how can I safely unplug an usb device?

Hi,
coul you tell me how can I safely unplug an usb device?
I know that under windows there is a particular feature that you can run and after that you can safely unplud the usb device. Is there something similar under linux? (I'm using Fedora Core 3)
Thanks, Smau.

The safest way to use USB devices is to NOT use supermount (or similar), and rather mount it when it will be used, and unmount it after use. When unmounted, a USB device can safely be unplugged.

I wrote two simple bash scripts to mount and unmount a usb flash drive. Here is my mount script (called mount.sh)

Code:

#!/bin/bash

#Must be root to run this script

mount /mnt/usbstick

echo "mounted on /mnt/usbstick"

exit

Here is the simple script I use to un-mount my flash drive (called umount.sh)

Code:

#!/bin/bash

#unmounting a usb thumb drive, must be root

umount /mnt/usbstick

echo "unmounted."

exit

To run those scripts just copy and paste the script and save it as a .sh file. Once you have it saved don't forget to make it executable (chmod +x). Then you can run the script with ./(name of script) assuming the script is in your present directory.

Here is my fstab entry for /mnt/usbstick:

Code:

/dev/sda1 /mnt/usbstick vfat user,noauto,umask=0 0 0

How can I make it executable (chmod +x) ? What is the fstab entry?
I am newbie, please explain...

/etc/fstab lists the devices to be mounted at boot time, where to mount them, the file system to be used, and other various parameters.

/etc/mtab provides the output of what was ACTUALLY mounted at boot.
