I am writing a script that automatically copies sqlite files from my computer to a USB stick whenever the stick is inserted. It makes a new directory on the USB that takes the hostname of the computer, as I will be downloading from multiple computers.

The script is as follows:

#!/bin/bash
# Set the source folder to download from
src_dir="/home/atlas/atlas/runs/server"

Define hostname


usb_hostname=$(cat /etc/hostname)


Find USB path


usb_path=$(find /media/atlas/*/ -maxdepth 0 -type d -print -quit)
echo "USB path = $usb_path"


Set the destination


dest_dir=$usb_path$usb_hostname


Mount the USB device


sudo mount -t vfat /dev/sd?1 dest_dir


Create a directory on the USB stick


sudo mkdir -p $dest_dir


Copy the files with 'sqlite' in the extension from the source folder to the destination folder


find $src_dir -type f -iname "sqlite" -exec cp {} $dest_dir ;


Unmount the USB device


sudo umount dest_dir

The script works perfectly when I run it in terminal, however when it runs on insertion it fails on the 'find' command (line 'usb_path ='), where it returns 'No such file or directory'.

Things I have tried:

  • Setting 'sleep 5' at the start of the script to allow time to mount; I've extended the time of this too with no change
  • Checking permissions for the script to access the /media/atlas/ directory
  • There are no errors in the syslog file
  • 'atlas' is my user; if I change this to $(whoami) the script changes the path to /media/root/ and also cannot find any directory
  • The USB device is mounted correctly (as I said, the script works fine from terminal)
  • I've checked and the script does recognise /media/atlas, it just doesn't recognise any sub-directories

I'm at my wits end here. I can see that the problem is that when automatically run, the shell script can't find any directories within /media/atlas/ but I have no idea why. Any suggestions would be very much appreciated.
