Thanks in advance

What do you mean "included during installation of a specific app"? The only packages installed with a target package are those packages which it depends on, so you can't remove them if you want the target package to still work. To remove packages that you don't want anymore, use "pacman -Rsn <pkg name>". That will remove the package and it's dependencies.
To see which packages are "orphans", i.e. installed as dependencies for packages that are no longer installed, use "pacman -Qdt". You can remove all of those with "pacman -Rsn $(pacman -Qqdt)".
Take a look at the pacman man page too: "man pacman"
EDIT
I just saw your post here where you state that you've been making packages with
makepkg -s
Now I understand what you want to remove and why. The "pacman -Rsn $(pacman -Qqdt)" command will do this.
In general though, you should take the time to learn about the utilities that you're using. From the makepkg man page:
-r, --rmdeps
Upon successful build, remove any dependencies installed by makepkg
during dependency auto-resolution (using -b or -s).
-s, --syncdeps
Install missing dependencies using pacman. When build-time or
run-time dependencies are not found, pacman will try to resolve
them. If successful, the missing packages will be downloaded and
installed.
Instead of using "makepkg -s", you should use "makepkg -s -r" to remove makedepends automatically when you're done.

How to deploy and remove one application from WebLogic server

Dear Friend:
Do you know anyway that I can deploy or remove an application using
command line intead of administration console when the WebLogic
server is running?
Thanks in advance,
Damon

I think we have to clean ( already scheduled for next release) list of some of the
supported API on various MBeans. However just FYI , there is an "void
setURI(java.lang.String)" method in Component MBean that you could use.

I am also trying to automate application deployment process. I have looked at
the docs you suggested below and am wondering why the ComponentMBean has a getURI()
but not a setURI().
Here's a snippet from my config.xml that I want to automate:
<Application
Deployed="true"
Name="TestApp1"
Path="E:\WebApps\version1">
<WebAppComponent
Name="TestApp1"
URI="TestApp"
Targets="myserver"
/>
</Application>
I haven't figured out how to set the URI.
Also, it looks like this should also be possible using weblogic.Admin. Is that
true?
Thanks,

How can I enable java applet plug-in and Web Start applications via terminal?

Since the last Java update to Snow Leopard, I have found that the system periodically disables the Java applet plug-in after a period of disuse. I know I can go to /Applications/Utilities/Java Preferences and just click to re-enable Java. But I want to write a script which will do this periodically for a couple hundred Mac users where I work.
My question is - how can I reenable the Java applet plug-in and web start applications via Terminal command? Is this possible? Is there a plist file that can be modified, etc.?
Bob Reed

It is my understanding that Apple's most recent Java update automatically disables Java after a certain period of time that it hasn't been used. We don't want users to have to keep re-enabling it. So we wanted to find a way to do this via script either run by a Casper JSS server or stored locally on each workstation.   With the guidance provided by Mark Jalbert above and some text from a script written by Rich Trouton, I was able to make a script (with some minor changes) and a launch agent to re-run the script upon login. So the preference is always enabled.
For your reference, the script content is:
#!/bin/sh
# DYNAMICALLY SET THE UUID FOR THE BYHOST FILE NAMING
if [[ `ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-50` == "00000000-0000-1000-8000-" ]]; then
MAC_UUID=`ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c51-62 | awk {'print tolower()'}`
elif [[ `ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-50` != "00000000-0000-1000-8000-" ]]; then
MAC_UUID=`ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-62`
fi
# Set the the "Enable applet plug-in and Web Start Applications" setting in the Java Preferences for the current user.
/usr/libexec/PlistBuddy -c "Delete :GeneralByTask:Any:WebComponentsEnabled" /Users/$USER/Library/Preferences/ByHost/com.apple.java.JavaPreferences.${MAC_UU ID}.plist

The launch agent plist content is:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

          <true/>

How to streamline and remove duplicate files on my HD before I backup?

I should know better than having a Drive that is not perfectly organized
I think there is something called SpringCleaning for windows
is there something like this for Mac?

You should back up your drive with Time Machine before you delete any files in case you make a mistake.

Click on the Time Machine browser icon on the dock. Locate the duplicate file you wish to delete and highlight it. Click on the button with the gear on and choose Delete "all backups of".

How can detect and remove scanned white pages in an OCRd pdf file?

How can detect and remove scanned white pages in an OCRd pdf file?

Acrobat does not support an automated way of doing this directly. You can
remove completely blank pages (pages that don't have any "marking
objects"), but a scanned page does contain an image, so Acrobat won't help
you here. There are a number of 3rd party applications and plug-ins
available. Try a Google search for
remove blank pages from scanned
pdf<http://www.google.com/search?client=safari&rls=en&q=removeblankpagesfromscanned+pdf&ie=UTF-8&oe=UTF-8>
This will bring up a few different solutions.
Another way is to use JavaScript to find text. You say that these documents
are OCRed, so if you have a blank page, it should not have any text on it.
With some JavaScript, you can identify pages that don't contain text. This
may however fail if you have a page that contains just e.g. a photographic
image. There won't be any text, but the page is certainly not blank.

HT2905 No Display Duplicates under File. How to find and remove duplicate items in your iTunes library

I now have iTunes ver 11.0.4.4 under Windows 7. I lost all iTunes stuff when updating to Windows 7. I have loaded thousands amd thousands of music files from backup disks, but there are many duplicates. I am attemping to re-establish my old library. I used to be able to remove duplicates quickly with the old iTunes. The new iTunes doesn't seem to offer the same service. Is there any way to remove duplicates quickly, or must I do it one by one?

When deduping use Shift > View > Show Exact Duplicate Items as this is normally a more useful selection. You need to manually select all but one of each group to remove. Sorting the list by Date Added may make it easier to select the appropriate tracks. If you have multiple entries in iTunes connected to the same file on the hard drive then don't send to the recycle bin. Use my DeDuper script if you're not sure, don't want to do it by hand, or want to preserve ratings, play counts and playlist membership. See this thread for background and please take note of the warning to backup your library before deduping.
(If you don't see the menu bar press ALT to show it temporarily or CTRL+B to keep it displayed)

How to stop and remove an active job.

How to stop and remove an active job.

What sort of "job" are you referring to? A print job? If so, open the queue for the printer - it should be in your Dock, or you can access it through the Printers & Scanners system preference - and click the green Pause button to stop the entire queue, or the Pause button next to a specific print job to pause just that job. To clear a job, click the "X" button to the right of the job.
If that's not the "job" you mean, please post back and clarify.

How to design and implement an application that reads a string from the ...

How to design and implement an application that reads a string from the user and prints it one character per line???

This is so trivial that it barely deserves the words "design" or "application".
You can use java.util.Scanner to get user input from the command line.
You can use String.getChars to convert a String into an array of characters.
You can use a loop to get all the characters individually.
You can use System.out.println to print data on its own line.
Good luck on your homework.

A good book to start with is Enterprise JavaBeans by Monson-Haefel (O'Reilly press). It covers deployment of EJBs on J2EE servers. Also check out sites specific to your server, sometimes they have specific requirements (like Weblogic).

Hi,
You can use: startManagedWebLogic.sh, it is in your domain directory and you have to execute it in this way
./startManagedWebLogic.sh managedServerName http://adminServerHost:adminServerPort
For instance, in my case I use:
unixserv01:/webportal/domains/appServerWeb/bin>startManagedWebLogic.sh managedServ01 http://pelma3w3per01.mesaperu.next:7001
You have to run it on the machine where the managed server was installed.

How to find and remove obsolete table entries from /SAPAPO/MATKEY table in EWM System.

Thank you,

Pravin,
First, tell me how you determine that these entries are 'obsolete'.
Removing master data from SCM can usually be done using transaction WUF; however, you have to ensure that it is not re-sent to the SCM system, or you are just wasting your time.
