" to the function and it execute it deluge-web does not start in the background. I can't figure out why this is. I have tried escaping the & with ''s and with a , but nothing seems to work. I know that this is some idiotic thing that I am overlooking, but I am a bit stumped. Here is the script configured to start/stop/get status of deluged and deluge-web.

Code:
#!/bin/bash
function checkanddosomething {

General :: Reusing Find Command Results In Mplayer Arguments?

Jan 22, 2010

I wanted to supply mplayer with the output of find command as arguments. The error returned showed spliced names of files whenever spaces occurred. I have subdirectories in my /home/my_user_name/Music/ directory, and in them multiple *.oga music files. The actual command that I issued was

Code:
mplayer $(find /home/my_user_name/Music/ -name "*.oga")

mplayer started but then was looking for broken file names. I am thinking quoting has to do with it to preserve the filename as one string but different attempts were met with inroads:

Code:
mplayer `find /home/my_user_name/Music/ -name "*.oga"`
gave me the same result and
Code:
mplayer `"find /home/my_user_name/Music/ -name *.oga"`

complained about wrong mplayer syntax.
