Hello donya, welcome to LQ,

could you please provide more information about what you want to do?

What has the USB-device to do with your program? if you want to find out more about the USB-devices on your system you may use the commands "dmesg", "lsusb" or read about udev, the manpages are available with the commands

Code:

man dmesg

and

Code:

man lsusb

and

Code:

man udev

Hello Markush
Thank you for replay my question .

I want to write a program with eclips Software .
This program should be identity usb flash that coneccted to PC, then
write or read files in/from it .

thanks

Well, normally the USB-device is mounted automatically, you'll only have to parse the output of

Code:

df

to find out where the device is mounted.

how to do use "Code : df " ?

markush · 08-17-2011, 12:57 AM

I'll give you an example with Perl:

Code:

#!/usr/bin/perl

use strict;
use warnings;

my $line;
foreach $line (`df`) {
    if ($line =~ m/(\/media\/.+)/) {
        my $path = $1;
        print $path, "\n";
    }
}

provided that all USB-devices are automatically mounted anywhere in /media this program will show you the full path of any device which on your system is mounted in /media.

Hope that helps

And I should be Work with C on Eclips

donya · 08-17-2011, 01:23 AM

Markus can you please give me a sample with C ?

markush · 08-17-2011, 03:24 AM

No, I'm not a programmer and my knowledge of C is not sufficient for this.

I'd recommend that you use the "Report" Button at one of your posts and ask a Moderator to move this thread to "Programming" http://www.linuxquestions.org/questions/programming-9/

Moved: This thread is more suitable in <PROGRAMMING> and has been moved accordingly to help your thread/question get the exposure it deserves.

Do you just want to copy files to the device after it has been mounted? If so, why are you using C instead of a shell script, for example?

Is this the Eclipse that you are talking about? Or is it one of the other ones found here? Since you did not supply a link or give other identifying info., we need clarification.

Is this homework or some other kind of project where using Eclipse is one of the conditions? Please say so, otherwise we will waste time suggesting simpler ways to do the job.
