i was wondering if someone could help me figure out a script for global variables i'm trying to set for a group of command line arguments:
basically i'm trying to set: if $# = 3 then i want to search for each all string $1 $2 $3
if $# = 4
then i want to search for each all string $1 $2 $3 $4
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.
View 1 Replies View Relatedhow 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?
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:

how to pass an array as a command line argument in a shell script?
View 5 Replies View RelatedI 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;

View 1 Replies View RelatedI'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.)

Is it possible to allow a group/user to execute a command, where one of the parameters of the command is a group as well? example that does not work as intended:

Is there a method at the command line to copy files from one location to another and retain the source files group and user?I'm migrating some MySQL files from one machine to another.I want to back-up the original files in the directory presently. They have owner:group of mysql, some have owner:group root:mysql and so on. To copy them under cli or Nautilus everything changes to root for I execute sudo cp or gksudo nautilus and copy via gui.
Since it is MySQL data I could simply do a dump of the database and restore it on the other machine. But there's about 20 db's and I want to do this via a copy for it will be faster - at least that is what I think.
Code: cmd='date | wc'
$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?
I am trying to learn how to pass more than a one-command startup for gnome-terminal.
I will give an example of what I'm trying to do here:
Code:
#! /bin/bash
#
#TODO write this for gnome and xterm
USAGE="
${0##*/} [-x] [-g]
code....
However, running with the -g option to invoke gnome-terminal, I get a "There was an error creating the child process for this terminal" error.
This same error occurs if the gnome-terminal line is changed to
Code:
gnome-terminal -e mcTerm
Is there any way to pass more than one command on to gnome-terminal? I have tried various single and double quoting senarios and in a final attempt, I abstracted to an exported function all to no avail. Perhaps even though gnome-term is better at many things than xterm, xterm trumps it in this instance.
