I need a bash script to check connected/disconnected usb with linux.
I know command lsusb can be use to list down usb connect with linux. output of lsusb command is like this:
Code:
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 0951:1643 Kingston Technology DataTraveler G3 4GB
Bus 001 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
Device 002 is only usb in above text. Now I want to get Size of USB and Name of USB and output it in some file. but size can be different. in gb or in mb or in tb.
thanks in advance.
Also do tell me if there is some other way to handle this issue.

I'd like to make a wrapper bash script that will make sure that an nfs mount is mounted before launching a program that depends on the mount being active. Basically:
1) Check to see if the mount is active
2) If it's not active, try to mount it
3) If it won't mount because the nfs server is... (3 Replies)

Is there an easy way to setup a cross-over cable (USB-USB) between a linux box and a windows PC? My 2 machines are next to each other but I really do not want to keep transfering my files using my USB drive.

Hey guys, so I wrote a small script that pretty much just takes in two numbers and counts from the first to the second, e.g.

My problem is I want to make it so that if you input invalid parameters, such as non-numerical characters, more than 2... (2 Replies)
I'm a bit new to bash programming and I was assigned the job of writing a script that will check to see if a program server is running and to restart the program if it is not up. The script is supposed to check the program every hour (which I have looked up and I believe I know how to do) and send... (3 Replies)

usb-devices(1) Linux USB Utilities usb-devices(1)NAME
usb-devices - print USB device details
SYNOPSIS
usb-devices
DESCRIPTION
usb-devices is a (bash) shell script that can be used to display details of USB buses in the system and the devices connected to them.
The output of the script is similar to the usb/devices file available either under /proc/bus (if usbfs is mounted), or under /sys/ker-
nel/debug (if debugfs is mounted there). The script is primarily intended to be used if the file is not available.
In contrast to the usb/devices file, this script only lists active interfaces (those marked with a "*" in the usb/devices file) and their
endpoints.
Be advised that there can be differences in the way information is sorted, as well as in the format of the output.
RETURN VALUE
If sysfs is not mounted, a non-zero exit code is returned.
FILES
/sys/bus/usb/devices/usb*
The part of the sysfs tree the script walks through to assemble the printed information.
/proc/bus/usb/devices
Location where the usb/devices file can normally be found for Linux kernels before 2.6.31, if usbfs is mounted.
/sys/kernel/debug/usb/devices
Location where the usb/devices file can normally be found for Linux kernel 2.6.31 and later, if debugfs is mounted.
