Read all LVM files in a folder and compile

Hello

I want to read all the LVM files in a folder as shown in Figure 1. In each file LVM, there is a row of data that are important, like on the picture 2. I want to extract only the rank of value in all the files this particular file LVM.

Then I want to compile in 1 Excel or text file.

Furthermore, I also want to name each line values in newly compile it files. The name will be the name of the file extracted it previously, as well as the date and the time it was created.

I tried to use the loop and the folder list, but to no avail.

Hope that this will not be a too much trouble. Thank you

Hi pengxin,.

What room are you stuck at?

Below is a diagram of simple block that I created which should do what you need. First of all, we get all the names of individual files, and then one by one, we read the data from the file. Since you only need the data in the first row, we will index in the array, add the name of the file, the date and time of last modification of the file to the front of the data, and then save them in a new file.

I hope this helps.

Kind regards

    Hi chrism43238735,

    May I know the process to convert Doc to PDF files. If you use Acrobat to convert the files, and then with the same application you open.

    If you used another process, in this case try using the Adobe Acrobat Reader application. Adobe - Adobe Acrobat Reader DC Distribution

    You must wipe the drive and reinstall OS X. In the future, you need to stay away from the data in the system until you know what it is and the consequences of the removal.

    Install or reinstall OS X from scratch

    Make sure that you have backed up your files because the following procedure will remove all of the hard drive.

    HD recovery start:

    Restart the computer after the ring, press in and hold the COMMAND and R keys until the menu screen to appear.

    Erase the drive:

    1. select in the main menu disk utility and click on the continue button.

    2. once the charges of THE select your boot volume (usually Macintosh HD) in the

    list on the left. Click on the Erase tab in the main window of THE.

    3. set the type of format Mac OS extended (journaled). If necessary, click

    Security and button all the option data from scratch in a single pass. Click

    the clear button and wait until the process is complete.

    4 leave FROM and return to the main menu.

    Reinstall OS X: Select reinstall OS X and click on the install button.

    Note : You will need an active Internet connection. I suggest to use Ethernet if possible

    because it is three times faster than wireless.

    This should install the version of Mac OS X that you had installed it.

  • How to print all the files in a folder without having to open each one?

    Hello

    Can someone tell me how to print all the files in a folder? I often need to print multiple files in a folder and it would allow me to save a lot of time!

    Thank you!

    I've done some testing, and it seems that Windows 7 allows print several files when they are all the same type of file.  So, for example, you can select and print 15 Word documents, but not a Word document and a single PDF document.

    To work around this limitation, you can print each file type separately.  For example, to print PDF files in a folder:

    1. Type *. PDF in the search for top-right box.
    2. For 1-15 files, press on CTRL + A to select all the.
    3. For 16 or more files, select 15 of them (click on the first, SHIFT + click the last).
    4. Click any file, and then click print .
    5. Repeat steps 3 and 4 as needed.

  • Order findstr/l/s/m print the file names of all the files in the directories and subdirectories despite any string contained

    Hello

    I'm looking for a file via the findstr command. After that I opened the command as Administrator window, I get:

    Findstr/l/s/m 'a string containing the words. " *

    Then, the command window displays all the files in the directory and its subdirectories. I think that I see which file is searched for the chain in real time.

    I expected to see only the name of the file/s if the string was found in it.

    What I am doing wrong? or why is this malcfunctionaning?

    I got directions for ordering findstr here: https://technet.microsoft.com/en-us/library/bb490907.aspx

    Thank you

    I think you want the /c parameter instead a / l.  As written, your search string is interpreted as a list of strings: 'a', 'string', 'with' and 'words '.  Any file that contains an 'a' will be a return match.  The parameter/l keeps your strings to be interpreted as regular expressions.

    If you need exactly match to the entire chain, type:

    Findstr /s/m/c: "a string containing the words." *

    Under the direction of add: It is not clear, but you can have several settings/c , to search for more than one exact string at a time.  For example:

    / s/m/c: 'a string' findstr / c: "a Word." *

    Research is 'a string' or 'a word' exactly.

    Hello

    It is a limitation of UTL_FILE in Oracle that we can do with Java stored procedures in Oracle.

    We can read the files in Server directory using the following steps:

    Please follow the steps below:

    1. creating a Type of Type Varchar2.

      CREATE OR REPLACE TYPE file_list AS TABLE OF VARCHAR2(255);
    

    2. next, we need create a library of Java file

    CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "ListVirtualDirectory" AS
      import java.io.*;
      import java.security.AccessControlException;
      import java.sql.*;
      import oracle.sql.driver.*;
      import oracle.sql.ArrayDescriptor;
      import oracle.sql.ARRAY;
    
      public class ListVirtualDirectory {
        public static ARRAY getList(String path) throws SQLException, AccessControlException {
    
        Connection conn = DriverManager.getConnection("jdbc:default:connection:");
    
        File directory = new File(path);
    
        ArrayDescriptor arrayDescriptor = new ArrayDescriptor("FILE_LIST",conn);
    
        ARRAY listed = new ARRAY(arrayDescriptor,conn,((Object[])directory.list()));
      return listed; }}
    

    The most advanced method overrides by removing information about java.properties of exception management settings. You can do this by catching the exception thrown in native mode and rethrow it or ignore it. The example it up again.

    3. then, you must create a Wrapper function:

    CREATE OR REPLACE FUNCTION list_files(path VARCHAR2) RETURN FILE_LIST IS
    LANGUAGE JAVA
    NAME 'ListVirtualDirectory.getList(java.lang.String) return oracle.sql.ARRAY';
    

    4 grant permissions to the Driectory:

    BEGIN
      DBMS_JAVA.GRANT_PERMISSION('USER_NAME'
                                 ,'SYS:java.io.FilePermission'
                                 ,'C:\JavaDev\images'
                                 ,'read');
      END;
    

    5. then you can read the contents of the directory

    SELECT column_value FROM TABLE(list_files('C:\JavaDev\images'));
    

    That displays all the files in the mentioned directory.

    Thank you

  • I used "Show Hidden Files" in a folder and all my files disspeared

    I used "Show Hidden Files" in a folder on an external hard drive and all my files disappeared after I changed the settings and press ENTER.

    I also made the change not in a folder, but the subfolders. I have many files duplicate on my external hard drive and I noticed that each file said that she had more files that were contained in each file, so I wanted to see what were these hidden files. After you have clicked on enter, each music file and folder just disappeared.

    I searched my pc but can't find these files. I got more than $ 100 of music who has simply disappeared.

    What can I do b/call, the music were in a separate folder, and there were more than 50 files with hundreds of songs. I mean how to do a cover for it?

    Return to the folder options and use the "Restore default settings" button to change all the options back how they were, and see if it helps.

    You can also try to use the drive in another computer, if you think that the configuration of your computer could be the problem.
