Given a file path, unplug the USB device on which the file is located (the file must be on an USB device !)

You have an external USB drive or key.

Apply this command (using the file path of anything on your device) and it will simulate the unplug of this device.

If you just want the port, just type :

echo $(sudo lshw -businfo | grep -B 1 -m 1 $(df "/path/to/file" | tail -1 | awk '{print $1}' | cut -c 6-8) | head -n 1 | awk '{print $1}' | cut -c 5- | tr ":" "-")

Nice one, tweet78 !. Works for my USB key and my external HDD.

I have I/O errors while writing on my usb drive.

Thanks to your command, I wrote a script to unplug / replug and resume transfer. Very useful, thanks !

Interesting, but will not work if the file is on a raid 1 array for example (several devices) ...

Comment by stevebaker 67 weeks and 3 days ago

not bad, but I'm sure I could write a shorter command, still working on it !

Comment by nullpointer 67 weeks and 3 days ago

Comment by zaius 65 weeks and 6 days ago

works well for me on Fedora 20, but, as stated, should be improved to manage raid
