Ubuntu – Bash script doesn’t run from nautilus, but does run from terminal

bashnautilusscriptsshared library

Before I add more detail to my question, I have to say something very important:

Yes, my script has "Allow executing file as program" turned on.

The question itself:

For programming reasons (shared libraries), I can't execute my program just from the executable, because I need to access LD_LIBRARY_PATH before executing the program. I created this script to do this (baring in mind this is my first time ever writing a script):

#!/bin/bash
#Get the current directory and append the SO's location
currentDir=$(pwd)'/libs/'

#Change the library path
export LD_LIBRARY_PATH=$currentDir

#Run the program
./program

After running this from the terminal I thought that it has worked, there were no errors and the program didn't complain about shared libraries. But unfortunately, if I try to double-click the .sh file from Nautilus, nothing happens. The worst part as well, is that since I'm running it from the GUI, I have no idea what error it is getting. I'm running Ubuntu 14.04 and the executable is a C++ program using the SFML libraries (Yes I could just have the dependencies, but SFML isn't commonly installed on Linux computers, and this is besides the point).

The property Allow executing file as program is not enough.

Change the settings in Nautilus Preferences

or via terminal:

gsettings set org.gnome.nautilus.preferences executable-text-activation ask

First of all, you can use

sudo apt-get install pkg1 pkg2 ... pkg3

and next, with the option -y, apt-get will not ask for confirmation.

Ubuntu – How to run commands from a bash file the way they run from terminal

Consider this script (saved as /home/muru/test.sh):

#! /bin/bash
DRI_PRIME=1 glxgears -info

A basic launcher for this would look like (say, save it as /home/muru/test.desktop):

[Desktop Entry]
Type=Application
Terminal=true
Name=glx-gears-info
Exec=/home/muru/test.sh

Make them both executable:

chmod +x test.sh test.desktop

Now you should have these two entries in your home folder: enter image description here

Notice how the name is glx-gears-info even though the launcher's filename is test.desktop. You can double click on it to start the script: enter image description here

For a script like (say, located at /home/muru/start-aria.sh):

#!/bin/bash
touch /home/cip/Downloads/aria2/session.txt && \
    aria2c --enable-rpc --rpc-listen-all \
       --save-session=/home/cip/Downloads/aria2/session.txt \
       --input-file=/home/cip/Downloads/aria2/session.txt -x16 -s16 -k1M \
       --dir=/home/cip/Downloads/aria2

(I split the command into multiple lines for readability) the launcher file would look like (say /home/muru/start-aria.desktop):

[Desktop Entry]
Type=Application
Terminal=false
Name=Start Aria2
Exec=/home/muru/start-aria.sh

You can set Terminal=false here as this command probably doesn't need a terminal.

To get the terminal window when using Xfce launchers, tick 'Run in Terminal'.

enter image description here

A second command, that would close aria2, can be added in the same Xfce launcher: pkill aria2c

Also:

by adding them into a single launcher,
setting advanced properties like in the image below

enter image description here

(namely 'show last used item' and 'inside button'),

and adding two specific icons,

the launcher will always display the current status of aria2: running or closed.
