Appending timestamp to the dumpfile. Why do we need this space ?

11.2.0.3/RHEL 5.4
When running expdp in Linux , I was trying to append the timestamp to the dumpfile and the following syntax has worked.
DUMPFILE= PCFS_SIT-`date '+%d-%b-%Y'`_%u.dmpThere should be a space after the date keyword. Without the space you'll get the following error
$ -ksh: date+%d-%b-%Y: not found [No such file or directory]Why is this ?

    All I want is all my contacts on my phone and the same on my iMac, but no, that's too much to ask, instead I get everything doubled up on the phone and everything doubled up (triple in some cases) on the iMac, why does it do this? and more importantly how can I stop it? Thanks

    Look under system preferences on the mac at what is be controlled?  Look at Mail, Contacts, Calendars.  How many accounts are managing contacts?  Just the cloud? the cloud and gmail? or cloud, gmail, yahoo, and exchange?  If you have more than one contact account, then you will have different contact lists, if John Smith shows up in more than one of your contact lists, you will have multiple entries.
    Pick a contact list that is your master, (I use iCloud), only turn on contact syncing for it.  The same for your phone.  Spend some time on the iCloud webset (www.icloud.com) and work on your contact list there.  Clean it up, remove duplicates, etc...Changes will auto sync back to all your devices.  Life gets much simplier.
    Just remember, if you sync different contacts lists and a large number of people appear in your different lists, then they will appear as duplicates.

  • HT4221 I really want my Apple TV, iPad and iPhone to sort them in date taken like in iPhoto on my iMac. How do I do that? Sorting on date modified seems so stupid to me, why would anyone need this? Date taken gives a timeline in your event.

    The unix commands you need are:
    GetFileInfo
    SetFileInfo
    and maybe find
    for cryptic details use the man command
    Macintosh-HD -> Applications -> Utilities -> Terminal
    man SetFileInfo
    You may use the SetFileInfo command to set the file type & the program which will open the file.
    # This little gem will do a get info on all files in a directory.
    mac $ ls  | xargs -I {} GetFileInfo "{}"

    The date they were taken us in the EXIF data and is included in the export

  • In ITunes when I'm using home sharing if I play the songs on another computer it cuts the songs off maybe 10 seconds plus from the end why is it doing this?

    So I have ITunes Home Sharing on my desktop computer on.  When I go to another computer and play the songs from the Home Share computer the songs get cut off maybe 10 seconds + at the end of the song.  In other words it will not play the last 10 seconds of the song sometimes it's last 5 seconds sometimes its the last 15 seconds it seems to vary.  I can't really find a pattern on the timing but I just don't understand why this is happening please help!

    Delete and redownload them if doing so is free in your country.

  • There is always an error installing the ios, why? I need help, ty

    Why is it that there is always an error in installing the ios update 6.0.1. I need help. Ty

    What iOS are you currently running?
    If you have an iPad 1, the max iOS is 5.1.1. For newer iPads, the current iOS is 6.0.1. For the iPad Mini the iOS is 6.0.2. The Settings>General>Software Update only appears if you have iOS 5.0 or higher currently installed.

    iOS: How to update your iPhone, iPad, or iPod touch
    http://support.apple.com/kb/HT4623
    If you are currently running an iOS lower than 5.0, connect the iPad to the computer, open iTunes. Then select the iPad under the Devices heading on the left, click on the Summary tab and then click on Check for Update.
    Tip - If connected to your computer, you may need to disable your firewall and anitvirus software temporarily.  Then download and install the iOS update. Be sure and backup your iPad before the iOS update. After you update an iPad (except iPad 1) to iOS 6.x, the next update can be installed via wifi (i.e., not connected to your computer).

  • Why can't I use the internet, why do I need Wi-Fi

    I don't have Wi-Fi in my place, I don have internet. Why can't I connect my Ipod to the internet to download my updates on
    my applications

    Yes, you can download the updated apps on your syncing computer and then sync the iPod with your iTunes library. Note that you can only sync apps on the one syncing computer you can have.

  • I keep getting a message about video player update. What's going on? Why do I need this? Prove that I do - too many viruses out there to just download something

    A page keeps popping up saying FIREFOX wants me to download this video player. I'm leery of downloading anything these days with the Heartbleed virus out there

    If you get a pop-up message asking to update or install other software then such a message is likely a scam and you should never respond to such an alert to avoid getting infected with malware.
    You should only update Firefox via "Help > About" or by downloading and installing Firefox from the Mozilla server and never via a pop-up or link on a web page.

  • [T41] Why do I need this piece on my motherboard?

    Making some maintenance, I found a piece of electronics hanging loosely from the motherboard which fell out with little effort.
    I took a picture of the piece and the location where it originally was:
    http://www.catvalley.cl/media/4.jpg
    Question is: What was that piece for? Mi laptop appears to be working normally. The only problems are the problems that it already had: Screen flickering (LCD pannel turns on and off repeatedly) when using graphic-intensive applications (like watching videos fullscreen) and USB ports working as USB 1.0.
    Is it safe to still use my laptop?

    It is a capacitor, but without a circuit diagram, it is hard to tell what is the function. The board is old enough that it will be leaded solder, so you won't need much in the way of equipment. If you know anyone with a decent soldering iron, I would suggest putting it back onto the pads

  • Does anyone have problems with their mac having a Medium-write error? Mine is totally out of hand... I have wasted countless CDs, I've purchased the Mac CDs, and I have tried to minimize the burn speed... The problem continues, and I need this for work.

    My mac keeps saying medium-write error, and it's become out of hand. I've done all the suggested things to prevent it, by buying apple CDs, minimizing the burn speed, and restarting my computer... I need to burn CDs for my job, and I am a firm apple supporter... This is just out of control it took me 90 mins to finally burn a CD, because I had to go through 10 other CDs... HELP.

    I doubt they're any better than anything else.
    I may have an Apple CD-R around here somewhere...

  • Why do I need more space?

    I received an email saying my free iCloud is almost full. However, checking my System Preferences on this Mac, I see I have 24.99 of 25 GB available. My iPhone, however, shows I only have 5 GB and most of it is used. Apparently, I have to buy an iCloud account on each device; that seems counterproductive, so probably it's my mistake.
    What am I doing wrong?

    No, you do not separate accounts for your devices. It makes more sense to only use one account for all your devices in order to sync data like contacts, calendar events, reminders, notes and also app data between them.

  • SSRS 2008 - Append timestamp in filename for email delivery

    i need to append timestamp in the filename which i am attaching to send report in email
    suggest solution other than fileshare

    Hi,
    As you can see, we can use a variable to get dynamic FileName for the report or attachment only when the subscription is using Windows File Share delivery extension. However, you can implement a custom delivery extension to achieve your goal, please see:
    http://msdn.microsoft.com/en-us/library/ms154050.aspx
    Besides, you can refer to the Printer Delivery Extension Sample provided by SQL Server Reporting Services Samples:
