On Linux or UNIX OS, you can mount a Windows share on a specific point in the local directory tree using mount command with the cifs option. The Common Internet File System (CIFS) is a network file-sharing protocol. CIFS is a form of SMB. This tutorial explains how to mount Windows share on Linux systems.
Install CIFS Packages
You need to install the CIFS utilities package to mount a Windows share on a Linux systems.
Install CIFS utilities on Ubuntu and Debian:
sudo apt update
sudo apt install cifs-utils
Installing CIFS utilities on CentOS and Fedora:
sudo dnf install cifs-utils
For different Linux distributions, the package name might be differ.
Mount a CIFS Windows Share
It is a simple to mount the remote Windows share.
First of all, you should create a directory to serve as the mount point for the remote Windows share:
sudo mkdir /mnt/Windows_Share
After that, run the below command to mount the share as root or user with sudo privileges:
sudo mount -t cifs -o username= //WIN_SHARE_IP/ /mnt/WIN_SHARE
It will ask to enter the password:
Password:
On success authentication, it will not show any output.
You can verify using the mount or df -h command that Windows share is mounted properly.
Auto Mounting
If you mounted share manually using mount command, it will not persist after a reboot. The /etc/fstab file contains a list of entries that define where how and what filesystem will be mounted on system startup.
You should define the mount in the /etc/fstab file to mount a Windows share automatically on your Linux system start up. The line must include the hostname or the IP address of the Windows PC, the share name, and the mount point on the local machine
Edit the /etc/fstab file with your text editor :
sudo nano /etc/fstab
Now add the following line to it:
# <file system> <dir> <type> <options> <dump> <pass>
//WIN_SHARE_IP/SHARE_NAME /mnt/WIN_SHARE cifs credentials=/etc/win-credentials,file_mode=0755,dir_mode=0755 0 0Run the following command to mount the share:
sudo mount /mnt/WIN_SHARE
The mount command, will read the content of the /etc/fstab and mount the share.
Now once you reboot the system, the Windows share will be mounted automatically.
Unmounting Windows Share
You can detaches the mounted file system from the directory tree using the umount command:
sudo umount /mnt/WIN_SHARE
Check the fstab file that if the CIFS mount has an entry and remove it.
Make sure the umount command will failed to detach when the share is in use. Use the fuser command to find out which processes are accessing the windows share:
fuser -m MOUNT_POINT
After finding the processes, you can stop those using the kill command and umount the share.
Even if the umount failed, you can use the -l (--lazy) option to umount busy file system:
sudo umount -l MOUNT_POINT

This guide shows you how to mount a Windows shared using the mount command with the cifs option.
