Programming :: Parsing Command Line Arguments In PHP?
Feb 1, 2010
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.
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?
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;
I have recently installed MySQL Server on my CentOS box.
CentOS 5 MySQL 5.0.45 (installed using 'yum install mysql-server') I can start the daemon without error by issueing the following command: service mysqld start
The problem is that I want to use a number of the command line options available to mysqld, such as --verbose and When I issue '/etc/init.d/mysqld --verbose --help' I get the following output:
Has anyone used rtmpdump or flvstreamer? They compile well (there is also a package on Packman for rtmpdump, but not for the latest version) and have man pages listing a bunch of command line arguments, but I have not yet figured out how to use them in connection with browser and flash plugin.
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 am able to start up firefox just fine out of my terminal, but i have not been able to find any list of arguments that can be added in the command line. what i'm looking for is that it starts up in Full Screen mode right off. is there an argument that can be added to ti to do that?
I'm having problems with bash quoting. Maybe someone can tell me what's going on.. Basically, I need to create a command line inside a bash script that contains arguments that contain spaces and bash variables that need to be expanded.
Write a script that will take a list of filenames as arguments and output a count of how many of them are regular files, and how many of them are scripts (if the file is executable, it will be assumed to be a script file)
I am calling another executable in my application (C programing) using "system" command which is user interactive program. now i want to pass those args in system command only.
system(" executable ");
Executable will expect 1,2 or 3.
1 is to continue 2 for do changes in settings 3 exit from application
I'm at the bottom of the bash learning curve, looking up, hoping someone can toss me a line. I need to update tracker on my system but this will erase the metatag database I've been building up over the course of months for the purpose of indexing a news archive. So the solution seems to be, 1) save the output of tracker-tag to a text file for all relevant files within a directory, 2) upgrade tracker (since the version in the Ubuntu repositories is very much out of date) and then 3) use a script to parse the text file and pass appropriate arguments back to tracker-tag to rebuild the database. It sounds as though it ought to be simple enough, but I need a push in the right direction, which hopefully will not be off the cliff. Before I confuse my metaphors any further, here's what the text file looks like.
$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.
I tried to upgrade ubuntu , downloaded everything that was needed but I am not able to install anything. It gives an error

I'm building a script for my place of employment. The next step in it is checking what the user input was. Determining if they added a part in there or not. The script prompts for a hostname. Hostnames are localhost.localdomain. Now, I want the script to check to see if they put localdomain and if they did, not to add the domain to the /etc/sysconfig/network, but just what they entered. So say the user inputs:
I need to write a script that will take 1 command line argument. The argument will be a username. The script will determine if the user exists on the system and will print an error if it does not. If the user does exist it will determine if the user is currently logged in, if the user is not logged in it will determine the last time the user logged in and display the file in the users home directory that was most recently modified.
I am using an awk command to print a line from a cvs file.the awk command includes an if statement that filter the output-lets say i want to print all the lines that the price field is greater than 30.i have it working when i put the parameters myself.. but when i try to send them with vars it wont work..i am sending the sign of the if statement - can only be: == , < , >it looks like this:
I am wanting to write a program that runs a program or command-line. Is there are way of making a program that activates a command-line (for example executing 'ps -a -f' or '/home/shared/fah').
In addition to that, I want the program to do a 'ps -a -f' and put the results in a buff, how could I do this.
I'm troubleshooting a batch of scripts I'm modifying, including an IDL script called by a .csh script. the IDL scripts were provided to me by a coworker and my .csh script is intended to automate a lengthy set of extremely tedious and time consuming processing tasks.
I am currently in the process of debugging, and can't get the IDL to print any messages other than critical failures to the screen. Is there any easy way to redirect the stdout to either a logfile or the screen?
I am taking an argument from the command prompt for my shell script ie $1 and i need to use $1 in my awk part of the script.But it actually doesn't get any value when used in awk. accessing this command line argument in awk?
