To securely delete all files on a Linux system hosted on Amazon Web Services (AWS) so that they cannot be recovered, you can use the shred
command. shred
is a utility that overwrites the data in a file multiple times, making it difficult or impossible to recover the original data.
To use shred
, you will need to install it on your system. On most Linux systems, shred
is included in the coreutils
package, which can be installed using the package manager. For example, on a Debian or Ubuntu system, you can use the apt-get
command to install shred
:
sudo apt-get install coreutils
On a CentOS or Red Hat system, you can use the yum
command to install shred
:
sudo yum install coreutils
Once shred
is installed, you can use it to securely delete all files in a directory by running the following command:
find /path/to/directory -type f -exec shred -u -z {} +
This will find all files in the /path/to/directory
directory, and overwrite the data in each file multiple times using the shred
command. The -u
option specifies that the file should be deleted after it has been overwritten, and the -z
option specifies that the final pass should be filled with zeros.
Note that this process can take some time, depending on the number and size of the files being deleted.
For more information about using shred
to securely delete files on a Linux system, you can consult the shred
documentation or seek assistance from a qualified Linux administrator.
