Nemo

Nemo is a fork of GNOME Files (formerly known as Nautilus). It is also the default file manager of the Cinnamon desktop. Nemo is based on the Files 3.4 code. It was created as a response to the changes in Files 3.6 which saw features such as type ahead find and split pane view removed.

Installation

Extensions

Some programs can add extra functionality to Nemo. Here are a few packages that do just that:

• Nemo File Roller — File archiver extension for Nemo.

• Nemo Compare — An utility which compares two files using meld .

• Nemo Preview — GtkClutter and Javascript-based quick previewer for Nemo.

• Nemo Seahorse — PGP encryption and signing extension for Nemo.

• Nemo Share — Samba extension for Nemo.

• Nemo Terminal — Embedded terminal window for Nemo

• RabbitVCS Nemo — Integrate RabbitVCS into Nemo.

Configuration

Nemo is simple to configure graphically but not all options are in the preferences screen in Nemo. More options are available in the dconf-editor under org.nemo .

Set Nemo as default file browser

To set Nemo as the default file browser, execute the following:

$ xdg-mime default nemo.desktop inode/directory application/x-gnome-saved-search

Show / hide desktop icons

To enable/disable desktop icons rendering feature in nemo, change the following setting true or false (false to hide, true to show):

$ gsettings set org.nemo.desktop show-desktop-icons false

This fixes the console warning WARNING **: Can not determine workarea, guessing at layout for tiling window managers (such as i3).

Change the default terminal emulator for Nemo

gnome-terminal is set as the default, if it is not installed, neither the «Open in terminal» context menu entry feature will not work, nor shell scripts or terminal applications will not run from Nemo.

You can change the default setting with gsettings to the preferred terminal application.

$ gsettings set org.cinnamon.desktop.default-applications.terminal exec terminal-name 

To be able to run shell scripts from Nemo, make sure you set up the proper argument for the preferred terminal application (the default is -x for gnome-terminal ).

$ gsettings set org.cinnamon.desktop.default-applications.terminal exec-arg argument 

Set keyboard shortcut for «Open in terminal»

If you want to edit keyboard shortcuts, you need first to change /org/cinnamon/desktop/interface/can-change-accels respectively /org/gnome/desktop/interface/can-change-accels if you are using Gnome desktop. You can do that with dconf-editor or with this code in terminal:

$ gsettings set org.cinnamon.desktop.interface can-change-accels true

$ gsettings set org.gnome.desktop.interface can-change-accels true

Edit or create ~/.gnome2/accels/nemo and add the following line (replacing «F4» with the desired key combination):

(gtk_accel_path "/DirViewActions/OpenInTerminal" "F4")

, , and can be used as key modifiers (for example, t ).

Tips and tricks

Nemo Actions

Nemo allows the user to add new entries to the context menu. The file /usr/share/nemo/actions/sample.nemo_action contains an example of a Nemo action. Directories to place custom action files:

Action files must have the .nemo_action file extension.

Clam Scan

[Nemo Action] Name=Clam Scan Comment=Clam Scan Exec=gnome-terminal -x sh -c "clamscan -r %F | less" Icon-Name=bug-buddy Selection=Any Extensions=dir;exe;dll;zip;gz;7z;rar;

Moving files

[Nemo Action] Active=true Name=Archive %N Comment=Archiving %N will add .archive to the object. Exec= Selection=S Extensions=any;

#! /usr/bin/python2 -OOt import sys import os import shutil filename = sys.argv[0] print "Running " + filename print "With the following arguments:" for arg in sys.argv: if filename == arg: continue else: print arg #os.rename('%s','%s.archive') % (arg,arg) shutil.move(arg, arg+".archive")

Meld compare

compare-save-for-later.nemo_action

[Nemo Action] Active=true Name=Compare later Comment=Save file for comparison later. Exec= Icon-Name=meld Selection=S Extensions=any

compare-with-saved.nemo_action

[Nemo Action] Active=true Name=Compare with saved element Comment=Compare %F saved file or directory. Exec= Icon-Name=meld Selection=S Extensions=any

#!/bin/bash savedfile=/var/tmp/compare-save-for-later.$USER comparator=meld if [ "$1" == "save" ]; then shift echo "$*" > "$savedfile" elif [ "$1" == "compare" ]; then shift "$comparator" "$*" "$(cat $savedfile)" fi

Filenames containing spaces

By default, Nemo does not escape filenames. This means that actions for multiple files with some names containing spaces are broken. To fix this, use Quote=double .

Troubleshooting

Thumbnail generation errors shown in the console

By default, nemo does not generate thumbnails for certain video files due to licensing or patent problems (AVC encoded mp4 and mkv files for example). As such, you might see errors similar to the following in the console:

CinnamonDesktop-WARNING **: Error creating thumbnail for file:///home/username/video.mp4: Unrecognized image file format

for mp4 and other video files.

To fix this, ensure that you have a thumbnailer for video files installed—see File manager functionality#Thumbnail previews—and also ensure you have the necessary GStreamer packages installed that will allow the video file to be played.

Tip: Once thumbnail generation for video files is working, you can use nemo-preview to preview video files.

Desktop icons not shown

Since Nemo v3.4.2, the desktop is managed by nemo-desktop. This can be configured to auto start by copying the file /usr/share/applications/nemo-autostart.desktop to ~/.config/autostart/nemo-autostart.desktop and removing the line OnlyShowIn=X-Cinnamon; .

(GNOME) Opening a single file opens all files

Nemo was changed since v5.0.1 to allow the sort order to be maintained when passing multiple files to the image viewer. There is also a new GNOME setting to enable or disable it.

$ gsettings set org.nemo.preferences image-viewers-with-external-sort "[]"
