Como o mouse clica com o botão direito do mouse para calcular a soma MD5 de um arquivo?
How does one mouse right-click action to compute the MD5 sum of a file?
You can work with a nautilus script.
Create the scripts directory if it does not yet exist
mkdir -p ~/.local/share/nautilus/scripts/
Place your script into that directory and make it executable (
chmod +x <name_of_script> or via your file manager: right-click file, properties). Any executable script you put there will be available under an entry "Scripts" in your right-click menu.
In your script, you can use the variable
NAUTILUS_SCRIPT_SELECTED_FILE_PATHS to retrieve a newline-delimited list of selected files (i. e., one file path in case you selected a single file). You will also need to display the output: this can be done by piping the output of the command to zenity. This simple script will already cut it:
#!/bin/bash set -eu -o pipefail md5sum "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS" | zenity --text-info
