From 175fb1e562f55cb6e92a528b1b6be98b5f45dbd8 Mon Sep 17 00:00:00 2001 From: Thomas Schmitt Date: Tue, 7 Jul 2020 13:40:54 +0000 Subject: [PATCH] --- Xorriso.md | 60 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 60 insertions(+) create mode 100644 Xorriso.md diff --git a/Xorriso.md b/Xorriso.md new file mode 100644 index 0000000..d603b49 --- /dev/null +++ b/Xorriso.md @@ -0,0 +1,60 @@ +xorriso is a command line and dialog application, which creates, loads, +manipulates and writes ISO 9660 filesystem images with Rock Ridge extensions. +It is part of the [libisoburn](Libisoburn) release tarball. + +It copies file objects from POSIX compliant +filesystems into Rock Ridge enhanced ISO 9660 filesystems and performs +session-wise manipulation of such filesystems. It can load the management +information of existing ISO images and it writes the session results to +optical media or to filesystem objects. If linked with `zlib` then it is able +to produce the [zisofs compression format](zisofs). Directory tree, +whole session, and single data files may be equipped with MD5 checksums. + +Vice versa xorriso is able to copy file objects from ISO 9660 filesystems +to the disk filesystem. At that occasion it can restore ACLs and user xattr +which it may have recorded when creating the filesystem. +It can also decode `zisofs` +compression. MD5 checksums may be used to detect any data corruption. +To avoid unpleasant user surprises, the ISO-to-disk feature has first to be +enabled by option -osirrox. + +By its `-as mkisofs` emulation, xorriso is serving several GNU/Linux +distributions for the production of bootable ISO images, which not only +boot from CD, DVD, and BD, but also from disk-like devices like USB pen drives. +For an overview of known and supported boot sectors see +[page about command -report_system_area](Reportsystemarea). + +A special property of xorriso is that it needs neither an external ISO 9660 +formatter program nor an external burn program for CD, DVD, or BD but rather +uses the libraries of libburnia-project.org . Especially it is +related to [libisoburn](Libisoburn) which hosts source and object code +of xorriso. The dynamically linked binary of xorriso is therefore very lean. + +All xorriso features may be used by other programs via a C language API +[libisoburn/xorriso.h](https://dev.lovelyhq.com/libburnia/libisoburn/raw/HEAD/xorriso/xorriso.h). + +Another approach for frontends via a pair of pipes and xorriso dialog mode +is demonstrated by +[xorriso-tcltk](https://dev.lovelyhq.com/libburnia/libisoburn/raw/HEAD/frontend/README-tcltk) +See this [screenshot of xorriso-tcltk](http://www.gnu.org/software/xorriso/xorriso-tcltk-screen.gif). + +----------------- + +Have a look at the +[GNU xorriso home page](http://www.gnu.org/software/xorriso/xorriso_eng.html) +which gives some examples of xorriso usage, +its [man page](http://www.gnu.org/software/xorriso/man_1_xorriso.html), +and its +[installation instructions](http://www.gnu.org/software/xorriso/README_xorriso). + +----------------- + +GNU xorriso is feature-wise equivalent to the dynamic compilation of +libburnia libraries and libburnia program xorriso. +It restricts itself to a technical form where the legal commitments of the +libburnia project and the legal intentions of [FSF](http://www.fsf.org/) +match completely. + +Libburnia project is committed to provide support for this copy in the same +way as for its own software releases. It is further committed to keep its +own licenses open for obtaining future copies under GPLv2+.
