+### Creating a Shortcut to Execute a Terminal Command
+
+As an [example](https://forums.puri.sm/t/tutorial-create-a-shortcut-to-modem-info/16886), the following will create a shortcut to modem info,  similar to using Android's `*#*#INFO#*#*` service code.
+
+First, find an appropriate icon, edit it if desired, name it (e.g. modem.png), and save it to `.local/share/icons`, creating the `icons` folder if it doesn't exist already.
+
+Next, create the shortcut button in `.local/share/applications`, naming it e.g. `ModemInfo.desktop`. This will insert the icon/launcher into the home screen's app grid.
+
+In the terminal, enter `mmcli -L` to retrieve the modem's single-digit identifier. In this example, the command returns `/org/freedesktop/ModemManager1/Modem/0 [QUALCOMM INCORPORATED] 0`, which indicates "0" as the identifier. We can now run `mmcli --modem=0` to manually retrieve the detailed modem and mobile network information.
+
+Next, to enable the app screen launcher to run `mmcli --modem=0`, copy the following text into the `ModemInfo.desktop` file, which was created previously in `.local/share/applications`:
+
+[Desktop Entry]
+Name=ModemInfo
+Exec=gnome-terminal -x bash -c “mmcli --modem=0 | tee modeminfo.txt; exec bash”
+StartupNotify=true
+Terminal=false
+Type=Application
+Categories=Utilities;
+Icon=/home/purism/.local/share/icons/modem.png
+
+The above automates opening the terminal, running the command, and also saves the terminal output to a text file (`modeminfo.txt`) in the home folder, as well as setting the icon to use as the launcher, all from a single tap on the app icon. The text file will be overwritten every time.
+
+At this point, either view the output in the terminal opened by the launcher, or close the terminal and view the text file instead.
