Mount samba share as user

Utility to mount samba share as user

The Linux mount utility does not allow for a user to mount a samba share on Arch based systems.

This script relies on the packages gvfs-smb which will pull the necessary smb-client dependency. The following command will do the trick. If you want the dependencies to be explicitly installed add gvfs and smbclient to the command. The --needed argument will skip syncing packages already present.


sudo pacman -Syu gvfs-smb --needed

Create a new script in ~/.local/bin and name it gio-mount-myshare.sh.


mkdir -p ~/.local/bin
touch ~/.local/bin/gio-mount-myshare.sh

Paste below content and modify the variables to use your samba server and share name.

The symlinks folder defaults to ~/SMBLinks and this can of course be changed as you see fit.

Running the script will attempt mounting the share. If credentials are needed you will be challenged. Enter the correct credentials to continue. To unmount a mounted share run with -u argument


#! /bin/bash
#
# Script for mounting and unmounting a configured samba share
#  Customized the variables as needed
#  - Symlinks are located in designated folder (default: $HOME/SMBLinks)
#  - Symlink can be named  (default: $SHARENAME)
#  - Using `-u` argument will unmount and remove the symlink

The script can be utilized in a systemd user service

cat /home/$USER/.config/systemd/user/gio-mount-share.sh


[Unit]
Description=GIO mount smb share-name

[Service]
Type=oneshot
ExecStart=/home/%u/.config/systemd/user/gio-mount-share.sh
ExecStop=/home/%u/.config/systemd/user/gio-mount-share.sh -u
RemainAfterExit=true

[Install]
WantedBy=multi-user.target

check connection


checkConnection(){
    # use nmap to check the host for smb service
    if [ -z  $(nmap $HOST -PN -p 445 | grep open | cut -d' ' -f2) ] ; then
        echo "$HOST"
    fi
}
