View 1 RepliesWithin PyGTK I'm using gobject.spawn_async to launch a bash script. I would like the output of that bash script to be displayed within my application. I have a textview set up to receive the text ...
Here are the commands that launch the program:
Code:
def run_command(command):
global keep_pulsing
keep_pulsing=True
(cpid, cstdin, cstdout, cstderr) = gobject.spawn_async(command,flags=gobject.SPAWN_DO_NOT_REAP_CHILD|gobject.SPAWN_STDERR_TO_DEV_NULL,standard_code....
Here are the two callback functions. But like I say ... I have no idea how to get that data from the 'cstdout' file descriptor into a textbuffer.
Code:
### THE FOLLOWING ARE GLOBALS:
textview = wTree.get_widget('textview1')
textbuffer=textview.get_buffer()
def update_textview_callback(fd, condition):
global keep_pulsing
if keep_pulsing:
progressbar.pulse()
code....
When I add text to the TextView object it expands the parent window rather than adding scroll bars. How do I fix this?
I want to keep the parent window user re-sizeable.

i have a host file called myhosts.txt as follow:
Quote:
10.20.3.9 host1
10.20.3.10 host2
10.20.3.11 host3
[code]...
In my script, i am using NSLOOKUP to get the ip address of a host that just rebooted and connected to my network (this part has been done).But now i want to check the myhosts.txt file if the host has the same or different IP address, if is different then myhosts.txt file must be updated with the new IP.i am using the following AWk command:
Quote:
awk '/host4/{$1=val}{print}' val=10.0.3.4 /tmp/myhosts.txt
it prints on screen fine and i see the host4's ip address gets replaced but the actual file does not get updated with the new IP. I might need to use gsub?
I have written a daemon server. I would like to add the ability for the daemon to update itself. That is, it should be able to download the latest version of the code (when it receives a signal from a client) and then restart itself. I am stuck on getting the daemon to restart itself. The problem is killing the old daemon without killing the process that is starting the new daemon. In my latest attempt, the daemon that is updating itself runs a program in a subshell (using system) that starts a restarter daemon that runs the original daemon (again using system) with the restart command option. With the restart option, the new version of the daemon sends a terminate signal to the old version. Obviously, when I run the original daemon manually with the restart option, it restarts reliably. I figured that issuing the same restart command from a daemon would adequately isolate the process doing the restarting from the program being restarted. Using ps, I can see that the daemon does actually restart. However, the client locks. In fact, a few times, the OS locked and I had to reset.

What I need to do is find all lines beginning with ^To: and put a comma between a random number of names on this To: line. So I want to replace the 2nd and all subsequent <space> on this lines with ,<space>.
It should be something like:
s/^To: [ ]/&,/2g

I need help getting this bourne shell script working properly. This script I found online while reading some tutorials on getting a caching name server running, which is supposed to update the rootserver hints file.
The below case statement always returns that the hints file has failed. Even though when I check the file it looks normal and I can see the NOERROR status in the returned header.
Code: dig (at)e.root-servers.net . ns >root.hints.new 2> errors
case `cat root.hints.new` in
*NOERROR*)

Provided this example code with a few givens:

$params=array($newname,$newnumber,$oldnumber);$new_result=pg_query_params($db,"UPDATE mytable SET name=$1, number=$2 WHERE number=$3",$params);$new_number_rows=pg_affected_rows($new_result);
I get an error, and when looking on the database end I the query with the $1 $2 and $3 instead of assigned values; pg_last_error() shows: Quote: ERROR: syntax error at or near "WHERE" LINE 1: WHERE number=$3 ^

View 7 Replies View RelatedI'm pretty new subversion, and have a basic question which I haven't found the answer to:Say that I on machine A modify the working copy of my code, create a tag "release-1.0", and commit it, how can I on machine B point the working copy to the tagged code? For example, say my "code" is actually config files for Apache, and I wan't apache running on machine B to update it's config files based on the files found in tag "release-1.0", how is this done?
I'm sure the solution is very easy, but I just can wrap my head around it.
I've been thinking to adding the ability to update some code I've been working on from the internet. So basically writing some C/C++ code that on startup of the software looks across the next to a server to update itself. However I have no idea how to do this, can anyone point to to linux tutorials or examples which show how to do this?

View 2 Replies View RelatedI am trying to automate yum update of specific package on a remote machine. Essentially, the script executes, does a yum update, if not needed it would return echo result "update successful", if it needs the update and it installs it without error, it will return echo result "update successful", or if it fails the update it would echo "update failed". So far I have this:

I am trying to update using Update Manager and I get this message: Failed to fetch "Failed to fetch [URL]..404 Not Found" My system is 64 days out of date now.
I have looked elsewhere for an answer and some others have had similar problems, but I have not found a reason for it happening, nor an answer. I wonder if anyone can help me please. I have been using Ubuntu for several months, can use the Terminal if I have the right commands to issue, but beyond that have limited knowledge of the system.
As the title says i updated my system which then needed a reboot. I also installed Mixxx djing software to try it out. So i thought id just restart the system. Usually when i boot into my desktop wireless automatically can connect to my router but not this time, wired only for now... i know theres tons of wireless issue threads but some more experienced users will be able to get straight to the point and run through some diagnostics with me.

I have logged in today and update manager reminds me of an update with linx-backports-module-2.6.31-14-generic. However my current kernel has been updated a while ago and is now 2.6.31-17. That obviously is more recent that that backport version. What should i do? By the way that update is from a PPA repository other that the default. I am wondering the update manager has no way to tell which kernel version i have at all? Should i actually go ahead with the installation?

After downloading almost 95% of the update, it gave an error message of "could not download certain components. downloaded files will not be erased" and stopped the update. I restarted the PC, and started the update manager again. But now it does not show any option of update to 10.4. how do I continue or resume the update process? I just started using ubuntu about 15 days back. So, I am relatively new to this.
