.br
"chown" and "chown_r" change the ownership and get the user id as param. E.g.:
.br
-find / -exec chown thomas
-find / -exec chown thomas --
.br
"chgrp" and "chgrp_r" change the group attribute and get the group id as param.
E.g.:
.br
-find / name 'news*' -type d -exec chgrp_r staff
-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.:
.br
-find / -exec chmod a-w,a+r
-find / -exec chmod a-w,a+r --
.br
"alter_date" and "alter_date_r" change the timestamps.
They get a type character and a timestring as params.
E.g.:
.br
-find / -exec alter_date "m" "Dec 30 19:34:12 2007"
-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
-find / -exec lsdl --
.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.:
.br
-find / -exec compare /home/thomas
-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
-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
"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
-find / -name '???' -type d -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 "--".
