# Description:
# This script helps to mount a CIFS network share on Ubuntu/Mint/Debian OS

# Attempt to mount a network share using cifs protocol.
# Takes a server share address and target mount point as input, and writes the values to /etc/fstab

# Update the .smbcredentials file with CIFS username and password
# Template for .smbcredentials:
#   username=<cifsusername>
#   password=<password>

# Variables here
# cifs host1: //smb_server_name/share_name
# Please replace smb_server_name and share_name with your server name and share name respectively.

cifs_host="//smb_server_name/share_name"

# cifs host mountPoint1: mount_point_name
# Replace mount_point_name with the name where you want your network share to be mounted.

mount_point="/mnt/mount_point_name"

# Ask user to update .smbcredentials file with their respective CIFS username and password
echo "Editing .smbcredentials file, please enter your credentials (CIFS username and password)."
sudo nano /root/.smbcredentials

# Create a Mount point Directory using variable mount_point
if [ ! -d $mount_point ]; then
    sudo mkdir -p $mount_point
fi

# Change permissions to root only access for .smbcredentials as it has sensitive data
sudo chmod 700 /root/.smbcredentials

# Install cifs-utils if not installed
sudo apt-get install cifs-utils -y

# Add the CIFS entry to /etc/fstab
echo '# CIFS mount for network share' | sudo tee --append /etc/fstab > /dev/null
echo "${cifs_host} ${mount_point} cifs credentials=/root/.smbcredentials,iocharset=utf8,_netdev,file_mode=0777,dir_mode=0777 0 0" | sudo tee --append /etc/fstab > /dev/null

# Mount all filesystems mentioned in /etc/fstab
echo "Mounting all filesystems..."
sudo mount -a
# Display all mounted filesystems with their sizes
echo "Displaying details of all mounted filesystems..."
df -h
