srm - securely wipe files
|
||||
--------------------------
|
||||
srm is a utility to overwrite files with random data in one or more passes.
|
||||
|
||||

||||
------------
|
||||
None.
|
||||
|
||||
|

|
||||
* Linux (Debian 6.0)
|
||||
|
||||
|
||||
Installation
|
||||
------------
|
||||
make build install
|
||||
|
||||
|
||||
Usage
|
||||
-----
|
||||
srm [-v] [-n number] file list
|
||||
|
||||
options:
|
||||
-n <number of passes>: specify number of passes
|
||||
(default is 3 passes)

|
||||
.Sh DESCRIPTION
|
||||
.Nm
|
||||
is a simple secure file deletion tool. It overwrites the file with several
|
||||
passes of random data before unlinking it. If no options are specified, Nm
|
||||
defaults to three passes.
|
||||
.Nm
|
||||
supports the following options:
|
||||
.Bl -tag -width .Ds
|
||||
.It Fl h
|
||||
Display a brief help message.
|
||||
.It Fl n Ar number
|
||||
Specify the number of times to overwrite each target with random data.
|
||||
.It Fl r
|
||||
Recursive mode. Delete any directories and all subdirectories underneath.
|
||||
.It Fl v
|
||||
Verbose mode. Displays a list of both files that failed to wipe and files that
|
||||
were successfully wiped.
|
||||
.It Fl V
|
||||
Print version information.
|

.El

.Sh EXIT STATUS
|
||||
.Ex -std
|
||||
The exit values are standard
|
||||
.Xr sysexits 3
|
||||
values.
|
||||
.Sh EXAMPLES
|
||||
Wipe files
|
||||
.Pa foo
|
||||
and
|
||||
.Pa bar
|
||||
with three passes:
|
||||
.Dl $ srm foo bar
|
||||
Wipe files
|
||||
.Pa baz
|
||||
and
|
||||
.Pa quux
|
||||
with ten passes:
|
||||
.Dl $ srm -n 10 baz quux
|
||||
Wipe all PGP keys, i.e. files with extension
|
||||
.Pa *.asc :
|
||||
.Dl $ srm *.asc
|
||||
Recursive deletes aren't implemented yet. A workaround is to use
|
||||
.Nm
|
||||
and
|
||||
.Xr find 1 ,
|
||||
for example to delete all
|
||||
.Pa *.pgp
|
||||
files:
|
||||
.Dl $ find . -iname '*.pgp' -exec srm '{}' \;
|
||||
.Sh DIAGNOSTICS
|
||||
.Nm
|
||||
uses the standard
|
||||
.Xr err 3
|
||||
facilities to report any errors that occur.
|
||||
