\fB\-find\fR iso_rr_path [-name pattern] [-type t] [-exec action [params]] --
\fB\-find\fR iso_rr_path [test [test ...]] [-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.
Tests are optional. If they are omitted then action is applied to all file
objects. If tests are given then action is applied only if all of them
match the file object. Available tests are:
.br
The optional -type test restricts matching to files of the given type:
-name pattern
.br
Pattern is not expanded but used for comparison with
the particular file names of the eventual directory tree underneath
iso_rr_path.
.br
-type type_letter
.br
matches only files files of the given type:
"block", "char", "dir", "pipe", "file", "link", "socket",
"Xotic" which eventually matches what is not matched by the other types.
.br
Only the first letter is interpreted. E.g.: -find / -type d
.br
If a file matches then the action is performed. Default action is "echo",
-damaged
.br
matches only files which use data blocks marked as damaged by a previous
run of -check_media. The damage info vanishes when a new ISO image gets
loaded.
.br
-undamaged
.br
matches only files which use data blocks outside the areas marked as damaged.
.br
-lba_range start_lba block_count
.br
matches only files which use data blocks within the range of start_lba
and start_lba+block_count-1.
.br
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.

"report_damage" classifies files whether they hit a data block that is
marked as damaged. The result is printed together with the eventual address
of the first damaged byte, the maximum span of damages, file size, and the
path of the file.
.br
E.g.:
.br
-find / -damaged -exec report_damage

"find" performs another run of -find on the matching file address. It accepts
the same params as -find, except iso_rr_path.
