Like -alter_date but affecting all files below eventual directories.
.TP
\fB\-find\fR iso_rr_path [-name pattern] [-exec action [params]] --
A very restricted substitute for shell command find in the ISO image.
It performs an action on matching file objects at or below iso_rr_path.
.br
Optional -name pattern is not expanded but used for comparison with
the particular file names of the eventual directory tree underneath
iso_rr_path. If no -name pattern is given, then any file name matches.
.br
If a file matches then the action is performed. Default action is "echo",
i.e. to print the address of the found file. Other actions are certain
xorriso commands which get performed on the found files. These commands
may have specific parameters. See also their particular descriptions.
.br
"chown" and "chown_r" change the ownership and get the user id as param.
E.g.: -find -exec chown thomas
.br
"chgrp" and "chgrp_r" change the group attribute and get the group id as param.
E.g.: -find -exec chgrp_r staff
.br
"chmod" and "chmod_r" change access permissions and get a mode string as param.
E.g.: -find -exec chmod a-w,a+r
.br
"alter_date" changes the timestamps.
It gets a type character and a timestring as params.
.br
E.g.: -find -exec alter_date_r "m" "Dec 30 19:34:12 2007"
.br
"lsdl" prints file information like shell command ls -dl. It gets no params.
E.g.: -find -exec lsdl
.br
"find" performs another run of -find on the matching file address. It accepts
the same params as -find, except iso_rr_path.
.br
E.g.: -find -name '???' -exec find -name '[abc]*' -exec chmod a-w,a+r
.br
If not used as last command in the line then the argument list
needs to get terminated by "--".

/* Command line oriented batch and dialog tool which creates, loads,
manipulates and burns ISO 9660 filesystem images.
Copyright 2007 Thomas Schmitt, <scdbackup@gmx.net>
Copyright 2007-2008 Thomas Schmitt, <scdbackup@gmx.net>
Initial code of this program was derived from program src/askme.c out
of scdbackup-0.8.8, Copyright 2007 Thomas Schmitt, BSD-License.
Provided under GPL version 2, with the announcement that this might
get changed in future. I would prefer BSD or a modifyied LGPL with no
get changed in future. I would prefer BSD or a modified LGPL with no
option to choose any kind of future GPL version.
(This announcement affects only future releases of xorriso.
If you obtain a copy licensed as "GPL version 2" then this license is
not revocable for that particular copy, of course.)
Overview of xorriso architecture:
libburn provides the ability to read and write data.
libisofs interprets and manipulates ISO 9660 directory trees. It generates
the output stream which is handed over to libburn.
libisoburn encapsulates the connectivity issues between libburn and
libisofs. It also enables multi-session emulation on overwritable media
and random access file objects.
xorriso is intended as reference application of libisoburn.
xorrisoburn.[ch] encapsulate any usage of the libraries by xorriso.
xorriso.h exposes the public functions of xorriso which are intended
to be used by programs which link with xorriso.o. These functions are
direct equivalents of the xorriso interpreter commands.
There is also the API for handling event messages.
xorriso_private.h is not to be included by other software. It encapsulates
the inner interfaces of xorriso.
xorriso.c provides the command interpreter as described in xorriso.1.
It performs any activity that does not demand a reference to a symbol
of the library APIs. This includes:
- Interpretation of user input from arguments, dialog, and scripting.
- Output of result text and event messages.
- POSIX filesystem operations.
- Public functions which perform the particular xorriso commands.
- The main() function, if enabled by #define Xorriso_with_maiN.
