Simple network folder mount script for Linux

I wrote a simple little network mount script for Linux desktops. I wanted to replicate my Windows box as best as I could where a bunch of network drives are mapped upon user login. This script relies on having gvfs-mount and the cifs utilities installed (installed by default in Ubuntu.)

#!/bin/bash
#Simple script to mount network drives

#Specify network paths here, one per line
#use forward slash instead of backslash
FOLDER=(
  server1/folder1
  server1/folder2
  server2/folder2/folder3
  server3/
)

#Create a symlink to gvfs mounts in home directory
ln -s $XDG_RUNTIME_DIR/gvfs ~/Drive_Mounts

for mountpoint in "${FOLDER[@]}"
do
  gvfs-mount smb://$mountpoint
done

Mark this script as executable and place it in /usr/local/bin. Then make it a default startup application for all users:

vim /etc/xdg/autostart/drive-mount.desktop
[Desktop Entry]
Name=Mount Network Drives
Type=Application
Exec=/usr/local/bin/drive-mount.sh
Terminal=false

Voila, now you’ve got your samba mount script starting up for every user.

Using screen to run interactive programs at startup

Oftentimes I will encounter programs that weren’t necessarily designed to be automatically run that I want to run on startup. Sometimes that program will have interactive information that you will want to see later, but you still want it to run on startup.

The solution to this particular problem is using screen in combination with su and bash. In my situation, I want to run the HDSurfer plugin on bootup as a different user. The solution I came up is as follows (thanks to superuser.com and stackoverflow.com for the guidance I needed to set this up.)

Install screen

Screen is like having a separate X window session to keep a program running, except it is for console programs. You can attach and detach to this screen whenever you’d like and not worry about the program terminating.

sudo apt-get install screen

Create a script to run your program with all required arguments

In my case I needed to execute the command “python /usr/bin/HDSurferWave/hdsurferwave.py start” as a different user in a screen session (so it wouldn’t terminate when the terminal session did.) To do this,

  • invoke screen with the -dm command (to begin the program in detached mode)
  • issue the bash -c argument afterward to invoke bash
  • Include your desired command after that

My one line script looks like this:

screen -dm bash -c "python /usr/bin/HDSurferWave/hdsurferwave.py start"

Run your script

I use the su command with the -c argument to change the user that will be running the script, as the startup script launches things as root by default (with pre-systemd systems, anyway.) The -s command initiates a shell to launch, and the last argument is the user you want to run as. My launch argument is:

su -c "/usr/bin/HDSurferWave/start.sh" -s /bin/sh nicholas

Configure the script to run on startup

Edit /etc/rc.local and add your script command from above, then mark that file as executable by running chmod +x /etc/rc.local. Note: This will not work with systems using systemd.
