Programming :: PHP - Ping Test In Shell / CMD Window
Mar 4, 2010
I'm trying to do the following. from a php webpage click on a link, that opens a shell/cmd and runs an open ping to the device. so it must actually open a shell (for linux) or cmd (for windows) and run a ping to the specified ip. Currently i'm running an exec command, but for this i need to wait for the result to be fetched and print it out. I want to monitor it in realtime, by just clickingon the button. How to get this working?

I'm playing a game through wine (fullscreen), when I alt-tab back to my ubuntu desktop, the resolution doesn't change back, but stays at the game resolution.I'm currently using a shellscript that changes the resolution back to my origional resolution (using xrandr -s 0)
Is it possible to check which window has focus using a shellscript.If the game doesn't have focus change resolution to my origional resolution.

Been helping a user who recently upgraded to 11.04 as his networking stopped after the upgrade. One thing I noticed was that he could not get ping to work.Then checked my 11.04 machine and it also fails to ping using Network Tools. I know the network is OK as I am using my Ubuntu machine to write this. Ping from the command line is fine so it is only the Network Tools ping test that appears to be broken.
Asked another Ubuntu 11 user to check his machine and he also cannot get ping to work even though his machine appears to be fine. Again this is only using the GUI tool.I know it is not hardware as I can dual boot and in XP everything is fine and I can ping all my systems. Also I am sharing a folder from my Ubuntu and my Mac shares the folder just fine. The Mac can also ping everything except the Ubuntu box. Command line ping works so it is not a basic network problem.So as far as I can tell the Network Tools ping test is not working. Has anyone else seen this or can confirm that it is broke. How do I report this or get it fixed?

I was looking at this line in an init file:
Code:
test -f /etc/default/postfix && . /etc/default/postfix
Which I understand to mean test that files /etc/default/postfix AND etc/default/postfix exist. Two things

I was trying to write a script, but for some reason I can't test two variables using -gt:
a=`expr $currentSize + 0`
b=`expr $fileSize + 0`
[$a -gt $b]
this is what I get:
[22234534: not found
what is the problem? It seems like I can't check if a variable is greater than another but only if a variable is greater than a fixed number. Is that so? By the way the variables $fileSize and $currentSize exist and $a and $b have a value.

I've searched and read lots about trying to get gnome-shell to run in Virtualbox(v4) with no success on my end. Lots of the posts are outdated and are using Virtualbox 3.
So anyone have any tips or hints for testing the Gnome-shell? (I'd prefer to test in with 10.10 in Virtualbox 4, but am open to upgrading to 11.04 if necessary)

Some may recall I recently gave up on bash, rather than give up my programming style.Surely I will have reason to return but that's another story. My little issue now:I am debugging a new [Korn] shell script. I have a function that performs a specialized match on a string and I see that I am able to call that function with no problem, with both of it parameters. The function does not do any print or echo command - it uses "return" for a TRUE (0) of FALSE (1), as is the shell exit code convention. Thus, I have the following test:
Code:
if [[ match_except_release ${PATH_DIR[$LC]} bin ]]
then

I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.
Code:
if [ $# -eq 0 ] ; then
d=`pwd`
for i in * ; do
if test -d $d/$i ; then
echo "$i:"

Is there some type of functional way to read things in the Python shell interpreter similar to less or more in the bash (and other) command line shells?
Example:
Code:
>>> import subprocess
>>> help(subprocess)
...
[pages of stuff to read]
...
I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.

I'm looking for a feature in Gnome Shell that would allow me to tile all of the open windows on a desktop. Something akin to Fluxbox's ArrangeWindows keyboard shortcut. I know you can tile two windows side by side, but I would need something capable of tiling ALL of them. Does something like this exist, or would I need to look into writing a Gnome Shell extension?

I want to copy files from an incoming directory, but don't want to copy a file if it hasn't finished being written. I thought of using fuser, but it doesn't seem to be very reliable. I vi'd a file in one window and then ran fuser against the file name and got nothing back. I'm just writing a simple bourne script on RHEL.

When I try to launch application which runs in another window (not inside shell), it always fails with this kind of message: (example from gnome-terminal)
Code:
** (gnome-terminal:2477): WARNING **: Failed to connect to the session manager: None of the authentication protocols specified are supported Failed to get the session bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
Falling back to non-factory mode. Failed to summon the GConf demon; exiting. Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon. See [URL] for information. (Details - 1: Failed to get connection to session: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.) I am running it as root, have GNOME installed and running, and also fresh install of gconf.

I've created a simple script based menu. This menu will be accessed by only a certain users via ssh.When user logs in, the menu will automatically run. (configured at user's .bash_profile).How do I force the session to close when user hits Ctrl-C or Ctrl-Break ?In a nutshell, I don't want user to have access to shell.

I wrote a test program to get the CPU utilisation. I hope to extend it to take cpu utilisation on multi core machines. Hear I used the equation for taking cpu utilisation given at [url] of JmSchanck post. But when I match the output of my program against 'top' and 'system monitor' output it seems quite high. Sometimes cpu utilisation goes more than 100%.
So the given equation in that url is correct? can anyone give me the equation to take CPU utilisation?

I am trying to use a shell script to find a string in a file and do something when found. code...
What should happen is pppd will start in a different process and stream it's output to pppdout. pppdout should be created in the current folder. Then the script should periodically check the pppdout file for the string Script (which eventually will appear, some seconds later) and when found exit the script. Ultimately the script will do something useful when the text is found. However, the output from the program is a repeating: 'scriptname.sh: 12: FOUND: not found'
Where scriptname.sh would be the name of your script and 12 refers to the line with 'done'.
Why does grep not find the text, or at least why deos my script not check the grep output correctly?

I wanted to make some modifications to a Kate plugin, so I cloned the git repository, started doing a few changes, and it compiled. The problem is that when I run it, it uses the version of the plugin installed in the system, not the one compiled with Kate.

I've recently upgraded to gnome shell in experimental, and I like it so far. However, the window borders and themes look like how Gnome 2 did before you install gtk2-engines and some themes. Are there any themes in the repositories that I'm missing, or are they just not there yet?

I am using Linux on my system. I don't have gui for my system, only console is there.
I have some task to create a menu box window using dialog in shell scripting.
I have to take input from user & save it in a file.
But this should like html form as e.g.
Name - .....................
email id - ..................
phone - ......................
location - ...................
Submit Cancel
Such window should be displayed on console using dialog & then user will enter his information there as Name,email id, phone,etc & submit it, then it gets saved to a file. Here submit & cancle are buttons. I have to do it in bash shell scripting. Or give me some examples like the above with shell script code.

I started to run a C++ my program in Linux and I don't know how to test my program that works fine with a text file. This is a project for my uni and to explain more clear, My program is a sample database for modify or add and search and it read data from a binary file and also write into a binary file. I have got an input from my lecture and she said after compiling in Linux I must write:
1-to compile:
Code:
g++ (files with cpp)
2-to see the output:
Code:
./a.out
3-to test with input:
Code:
./a.out < input.txt >
My problem is in step three. What I must write in the command part after" step2" to see the output?

I ran a perl script in background with nohup and disown to make sure my script runs even after the parent process is terminated.
Method 1: nohup
> nohup perl run.pl &
[1] 2080
Method 2: disown
> perl run.pl &
[2] 2448
> disown
In either method, the script process doesn't seem to connect to init process, when I checked using pstree command. I thought, the disown or nohup command detaches the process from its parent and attaches it to grand grand parent init process. And it disables SIGHUP signal to my script process. But the pstree command didn't show me what I expected. It still shows my script process attached to my current terminal process. I just don't understand the concept behind these two commands (nohup and disown). Is there any way, I can see the list of processes that are run by nohup or disown command?
