Use this command to securely delete a file in #linux

The “shred” command is a command-line utility in Linux operating systems. It is used to securely delete a file or a directory by overwriting the data with random characters multiple times, making it nearly impossible to recover the original data. This is useful when you want to ensure that sensitive information is not recoverable after deletion.

The basic syntax of the shred command is:

shred [options] file

Here’s an example of how the shred command can be used

shred -n 5 -vzu secret.txt

The “v” option us used to display verbose output

The “z” option is used to add a final overwrite with zeroes to the file before deletion. This is an extra step that makes it even more difficult to recover the original data.

The “u” option means that once the “shred” command has finished running, the file will no longer exist on your system.

The “n” option is used with the “shred” command to specify the number of times the data should be overwritten.

Type shred with help option to view all shred command options.
