How To Install FreeFileSync in Ubuntu Linux
We will add official FreeFileSync PPA, which is available for Ubuntu 14.04 and Ubuntu 15.10 only, then update the system repository list and install it like so:
-------------- On Ubuntu 14.04 and 15.10 -------------- $ sudo apt-add-repository ppa:freefilesync/ffs $ sudo apt-get update $ sudo apt-get install freefilesync
On Ubuntu 16.04 and newer version, go to the FreeFileSync download page and get the appropriate package file for Ubuntu and Debian Linux.
Next, move into the Download folder, extract the FreeFileSync_*.tar.gz into the /opt directory as follows:
$ cd Downloads/ $ sudo tar xvf FreeFileSync_*.tar.gz -C /opt/ $ cd /opt/ $ ls $ sudo unzip FreeFileSync/Resources.zip -d /opt/FreeFileSync/Resources/
Now we will create an application launcher (.desktop file) using Gnome Panel. To view examples of
.desktop files on your system, list the contents of the directory /usr/share/applications:
$ ls /usr/share/applications
In case you do not have Gnome Panel installed, type the command below to install it:
$ sudo apt-get install --no-install-recommends gnome-panel
Next, run the command below to create the application launcher:
$ sudo gnome-desktop-item-edit /usr/share/applications/ --create-new
And define the values below:
Type: Application Name: FreeFileSync Command: /opt/FreeFileSync/FreeFileSync Comment: Folder Comparison and Synchronization
To add an icon for the launcher, simply clicking on the spring icon to select it: /opt/FreeFileSync/Resources/FreeFileSync.png.
When you have set all the above, click OK create it.
If you don’t want to create desktop launcher, you can start FreeFileSync from the directory itself.
