\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 [-name pattern] [-exec action [params]] --
\fB\-find\fR iso_rr_path [-name pattern] [-type t] [-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
@ -598,32 +598,47 @@ 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
The optional -type test restricts matching to files of the given type:
"block", "char", "dir", "pipe", "file", "link", "socket", "Xotic",
where "X" 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",
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
"chown" and "chown_r" change the ownership and get the user id as param. E.g.:
.br
-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
E.g.:
.br
-find / name 'news*' -type d --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
E.g.:
.br
"alter_date" changes the timestamps.
It gets a type character and a timestring as params.
-find / -exec chmod a-w,a+r
.br
E.g.: -find -exec alter_date_r "m" "Dec 30 19:34:12 2007"
"alter_date" and "alter_date_r" change the timestamps.
They get a type character and a timestring as params.
E.g.:
.br
"lsdl" prints file information like shell command ls -dl. It gets no params.
E.g.: -find -exec lsdl
-find / -exec alter_date "m" "Dec 30 19:34:12 2007"
.br
"lsdl" prints file information like shell command ls -dl.
E.g.:
.br
-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.
E.g.:
.br
E.g.: -find -name '???' -exec find -name '[abc]*' -exec chmod a-w,a+r
-find / -name '???' -type d -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 "--".
