How can I undo a terminal command?

I have altered the default location of screenshots taken on my iMac. Origionally the screenshots were sent to my desktop.
I created a folder and named it screenshots. I then opened a terminal screen which was found in the finder, under utilities. Then I copied the following into the command line "defaults write com.apple.screencapture location". Then before clicking return, I dragged the folder I named "screenshots" into the terminal window. Then I typed "killall SystemUIServer" to reset the terminal and the changes took effect.
I am curious now, how to undo these changes if I want to?

I don't believe you are using a PPC iMac, so you may want to change your profile configuration to include all the information about your hardware.
A good utility for doing these types of configurations without the need to know Terminal commands is MacPilot 4.3.1.

How do I Undo This Terminal Command?

defaults write com.apple.Safari NSQuitAlwaysKeepsWindows -int 0
thats the exact termial command i used. Any help would be great! Ive Tried using different commands to counteract this one but i have no idea what im doing.
- Im running lion
- i got the brand new macbook pro
- any help would be awesome!

Obligatory warning: If you mess around with the shell without knowing what you're doing, you will cause yourself big trouble. You were lucky this time. Many shell commands can't be reversed so easily, if at all.

Can I undo iChat Terminal command?

Entered "com.apple.ichat newbwdup 300000" on an iBook running 10.3.9 not realizing that that was only for Panther. Now it cannot connect to the internet or open iChat. Is there anything that can be done other than reinstall?

Run the following command:
defaults delete com.apple.iChat newbwdup

How can I send multiple string commands into a VISA write?

Hi Fellow LabVIEW users
I am very new to LabVIEW (2.5 months) so please forgive me if my lingo is not up to par.
How can I send multiple string commands to a VISA write. For example each string command looks like this
1) 3A00 0000 0000 FFFF FFFF FFFF 0000 0000 FF00 0000 0000 0000 0000 0033 (Scenario 1)
2) 3A01 0000 0000 FFFF FFFF FFFF 0000 0000 FF00 0000 0000 0000 0000 0034 (Scenario 2)
3) 3A01 0000 0000 33FF FFFF FFFF 0000 0000 FF00 0000 0000 0000 0000 0067 (Scenario 3).
and so on and so forth. And there are a number of scenarios.
Each String scenario will give a different string output which will be interpreted differently in the front panel.
Right now I have to manually change the string commands on the front panel to give me the desired output. How can I do this without manually changing the commands i.e. hard coding each scenario into the block diagram?
Thanks, any feedback will help.

How can I undo an add-on settings sync?

I use Firefox Sync. As far as I can tell, bookmarks synced well. Tabs didn’t but that’s probably due to having opened to many on my main machine. Also add-ons synced i. e. the Firefox on a Ubuntu laptop now has all the add-ons that my home computer Firefox has. Unfortunately, the sync reset all of the settings in some add-ons. So, for example, in LeechBlock the list of websites that I’d like to block, the schedule and all the rules are gone. How can I undo the last sync? Or is there a way to make my main computer the master in all syncs?

The prefs that are set by an extension are usually not included in the Sync, so you get the default setting if you sync an extension from one computer to another.
Only prefs that have a corresponding services.sync.prefs.sync.* pref that is set to true will be synced to other devices.
If you want to sync additional prefs then you can create a corresponding Boolean sync pref yourself and set the value to true.
* services.sync.prefs.sync. (with the pref name appended no space after the last dot)

After getting an update from 10.6.8 many of my programs were no longer able to open. How can I undo the update or solve this problem another way?

After getting an update from 10.6.8 many of my programs were no longer able to open. How can I undo the update or solve this problem another way?

Do you have a bootable clone from prior to the update? If so, roll back with that.
Are your apps that won't open PPC and do they need Rosetta? Do you need to activate Rosetta?
Have you considered reinstalling 10.6 from your install disc and then coming forward with the 10.6.8 Combo Updater, then doing software update and not including whatever it was you installed that caused this propblem?
By the way - what update was it that caused this problem?

How can I run Runtime.exec command in Java To invoke several other javas?

Dear Friends:
I met a problem when I want to use a Java program to run other java processes by Runtime.exec command,
How can I run Runtime.exec command in Java To invoke several other java processes??
see code below,
I want to use HelloHappyCall to call both HappyHoliday.java and HellowWorld.java,
[1]. main program,

class HelloHappyCall
     public static void main(String[] args){
          try
               Runtime.getRuntime().exec("java -version");
               Runtime.getRuntime().exec("cmd /c java HelloWorld "); // here start will create a new process..
               System.out.println("Never mind abt the bach file execution...");
          catch(Exception ex)
               System.out.println("Exception occured: " + ex);

Thanks a lot..

Thanks,
But How can I see both programs printout
"Happy Holiday"
and
"Hello World"
??First of all, you're not even calling the Happy Holiday one. If you want it to do something, you have to invoke it.
And by the way, in your comments, you mention that in one case, a new process is created. Actually, new processes are created each time you call Runtime.exec.
Anyway, if you want the output from the processes, you read it using getInputStream from the Process class. In fact, you really should read that stream anyway (read that URL I sent you to find out why).
If you want to print that output to the screen, then do so as you'd print anything to the screen.
in notepad HelloWorld.java, I can see it is opened,
but in Java, not.I have no idea what you're saying here. It's not relevant whether a source code file is opened in Notepad, when running a program.

How can I customize my terminal?[SOLVED]

I'm using xterm and /bin/zsh, but it looks ugly. It's a white background with a black text. On debian, I use to right click and hit preferences and went from there. But when I right click it just highlights the shell. How can I customize background color, change font, etc?

He/she lists everything they are using right under the screenshot:
Much of the same from my other submission...
Arch Linux with Awesome WM and custom tile layout. Also using Compton for composition.
Firefox Nightly (Australis) [v31.0a1] and 4-Chan with my CSS. Using Vimperator for navigation.
(Firefox CSS can also place an url-bar on top (below the tabs or merged with the tabs on the left) or at the bottom of the browser)
Terminals (URxvt-256color) showing from left: screenfetch and ncmpcpp + mpd.
My files can be found at twily.info (files updated for this theme May 17th, 2014)
The Lemon font and my vol/bat widgets belong to github.com/phallus.

If I was you, I would go through each thing listed and figure out each one. Understanding each element is essential.

How can I undo the deleting of a calendar?

How can I undo the accidental deleting of a calendar within the ipad calendar program? How can I generally undo things I did within the ipad programs?

Hi,
Per my understanding, you might want to check if there any overlapped recurring events in Event Receiver.
You can build the query with <DateRangesOverlap> to return the recurring events with Server Object Model.
A code demo in the thread below about how to get recurring events from Calendar for your reference:
