move the cursor at the beginning of the file (InputStream)

Hello! I read a file (using InputStream) and necessary move the slider at the beginning of the file (to be able to search inside the file, moving at the beginning and then jump bytes). I'm targeting 4.5 OS. Is it possible to do? Can I reopen it the file? (is it slow? is this a bad idea?)

Thank you very much!

Call InputStreamReader.mark (readlimit) in early reading. Then call InputStreamReader.reset () whenever you want to reset the position of the stream of input to its original position, when the brand was called.

  • Move the file in the folder of the same name in AppleScript

    I had a problem with the script below. Basically, on the execution of the script, I want to create folders based on the name of the file and move the files in the files of autocorrelation. However, at the minute, that I'll have to choose the folder in which the script should run.

    Folder to choose a folder

    say application 'Finder '.

    located fileList to the name of every file in Folder with name extension is "m4v".

    end say

    the value point text delimiters to ".".

    Repeat with dittos in list of files

    get each text element of dittos

    masterFile defined in the point 1 of the result

    say application 'Finder '.

    create a new folder to Folder with properties {name: masterFile}

    move (each file from the folder Folder whose name contains masterFile) will cause

    end say

    end Repeat

    Ideally, I would like it to run automatically, but the folder is on an external hard drive. (\Volumes\Lacie\Movies). and I had problems to use the POSIX and 'alias' to properly re-create the path of the file desired.

    Any help would be greatly appreciated. Thank you!

    Hello

    You can try something like the AppleScript script which is a simple shell script wrapper.

    set d to (choose folder)'s POSIX path
    do shell script "/bin/bash -s <<'EOF' - " & d's quoted form & " 2>&1
    cd \"$1\" || exit
    shopt -s nullglob
    for f in *.m4v
    do
        m=${f%.*}
        [[ -d $m ]] || mkdir -p \"$m\" || continue
        mq=$(sed 's/[^[:alnum:]]/\\\\&/g' <<< \"$m\")   # quote meta characters for regex
        find -E . -depth 1 -type f -iregex '.*/'\"$mq\"'.[[:alnum:]]+$' -print0 | xargs -0 -J% mv % \"$m\"
    done
    EOF"
    

    For example, given that you choose/path/to/directory in the folder - source

    Input state:

    /path/to/directory/abc.m4v
    /path/to/directory/abc.txt
    /path/to/directory/abcd.m4v
    /path/to/directory/abcd.txt
    

    Status of the output:

    /path/to/directory/abc/abc.m4v
    /path/to/directory/abc/abc.txt
    /path/to/directory/abcd/abcd.m4v
    /path/to/directory/abcd/abcd.txt
    

    Briefly tested under OS X 10.6.8 but no guarantee of any kind. Please make sure that you have a full backup of the original files and directories before you run this kind of script.

    Good luck

  • I can not move the files to a folder in windows XP, only to copy them, and I get the windows error. This happens on any file or folder.

    I use XP Pro SP 3 and I'm having a problem with moving the files from one folder to another, no matter where the folder or files. If I try to move a file, it crashes and it cannot be opened or used. If I move a folder, then crashes all the contents of the folder, and I can't even open the folder, it tells me access is denied, this nothing else. If I try to delete the file, then I get a prompt to error telling me that the file or folder is not accessible, and that access is denied and "make sure that the disk is not full or write protected." If I try to move the files corrupt in another folder, this time I get the message "Unable to move or replace" the file in question and "make sure that the disk is not full or write protected." If it is a document as a text file, then I can open the file and there is a prompt indicating that access is denied. I can then use the text document and save something, but if I close the document and then try to reopen it, all the changes are lost.
    It is not this problem if I move the files to an external device or disk drive.
    I am running as an administrator.
    Right now, if I need to move a file, I copy it to its destination, which is possible and then delete the original file. With the help of a release program was the only way I could delete these files, which could no longer be used.

    Hello Closrapexa, welcome.

    1. do you have this problem started recently?

    I recommend trying the system restore to bring the system back to a State before the problem started. Try this:
    1. click on START
    2. click on "all programs".
    3. click on "Accessories".
    4. click on "system tools."
    5. click on "system restore."
    6 follow the prompts shown to restore your system to a date before the problem started. Although the system restore does not target the personal data, it is recommended that you back up all data such as music, photos and documents in case something is not bad.

  • How to move the FILE from one place to another and keep "Indexing" have to move to the unknown location so you can't discover its full file path? Windows instructions provide information wrong re: how to do this!

    Make a bunch of audio files, placed in a folder on my desktop. Files initially sent to RealPlayer to burn, but when finished burning CD and went to read a CD, folder got seized by Media Player, 'Indexed' and disappeared from the office. I'm a relatively new computer user, and I need to learn more about file paths, how to view the path FULL of a file on my computer and how to type (create) full path when I need to. The "Indexing" feature seems to erase this lesson for me, and after having spent four hours trying to find Vista instructions on "How to move the file from one place to another", I gave up! Windows 'Help and Support' on my computer gives wrong directions. It states that if I right click on a folder > properties, a dialog box opens with a tab by which I can move my account. There is no tab location here. I found locations tab when right click on the "Mobile" folder, but still no option to "move file". No idea what is the folder "Roaming" or why it's on my computer. I want my audio files in the My Music folder, but this place is "access denied." Don't know how to get the audio file it in any case, but if anyone has any advice, I would be very happy! Thank you. PS - I had no problem moving folders in XP. I don't like the idea that a computer is to decide where to put my files. I want to control where I put my files. I don't like the way search works under Vista. I liked the XP search companion better because, for a computer fool like me, it was really easy to organize and find files and folders and had an option specific to find audio and video file TYPES.

    Here is an article on how to move your personal folders in Vista: http://www.howtogeek.com/howto/windows-vista/moving-your-personal-data-folders-in-windows-vista-the-easy-way/.  If you're talking about the special folders (such as photos, Documents, office...), then here is an article on how to move: http://www.winhelponline.com/articles/95/1/How-to-move-the-special-folders-in-Windows-Vista.html.

    If you have trouble with the search after you move the files, then rebuild the index: http://www.tech-recipes.com/rx/2103/vista_rebuilding_the_search_index/.  Here is an article on how to use Indexing Options in Vista that may be useful for you: http://www.vistax64.com/tutorials/69581-indexing-options.html.

  • Cannot move the files, photos at airport Time Capsule

    Hello

    I want to transfer files, photos of my Time Capsule but I don't see anywhere on my macbook. I think that something I messed up when I was put in place at the time of Christmas trees. I'll start from the beginning. Before I bought my time capsule I was connected to the internet through my wireless router, name: GMZ-83313. After that I bought my Time Capsule I set up and connected to the internet. Problem is that I have 2 networks who I can connect it is: GMZ - 83313 and Daniel Wi - Fi network (finally...) I have three really because I started to play with it more and I have network of Wi - Fi for the 3rd networkDaniel 5 GHz ;(

    I just want to add that yesterday I was able to transfer photos from my time capsule and it showed here where you can see GMZ-83313. Yesterday, it was Ant Time Capsule of Daniel it was working fine.

    I'm lost please help. I have attached a shot of my airport utility screen:

    Click gmz-83313 under the Shared heading in the Finder window

    A folder that represents the Time Capsule... hard drive that is named 'Data', unless you have changed the name... appears in the window on the right

  • Move the files, folders, and applications when you use several desktop computers

    I have configured my MacBook Pro to display several different offices, based on several types of work that I do. I'm having two problems: (1) get the apps in the dock to show only in the dock on specific and (2) workstations, get the files and folders to broadcast only on one specific office.

    Re: (1), I followed the instructions from Apple I found online, but all applications in the dock show in the dock on each other in all cases.

    Re: (2), I don't see a menu or option to specify desktop computers. They're showing on all my workstations, which isn't what I want.

    Thank you in advance for your help!

    The Dock is the same, no matter what you are in office. It cannot be configured to display only the items to come on a computer desktop and other articles on others. It is similarly of the icons. An icon that you put on a desktop will appear in all work positions.

    Now you pouvez specify certain applications appear in specific jobs and this applies to the Finder as well so you can have icons of documents and folders appear on a single desktop computer. Other workstations will all show no icons. If you choose this option, you can then open a window to a folder on the desktop that has the Finder, and then move it to another office.

    Before Apple, desktops implemented, there are several utilities which enabled us to operate more as you want, but unfortunately, they are now gone.
