Bash script to detect when my USB is plugged in and to then sync it with a Directory

问题

Is there a Bash script and/or daemon that I can write that will detect a specific USB drive and then sync that drive with a directory?

回答1:

For future reference, here's how to run a bash script upon detection of a USB drive.

Connect your device and run lsusb to retrieve the device's info. You should see something similar to this:

$ lsusb
Bus 002 Device 039: ID 0bc2:2100 Seagate RSS LLC

In this case, the vendor ID of the device is 0bc2 and the product ID is 2100.

Now you can create your UDEV rule using a text editor of your choice.

$sudo vi /etc/udev/rules.d/85-my_usb_device_rule.rules

And add this:

ACTION=="add", SUBSYSTEM=="usb", SYSFS{idVendor}=="0bc2", SYSFS{idProduct}=="2100", RUN+="/home/myhome/my_script"

/home/myhome/my_script is the path to your script which it would do whatever you want.

To make sure the detection script will execute right away, run this command to reload the UDEV rules:

$sudo udevadm control --reload-rules

This was tested on Fedora 14.

I didn't do it myself, but you can try udev rules like this:

# Hitachi SimpleDrive mini, model HTS545050B9A300 (500 GB USB HDD)
SUBSYSTEM=="block", ATTR{size}=="976768002", ATTRS{product}=="SimpleDrive mini", ATTRS{serial}=="2512009121920487", ACTION=="add", RUN+="/lib/udev/local.usb.hdd.sh add $devpath"

Place it in /etc/udev/rules.d/90-local.rules or similar place, certainly dependable on your OS.

Here is an example python deamon that you could use for the listening part, then copying the files to your directory shouldn't be a problem.
