    copy command

    hi all
    sorry for this query.. it is a unix question.. i am hoping that i can get solution from this good forum.
    how can i copy largefiles too (1Mb to 10Gb)
    i tried using this command "cp -r xxxxx-1.1.1.tar.gz" to some path , this path i am giving
    i did this all by programatically..
    but this program copying only small files like .xpm, .png, .txt, .c etc...
    when i am sending xxxxx-1.1.1.tar.gz of 1.2Mb size it saying like this and also not copying
    cp: cannot stat `xxxxx-1.1.1.tar.gz': No such file or directory
    how can i copy this type of large file tooo?

    can you please help me

    You could if you asked in Linux or Tech...

    Sure the file exists? -r is recursive, do a man cp

    Post some actual code, like how you read the filename(s), open the files etc etc.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    i doing like this in gtk c.
    Code:
    char *s1;
    s1=g_strconcat("cp -i ",split1_filename11[1]," ", file,NULL);
       FILE* F;
       F=popen(s1,"r");
       pclose (F);
    "gchar **split1_filename11[1]" (file name)is a global declaration , it is getting from server.
    "file" is where to save.

    i used rcp also
    Code:
    char *s1;
    s1=g_strconcat("rcp -p ",split1_filename11[1]," ", file,NULL);
    all it saying
    cp: cannot stat `xxxxx-1.1.1.tar.gz': No such file or directory
    at file receiving side(at other machine)

    can you help me
    thank you in advance

    how do you assign gchar **split1_filename11[1]?

    g_strconcat returns gchar *.

    The file size has nothing to do with being able to find it (or not).
    Since you seem to be using a remote machine, check what it considers to be the current directory.

    the file size is ok..
    gchar **split1_filename11;
    let me clear my doubt.

    first am clicking send button, it will open file chooser..
    file choosing starts from working directory.
    i think here causing the problem.
    if i send a file from working directory , sucessfully sent to other machine. by using "cp -i" or "rcp -p".
    if i send a file from otherthan working directory..
    it showing the message and not sending my file to other machine.

    cp: cannot stat `filename': No such file or directory

    how can i do this..
    please help me

    thank you in advance

    Well I guess your file chooser has some way of telling you which directory it was in when you picked the file.

    This isn't a C problem, it's simply a matter of RTFM to find out how the API you're using really works.

    yes am choosing the file when send button clicked in my machine ...to send.
    and choosing the file save button clicked in other machine..to save.
    i am running this exe. from source code path is
    /root/Desktop/123/src/run(run is my exe name)
    /root/Desktop/123/src/one.png this is the sending file..(one.png is the sending file)
    and at the receiving side /root/Desktop/6666... this is the saving path(6666 is the folder wr to save)
    like this it is sucessfully sending and receiving.

    and
    root/Desktop/two.png this is the sending file..(two.png is the sending file)
    and at the receiving side /root/Desktop/6666... this is the saving path(6666 is the folder wr to save)
    it is sending file but not receiving at the other machine...
    saying the same error.

    i think this is the only problem with file chooser..

    can you suggest me

    thank you in advance
