Programming :: Passing Command-line Arguments To Qglviewer Application?

Jul 13, 2009

how to use QGLviewer. I want to give my program a file name as a command line argument. All of the sample programs I find have a main.cpp file like this:

Quote:

#include <QApplication>
#include "window.h"
int main(int argc, char *argv[])

[code]....

Then the Window class, which is derived from QGLViewer, does all the program's actual work. If I want access to argc and argv, for example, to open and read a file that's passed as an argument, what would handle that? Is there a built-in way to get the arg variables to the window class, or do I need to just write a loadfile function and pass them?

Programming :: Syntax For Passing Arguments In Csh Aliases?

Mar 22, 2009

I want to write a little time-saving alias for my .cshrc file that will move files and then cd to the directory I've moved them to. What I can't quite figure out is the syntax to say 'move all the arguments except the last one.' Here is what I have:

alias follow 'mv !:1-$-1 !:$; cd !:$'

This actually seems to work, but it also gives me an irritating error:

mv: cannot stat `destinationdirectory/-1': No such file or directory

Similarly, I tried:

alias follow 'mv !:*$#argv-1 !:$; cd !:$'

Again the move and cd are successful, but again there is an error:

mv: cannot stat `destinationdirectory/0-1': No such file or directory

Programming :: Passing Arguments To A Bash Source File?

Apr 24, 2010

Is it possible to pass arguments to a source file in a bash script? For example

How would you check for the passed arguments in funclib without getting confused with any arguments passed to the main script?

Programming :: C Syntax - Passing In Unknown Number Of Arguments?

May 18, 2009

I need to write a wrapper function around the mvprintw function, like so:

int smvprintw( ? )
{
// Do various checks/modifications on the first two arguments (int y,
int x) first,
// and then
return mvprintw ( ? );
}

How should I write the args for smvprintw so that I can pass all the data correctly to mvprintw, and also do my checks on the first two args (for example, to modify them)? I'm confused by the prototype of mvprintw: This is mvprintw as listed in the man pages:

int mvprintw(int y, int x, const char *fmt, ...);

And this is how I saw it in ncurses.h:

extern NCURSES_EXPORT(int) mvprintw (int,int, const char *,...)

I believe the "..." refers to the unknown number of items after const char * fmt. Will it suffice to do something like "int smvprintw(int y, int x, const char * fmt, void * etc)" and then "mvprintw(y, x, fmt, etc)" inside the function?

Programming :: Case Statement Passing Multiple Arguments?

Aug 7, 2010

I've started dabbling with the case statement in order to pass some option's arguments into variables. I do not think I am doing this right.

Code:

usage() {
echo "Usage: $0 [-z|--snooze] [-c|--channel] [-p|--playlist]
[-m|--message] [-v|--mpcvolume]"

[code]....

As you can see, I want to pass arguments depending on the option(s) chosen by the user; ie. --snooze, or --channel. By default, if no options are chosen, I'll display a usage message; though in the future I'll provide some sane defaults. I'd like to create a case statement to handle passing arguments to any number of options; something like:

Code:

wakethehellup.sh --snooze 20 --message 'wake up!'

and for the other arguments, it would have a default set. The case statement I provided fails with a syntax error "syntax error near unexpected token `$2'" near the '--snooze' in the statement, so I take it you can't pass a parameter in this way; but I'm confused as to how I'm supposed to pass different parameters to different options without the options being confused as parameters.

Programming :: Get "Unmodified" Command-Line Arguments?

Sep 10, 2010

Is there a way to retrieve the arguments in one big string, rather than split into a "char*[]" in C/C++?

It would be nice to get this: "appname --option=value argument argument", rather than "appname", "--option=value", "argument", "argument", etc...

Simply concocting the strings together will not do, since I would like to get the arguments before any OS interaction (i.e.,

Code:
appname --option="hello"
translates into
Code:
appname --option=hello
(quotes are lost). Here is the output of just such a problem:

CentOS 5 :: Parport_pc Command Line Arguments Ignored During Bootup?

May 9, 2011

I am having trouble trying to get the kernel to accept some command line arguments for parport_pc during bootup. I have a custom base board with a PC-104 CPU board connected to it through the ISA bus. On the base board I have 3 parallel ports mapped to addresses, 0x150, 0x158, and 0x160. Only the first one needs interrupts, the second two do not. So, on bootup I load the parport_pc module like this modprobe parport_pc io=0x150,0x158,0x160 irq=3,none,none I have been running an older RedHat kernel, 2.6.11 for the past few years and this has been working flawlessly. I had the above modprobe call in /etc/rc.d/rc.local.

Now I am trying to set the system up to use CentOS 5.5, kernel 2.6.18-194.el5. What happens is, the module inserts OK, but the system never recognizes the ports. (i.e, they do not show up in /proc/ioports)
But, if I log into the system, then rmmod parport_pc, then re-modprobe it as above, it works just fine and now my ports are visible. This is an embedded system, expected to just come up and run, so kicking it into action by hand is not an option.

I have tried putting a parport_pc.modules file in /etc/sysconfig/modules so that it will be seen by rc.sysinit, (some site I found while googling said modprobes need to be done earlier than in rc.local),and again, the module gets inserted but the ports are not seen. I have also tried putting rediculously long pauses between each step of the modprobing of the parport stuff;

Server :: Passing On Command Line Switches To Other Programs?

Nov 10, 2010

On our server we have a certain directory, say /storage, that contains many large files. They are all compressed (gzip). Many of our users are not computer-savvy, and so when one of these files is needed, they will copy it to their own directory. Consequently, we have multiple terabytes of duplicate data. I'd like to enforce an alias whereby if someone tries to use cp on a file from /storage, they will instead create a symbolic link. My idea was something like:

alias cp='cp.storage'
File cp.storage:#!/bin/sh
truePath=$(readlink -f "$1")

[code]....

The conditional checks whether the file being copied begins with "/storage". The problem with this is that if someone wanted to use cp with any options on a file not in /storage, those options would be obliterated. Can someone guide me as to a good way to accomplish this? Either a way to get the options from cp into cp.storage, or another approach not using alias this way. Everyone will be using bash.

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.)

Ubuntu :: Incrontab Not Passing Arguments To Bash Script

Feb 28, 2010

It seems incrontab wont see spaces properly at all. I setup a script to echo the arguments passed to it by incrontab to a file, and no matter what I put around the arguments on the incrontab file it will count a space as the next argument.

I have written a script to automatically retrieve imdb artwork for a given filename. Here is the script:

Code:

You can ignore all the commented "echo" commands that was just me testing. Anyway, the script work fine, however I am trying to use incrontab to monitor a folder, when a new (video) file is moved into the folder, it should execute the script and retrieve the artwork. My problem is, when incrontab passes the $# argument to my script, the script wont work because the spaces aren't escaped.

Here is some more detail:

Incrontab

Code:

Code:

The problem is, the script GetArtwork, doesn't see "Bangcock Dangerous" it just sees "Bangcock"

I have tried putting quotes around the $# in the incrontab - this just makes the script see "Bangcock (notice the single quote character)

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.
