srm is a secure replacement for rm(1). Unlike the standard rm, it overwrites
|
||
|
|
the data in the target files before unlinking them. This prevents command-line
|
||
|
|
recovery of the data by examining the raw block device. It may also help
|
||
|
|
frustrate physical examination of the disk, although it's unlikely that it can
|
||
|
|
completely prevent that type of recovery. It is, essentially, a paper shredder
|
||
|
|
for sensitive files.
|
||
|
|
|
||
|
|
srm is ideal for personal computers or workstations with Internet connections.
|
||
|
|
It can help prevent malicious users from breaking in and undeleting personal
|
||
|
|
files, such as old emails. It's also useful for permanently removing files
|
||
|
|
from expensive media. For example, cleaning your diary off the zip disk you're
|
||
|
|
using to send vacation pictures to Uncle Lou. Because it uses the exact same
|
||
|
|
options as rm(1), srm is simple to use. Just subsitute it for rm whenever you
|
||
|
|
want to destroy files, rather than just unlinking them.
