[-v] [-q] [--numeric-ids] [--no-symlinks] [-f file]
bup meta --start-extract
[-v] [-q] [--numeric-ids] [--no-symlinks] [-f file]
bup meta --finish-extract
[-v] [-q] [--numeric-ids] [-f file]
bup meta --edit
[--set-uid uid | --set-gid gid | --set-user user | --set-group group | ...] <paths...>
DESCRIPTION
bup meta creates, extracts, or otherwise manipulates metadata archives. A metadata archive contains the
metadata information (timestamps, ownership, access permissions, etc.) for a set of filesystem paths.
See bup-restore(1) for a description of the way ownership metadata is restored.
OPTIONS
-c, --create
Create a metadata archive for the specified paths. Write the archive to standard output unless
--file is specified.
-t, --list
Display information about the metadata in an archive. Read the archive from standard input unless
--file is specified.
-x, --extract
Extract a metadata archive. Conceptually, perform --start-extract followed by --finish-extract.
Read the archive from standard input unless --file is specified.
--start-extract
Build a filesystem tree matching the paths stored in a metadata archive. By itself, this command
does not produce a full restoration of the metadata. For a full restoration, this command must be
followed by a call to --finish-extract. Once this command has finished, all of the normal files
described by the metadata will exist and be empty. Restoring the data in those files, and then
calling --finish-extract should restore the original tree. The archive will be read from standard
input unless --file is specified.
--finish-extract
Finish applying the metadata stored in an archive to the filesystem. Normally, this command
should follow a call to --start-extract. The archive will be read from standard input unless
--file is specified.
--edit Edit metadata archives. The result will be written to standard output unless --file is specified.
-f, --file=filename
Read the metadata archive from filename or write it to filename as appropriate. If filename is
"-", then read from standard input or write to standard output.
-R, --recurse
Recursively descend into subdirectories during --create.
--xdev, --one-file-system
don't cross filesystem boundaries -- though as with tar and rsync, the mount points themselves
will still be handled.
--numeric-ids
Apply numeric IDs (user, group, etc.) rather than names during --extract or --finish-extract.
--symlinks
Record symbolic link targets when creating an archive, or restore symbolic links when extracting
an archive (during --extract or --start-extract). This option is enabled by default. Specify
--no-symlinks to disable it.
--paths
Record pathnames when creating an archive. This option is enabled by default. Specify --no-paths
to disable it.
--set-uid=uid
Set the metadata uid to the integer uid during --edit.
--set-gid=gid
Set the metadata gid to the integer gid during --edit.
--set-user=user
Set the metadata user to user during --edit.
--unset-user
Remove the metadata user during --edit.
--set-group=group
Set the metadata user to group during --edit.
--unset-group
Remove the metadata group during --edit.
-v, --verbose
Be more verbose (can be used more than once).
-q, --quiet
Be quiet.
EXAMPLES
# Create a metadata archive for /etc.
$ bup meta -cRf etc.meta /etc
bup: removing leading "/" from "/etc"
# Extract the etc.meta archive (files will be empty).
$ mkdir tmp && cd tmp
$ bup meta -xf ../etc.meta
$ ls
etc
# Restore /etc completely.
$ mkdir tmp && cd tmp
$ bup meta --start-extract -f ../etc.meta
...fill in all regular file contents using some other tool...
$ bup meta --finish-extract -f ../etc.meta
# Change user/uid to root.
$ bup meta --edit --set-uid 0 --set-user root \
src.meta > dest.meta
