To securely delete all files in Linux AWS, you can use the shred command. Shred overwrites the file contents multiple times, making it difficult to recover the data.
To delete all files in a directory, you can use the following command:
find /path/to/directory -type f -exec shred -uvz {} +
This command finds all files in the directory, and securely deletes them one by one. The -u option is used to truncate the file after deletion, the -v option provides verbose output, and the -z option fills the file with zeros before deletion.
