This is related with Execute sh script from *.desktop file? but here the OP asks how to call a bash script from an icon.
I want to write a shell script that is called from an icon and return the name of a file (in this case a .xlsx). In a webserver I would just return the correct mime type but I have no idea of what I need to do in the GNOME context.
My script would be something like
#!/bin/bash
X=$(ls -tr /mydatadir/myfile-* | tail -1)
echo $X
Thanks in advance.
This works, but not in the way I want. Here I'm calling the program that handles myfile directly from the script. I want the script to find out the name, return it to Gnome and let Gnome handle it. It's like when you have a script on a webserver when you return the mime type for something like a GIF and then return the data, and the browser knows how to make that look like a picture. It must (I think) be possible to do something like that with the Gnome desktop.
file: ~/Desktop/myfile.desktop
[Desktop Entry]
Name=Last Myfile

X=$(ls -tr $DIR | tail -1)
nohup /usr/lib64/libreoffice/program/oosplash --calc file://$DIR/$X &
