srm:tldr:301bb
The command srm -m ${filename}
is used to securely delete a file from a system.
Here's a breakdown of each component of the command:
-
srm
: It is the command name and stands for "secure remove". It is typically used on Unix-like systems to securely delete files by overwriting their contents before removing them. The purpose is to prevent any possibility of recovering the deleted data. -
-m
: It is an option that specifies the method used for secure removal. The${filename}
is a placeholder for the actual file name that you want to delete.
Therefore, when you execute srm -m ${filename}
, the command will find the file specified by ${filename}
and overwrite its contents with random data multiple times before finally removing it from the system. This provides an increased level of security compared to a normal file deletion.
