  • Help Please: How to invoke unix command lines from java?

    I have read past topics. Those are really helpful, but I still haven't got my job done. I tried the following:
    String command1 = "ls -la > ls1.txt";
    Runtime.getRuntime().exec(command1);
    String command2 = "tcsh -c ls -la > ls2.txt";
    Runtime.getRuntime().exec(command2);
    String command4 = "cp keywords.txt copyversion1.txt";
    Runtime.getRuntime().exec(command4);
    String command5 = "tcsh -c cp keywords.txt copyversion2.txt";
    Runtime.getRuntime().exec(command5);
    String command6 = "tcsh -c 'cp keywords.txt copyversion3.txt'";
    Runtime.getRuntime().exec(command6);
    Only "command4" works. Any input will be greatly appreciated.

    Thank you very much Gautam. Your solution certainly works. If you don't mind, I would like to ask you (or anybody who is willing to answer) something else. I am trying to run other types of unix command lines as well. I thought that the format you gave would work for everything. But it doesn't seem so:
    String command1[] = {"tcsh", "-c", "ls -la > ls1.txt "}; // this works as you suggested
    Runtime.getRuntime().exec(command1);
    String command12[] = {"tcsh", "-c", "lynx -dump http://www.yahoo.com > webpage.txt"}; //working fine.
    Runtime.getRuntime().exec(command12);
    String command10[] = {"tcsh", "-c", "ngram-count -text keywords.txt -lm LM10 &"}; //doesn't work
    Runtime.getRuntime().exec(command10);
    String command[] = {"tcsh", "-c", "/u/drspeech/sun4/bin/ngram-count -text keywords.txt -lm LM0 &"}; // doesn't work
    Runtime.getRuntime().exec(command);
    String command13[] = {"tcsh", "-c", "ngc -text keywords.txt -lm LM13"}; // doesn't work
    Runtime.getRuntime().exec(command13);
    String command8 = "ngram-count -text keywords.txt -lm LM8 &"; //doesn't work
    Runtime.getRuntime().exec(command8);
    String command9 = "/u/drspeech/sun4/bin/ngram-count -text keywords.txt -lm LM9 &"; //doesn't work
    Runtime.getRuntime().exec(command9);
    I tried "commandd1" and "command12". Those worked fine. No problemo. However, there's someting else I need to get done for my job; that is "command10". But it just didn't work. I thought maybe, it's because "ngram-count" is not part of the standard UNIX commands. So, I thought I might just add another alias for it in the ".cshrc" file and call it "ngc" instead. Then I tried to call the alias "ngc" instead. But it didn't work also. Then I thought, maybe, I should call it by referencing it from its original directory "/u/drspeech/sun4/bin/ngram-count". That didn't work either. I tried a couple of other combinations. None worked. I would really like to see how to solve this.

  • How to execute unix command in plsql block( urgent)

    Hi All,
    i want rename the unix folder to New name on update non_employee table . So, please give me idea how to use unix command here.... Please suggest me ASAP ... Its urgent
    CREATE or REPLACE TRIGGER NON_EMPLOYEE_AftUpd_trg
    AFTER UPDATE ON NON_EMPLOYEE
    FOR EACH ROW
    BEGIN
    IF :new.DIST_LIVELINK_PATH <> :old.DIST_LIVELINK_PATH THEN
    rename unixfolder1 to :new.dist_livelink_path.
    end IF;
    END;

    The solution will depend a lot on your Oracle version, which you forgot to mention ;)
    btw shouldn't that be (in pseudocode)
    rename :old.dist_livelink_path to :new.dist_livelink_pathotherwise it will always fail after the first time?
    In Unix that would require the mv command.

  • Looking to run unix command line from Finder

    I want to run a unix command directly from finder. Kind of like using command-G to "Go To Folder".
    If a current method isn't supported, I noticed that Terminal.app has a shortcut for "New Command" using command-N. What would be the right way to create a keyboard shortcut in Finder that would call Terminal->New Command?
    Thanks

    You might use a third-party macro expansion utility that permits creating keyboard macro shortcuts. Examples include QuicKey or iKey. There are also several text expansion utilities that also allow attaching keyboard shortcuts such as TextExpander or Typinator. The above can be found at VersionTracker or MacUpdate.
    You can also create an AppleScript using the Do Shell Script command. The resulting compiled script can be attached to an Automator action. I don't know if you can attach a keyboard shortcut but you can add an Automator action to the Services menu and to the Finder's contextual menu.

  • How to execute unix command from the Java program running on Windows

    Hello,
    I need to
    1. Execute a unix shell script from a Java program running on the Windows.
    2. I also need to capture the output of this shell script in my program.
    Please suggest me how to achieve this.
    Thanks in Advance.

    Hi...
    Something is missing here
    If you want to execute a shell script in windows that not posible unless you find or develop a unix shell script parser for windows.
    But if you are trying the execute a unix shell script on a remote unix computer from your java program running on a windows platform you can do that by logging on to the UNIX terminal which is running on port 23 I think.
    You can test this using telnet tool on windows
    just type on command prompt
    telnet <ip of the unix pc> <port number this case 23>
    you should get the unix terminal. If that works you can do the same through java or you can directly conect to port 23 of that pc using sockets that way your program will be platform independant

    OdiOSCommand "-COMMAND=cd /project3/tmt/;ls *.dmp > dmplist.lst"

  • How can I import eex files into Applications EUL from the unix command line

    How can I import *.eex and *.dis files into an Applications EUL from the unix command line?
    Thanks

    Hi
    The simple answer is you either have to use the client tool DIS51ADM to import files using the command line (Discoverer Admin is a windows only client tool), or the Java command line which needs a browser.
    In theory if you have a browser running on your Unix box you may be able to use the Java command line to make this work.
