Programming :: URL With Parameters Containg Ampersand?
May 20, 2010
[URL]... The above url is generated by PHP code.
Code:
if($msg=="No capex advice")
echo " .. <a href="upload_capexadvice.php";
if($msg=="No purchase order")
echo " .. <a href="upload_purchaseorder.php";
if($msg=="No invoice")
[Code]...
I pass two parameters in a URL, s and q. I recently ran into the problem that the & in the value(aerial&satelitecity)causes a bit of trouble so I need to replace it. After some research I found that it needs to be replaced by %26. I've tried the standard PHP functions htmlspecialchars and htmlentities, but they translate to & Is there another function that I haven't found yet or must I write my own?

Specifically I'm trying to run xmacro from within a c program. If I were to run it from the terminal I would do it along the lines of Code: xmacroplay :0.0 < script_file.txt, but I want to run it from my c program. I'm fine with my c program running it from the terminal if that's possible and easier but I'm guessing there must be a better way.

I have a bash script where I am replacing a date with a variable
Code:
variable="date"
sed -r "s/([0-9][0-9])/([0-9][0-9])/([0-9][0-9][0-9][0-9])/$variable/g" /path/to/file.txt
I have googled but cant find any info on what the -r, or sometimes I have seen -i and -e, after the "sed" I googled "sed parameters"
r appears to output the replaced date, but not change the original file. Usually using -i will change an original file for me. Does anyone know what the -i, -e, -r are about? A link to an explanation would be good, as I have been unable to find one in my searches.

I know a program running in the background can be brought to the foreground by typing 'fg'. So, if
command_line &
really runs the program in the background, my question has just been answered. But then all reduces to this question (yeah, I know; but I'm asking in earnest): does the ampersand sign make the program run in the background?

I get no print to stdout on screen from the C code.Does bash somehow block or mask it?I get print from bash. I get this error in the non-test bash script like: let "rdval = $rdstr"syntax error: operand expected (error token is " ")The let command prints rdval= but I presume this is due to the printf test statements getting in the way.I am getting no compile errors. Why does the C code not print the values specified?

I am setting up my test / development machine with the following scenario in mind : I boot the machine and then select one of a number ( e.g. 3 ) boot options in Grub ( Normally "OpenSuse", "Safe Mode" etc., but in this case "System Restore Dev.", "System Restore Test" ). The only difference between these options are the settings ( e.g. "vga=378" ) in these cases something like "distro=dev" / "distro=test".
In a script run on the booted system I can extract the value of the "distro" parameter ( in this case "test" ) and use it as input for a command line tool. Meaning that name entered as the value for the "distro" parameter is used for loading a file when the system is up and running. The command line tool then restores the partition with the contents of the file and reboots the system.Now, my problem is this : How to I access the Grub arguments? Code snippets ( in shell scripting or python preferbly ) are more than welcome.

I've searched online and found many examples using getopts, but nothing that clearly explains it use, nor any examples of what I'm trying to do. I have a script named "process". It can take from 0 to 3 different options. I'd like to be able to handle these options regardless of the order that they are entered.
Syntax:
process [-v] [-d #] [-h|-?] [string]
-v = verbose mode on
-d # = how deep to do the process, expecting a number parameter
-h or -? = show command usage
string = only process lines containing the specified string
[Code]..

I have two txt files containing x and y coordinates: xcoord.txt & ycoord.txt. I need to open them; read them line by line to get each coordinate; then each time I need to update Xs and Ys parameters inside another file called "dc.in" with the grabbed values.
Finally each time I need to run two exe files ( dc_2002 and st_vac) and produce corresponding output for each Xs and Ys ( dc.in is an input file for this exe files)
I have written the following code but it does not work:

I have tried to learn how 64bit asm (nasm in my case) works and found, among the many disparate pieces of info on the net, a few vague inferences that floating point registers can be used for other purposes than what they are intended for, example: "64-bit Linux allows up to fourteen parameters to be transferred in registers (6 integer and 8 floating point)." This would be fantastic for string operations/manipulation (I have never used asm for floating-point operations), can anyone shed a bit of light?

I have a strange problem with RHEL4.7, with kernel 2.6.9-78.
I cannot set any kernel parameters by editing sysctl.conf file and run sysctl -p, everytime the old value appears, while it was possible before.
I tried to edit files under /proc by using vi when trying to save it gives me: E667: Fsync failed!
While echo 1>/proc/sys/net/ipv4/ip_forward also cannot edit the file.
Also I mounted proc device on another mount point:
# mount -t proc proc /mnt

A couple of weeks ago I installed Karmic. In previous options in Audio CD Extractor I modified a string in the "edit preferences" to set the variable bit rate for MP3 ripping. Specically the option "VBR=4" (Lame New Algorthym) However, I now notice that the "VBR=" option is no longer there!
I've searched around and read some indications that using a newer realease of Lame this is no longer necessary. But its a bit unclear to me. Do I need to insert VBR=4 or not? and if I do anyway will it affect anything?

Just installed squeeze from previous Lenny and am having problems. With Lenny, for the tv card, needed: the modudule saa7134 card=54 tuner=78, i.e. had to give it the card= tuner= stuff - it could not autodetect that bit. Squeeze appears the same:
Code:
[ 5.055340] saa7133[0]: subsystem: 17de:7253, board: UNKNOWN/GENERIC [card=0,autodetected]
So, question, how do I give it the module options? - the problem is 'modconf' will not unload the saa7134 module because it says it is in use, even though the TV is not being used. And # modprobe saa7134 card=54 tuner=78 does not appear to do anything - it does not say anything but nothing shows on dmesg. Here is how tvtime, a fairly fool proof tv player, behaves:
Code:
root@fido:/home/lugo# tvtime
Running tvtime 1.0.2.
Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /root/.tvtime/tvtime.xml
mixer: Can't open device /dev/mixer, mixer volume and mute unavailable.

I installed Debian 6 last night on an older Compaq. For the system to properly reboot and shutdown when requested, both acpi=force and reboot=warm must be in the boot parameters, this was required with other Linux distros installed on this hardware. Otherwise, the system erroneously shuts down when reboot is chosen.
I would like to know how to permanently add these so they pass each time the system is turned on.
I already added these to /etc/default/grub (and ran update-grub afterwards) and at the next startup, noticed they were NOT in the parameters when "e" was pressed at the boot menu.
