\fB\-alter_date_r\fR type timestring iso_rr_path [***]
Like -alter_date but affecting all files below eventual directories.
.TP
\fB\-find\fR iso_rr_path [test [test ...]] [-exec action [params]] --
A very restricted substitute for shell command find in the ISO image.
\fB\-find\fR iso_rr_path [test [op] [test ...]] [-exec action [params]] --
A 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
If not used as last command in the line then the argument list
needs to get terminated by "--".
.br
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:
objects. If tests are given then they form together an expression.
The action is applied only if the expression matches the file object. Default
expression operator between tests is -and, i.e. the expression matches only
if all its tests match.
.br
-name pattern
Available tests are:
.br
\fB\-name\fR pattern :
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:
\fB\-type\fR type_letter :
Matches files files of the given type:
"block", "char", "dir", "pipe", "file", "link", "socket", "eltorito",
"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
-damaged
.br
matches only files which use data blocks marked as damaged by a previous
\fB\-damaged\fR :
Matches 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
\fB\-pending_data\fR :
Matches files which get their content from outside the loaded ISO image.
.br
matches only files which use data blocks outside the areas marked as damaged.
\fB\-lba_range\fR start_lba block_count :
Matches files which use data blocks within the range of start_lba
and start_lba+block_count-1.
.br
-lba_range start_lba block_count
\fB\-has_acl\fR :
Matches files which have a non-trivial ACL.
.br
matches only files which use data blocks within the range of start_lba
and start_lba+block_count-1. A negative start_lba matches those files which
would not match the range given by its positive counter part.
\fB\-has_xattr\fR :
Matches files which have xattr name-value pairs from user namespace.
.br
-has_acl , -has_no_acl
\fB\-has_aaip\fR :
Matches files which have ACL or any xattr.
.br
match files which have resp. have not a non-trivial ACL.
\fB\-has_filter\fR :
Matches files which are filtered by -set_filter.
.br
-has_xattr , -has_no_xattr
\fB\-decision\fR "yes"|"no" :
If this test is reached then the evaluation ends immediatly and action
is performed if the decision is not "no", "0", or "false". See operator -if.
.br
match files which have resp. have not xattr name-value pairs
from user namespace.
Available operators are:
.br
-has_aaip , -has_no_aaip
\fB\-not\fR :
Matches if the next test or sub expression does not match.
Several tests do this specifically:
.br
match files which have ACL or any xattr resp. have neither of them.
-undamaged, -lba_range with negative start_lba, -has_no_acl, -has_no_xattr,
-has_no_aaip, -has_no_filter
.br
-has_filter , -has_no_filter
\fB\-and\fR :
Matches if both neighboring tests or expressions match.
.br
match files which are filtered by -set_filter resp. are not.
\fB\-or\fR :
Matches if at least one of both neighboring tests or expressions matches.
.br
\fB\-sub\fR ... \fB\-subend\fR :
Enclose a sub expression which gets evaluated first before it
is processed by neighboring operators. The same meaning have "(" and ")".
.br
Normal precedence is: -not, -or , -and.
.br
\fB\-if\fR ... \fB\-then\fR\ ... \fB\-elseif\fR ... \fB\-then\fR ...
\fB\-else\fR ... \fB\-endif\fR :
Enclose one or more sub expressions. If the -if expression matches, then
the -then expression is evaluated as the result of the whole expression
up to -endif. Else the next -elseif expression is evaluated and eventually
its -then expression. Finally in case of no match, the -else expression
is evaluated.
There may be more than one -elseif. Neither -else nor -elseif are mandatory.
If -else is missing and would be hit, then the result is a non-match.
.br
-if expressions are the main use case for the test -decision.
Default action is "echo",
Default action is \fBecho\fR,
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.:
\fBchown\fR and \fBchown_r\fR change the ownership and get the user id
as parameter. E.g.: -exec chown thomas --
.br
-find / -exec chown thomas --
\fBchgrp\fR and \fBchgrp_r\fR change the group attribute and get the group id
as paramieter. E.g.: -exec chgrp_r staff --
.br
"chgrp" and "chgrp_r" change the group attribute and get the group id as param.
E.g.:
\fBchmod\fR and \fBchmod_r\fR change access permissions and get a mode string
as parameter. E.g.: -exec chmod a-w,a+r --
.br
-find / name 'news*' -type d -exec chgrp_r staff --
\fBalter_date\fR and \fBalter_date_r\fR change the timestamps. They get a type
character and a timestring as parameters.
.br
"chmod" and "chmod_r" change access permissions and get a mode string as param.
E.g.:
E.g.: -exec alter_date "m" "Dec 30 19:34:12 2007" --
.br
-find / -exec chmod a-w,a+r --
\fBlsdl\fR prints file information like shell command ls -dl.
.br
"alter_date" and "alter_date_r" change the timestamps.
They get a type character and a timestring as params.
E.g.:
\fBcompare\fR performs command -compare with the found file address as
iso_rr_path and the corresponding file address below its argument
disk_path_start. For this the iso_rr_path of the -find command gets
replaced by the disk_path_start.
.br
-find / -exec alter_date "m" "Dec 30 19:34:12 2007" --
E.g.: -find /thomas -exec compare /home/thomas --
.br
"lsdl" prints file information like shell command ls -dl.
E.g.:
\fBupdate\fR performs command -update with the found file address as
iso_rr_path. The corresponding file address is determined like with above
action "compare".
.br
-find / -exec lsdl --
\fBrm\fR removes the found iso_rr_path from the image if it is not a directory
with files in it. I.e. this "rm" includes "rmdir".
.br
"compare" performs command -compare with the found file address as iso_rr_path
and the corresponding file address below its argument disk_path_start. For this
the iso_rr_path of the -find command gets replaced by the disk_path_start.
E.g.:
\fBrm_r\fR removes the found iso_rr_path from the image, including whole
directory trees.
.br
-find / -exec compare /home/thomas --
.br
"update" performs command -update with the found file address as iso_rr_path.
The corresponding file address is determined like with above "compare".
.br
E.g.:
.br
-find / -exec update /home/thomas --
.br
"rm" removes the found iso_rr_path from the image if it is not a directory with
files in it. I.e. this "rm" includes "rmdir".
.br
E.g.:
.br
-find / -name *.doc -exec rm --
.br
"rm_r" removes the found iso_rr_path from the image, including whole directory
trees.
.br
E.g.:
.br
-find /uh/oh -name *private* -exec rm_r --
.br
"report_damage" classifies files whether they hit a data block that is
\fBreport_damage\fR 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 --
.br
"report_lba" prints files which are associated to image data blocks.
\fBreport_lba\fR prints files which are associated to image data blocks.
It tells the logical block address, the block number, the byte size,
and the path of each file. There may be reported more than one
line per file if the file is very large. In this case each line has a
different extent number in column "xt".
.br
E.g.:
\fBgetfacl\fR prints access permissions in ACL text form to the result channel.
.br
-find / -lba_range 302000 50000 -exec report_lba --
.br
"getfacl" prints access permissions in ACL text form to the result channel.
.br
E.g.:
.br
-find / -has_acl -exec getfacl
.br
"setfacl" attaches ACLs after removing eventually exiting ones. The new
\fBsetfacl\fR attaches ACLs after removing eventually exiting ones. The new
ACL is given in text form as defined with option -setfacl.
.br
E.g.:
E.g.: -exec setfacl u:lisa:rw,u::rw,g::r,o::-,m::rw --
.br
-find /work -exec setfacl u:lisa:rw,u::rw,g::r,o::-,m::rw --
\fBgetfattr\fR prints eventual xattr name-value pairs to the result channel.
.br

\fBsetfattr\fR sets or deletes xattr name value pairs.
.br
E.g.:
E.g.: -find / -has_xattr -exec setfattr --remove-all '' --
.br
-find / -has_xattr -exec getfattr --
\fBset_filter\fR applies or removes filters.
.br
"setfattr" sets or deletes xattr name value pairs.
E.g.: -exec set_filter --zisofs --
.br
E.g.:
\fBshow_stream\fR shows the content stream chain of a data file.
.br
-find / -has_xattr -exec setfattr --remove-all '' --
.br
"set_filter" applies or removes filters (see -external_filter).
.br
E.g.:
.br
-find / -type f -exec set_filter gzip --
.br
"show_stream" shows the content stream chain of a data file.
.br
E.g.:
.br
