.B mat2
|
2019-03-26 18:10:46 +01:00
|
|
|
removes metadata from various fileformats. It supports a wide variety of file
|
2018-07-24 22:34:33 +02:00
|
|
|
formats, audio, office, images, …
|
|
|
|
|
|
2018-09-26 00:13:44 +02:00
|
|
|
Careful, mat2 does not clean files in-place, instead, it will produce a file with the word
|
|
|
|
|
"cleaned" between the filename and its extension, for example "filename.cleaned.png"
|
|
|
|
|
for a file named "filename.png".

.SH NOTES ABOUT METADATA
|
|
|
|
|
|
|
|
|
|
While mat2 is doing its very best to display metadata when the --show flag is
|
|
|
|
|
passed, it doesn't mean that a file is clean from any metadata if mat2 doesn't
|
|
|
|
|
show any. There is no reliable way to detect every single possible metadata for
|
|
|
|
|
complex file formats.
|
|
|
|
|
.PP
|
|
|
|
|
This is why you shouldn't rely on metadata's presence to decide if your file must
|
|
|
|
|
be cleaned or not.

.SH BUGS
|
|
|
|
|
|
|
|
|
|
While mat2 does its very best to remove every single metadata,
|
|
|
|
|
it's still in beta, and \fBsome\fR might remain. Should you encounter
|
|
|
|
|
some issues, check the bugtracker: https://0xacab.org/jvoisin/mat2/issues
