Convert ai1wm wpress archives to and from tar archives.
This script converts between the wpress archive format and the tar archive format. It is intended to be used as a filter, so it reads from standard input and writes to standard output.
The wpress archive format is a simple format for storing files in a directory structure, used by the All-in-One WP Migration plugin.
wpressarc --from-tar | --to-tar [OPTIONS] [FILE ...] < INPUT
One of the following options must be specified:
| Option | Description |
|---|---|
-f | --from-tar |
Convert from tar to wpress archive |
-t | --to-tar |
Convert from wpress to tar archive |
When converting from wpress to tar, the following options are also available:
| Option | Description |
|---|---|
-m | --mode MODE |
File mode for tar archive entries [default: 0644] |
-d | --dmode MODE |
Directory mode for tar archive entries [default: 0755] |
-u | --uid UID |
User ID for tar archive entries [default: 0] |
-g | --gid GID |
Group ID for tar archive entries [default: 0] |
-U | --owner OWNER |
User name for tar archive entries [default: root] |
-G | --group GROUP |
Group name for tar archive entries [default: root] |
For example, to convert a tar archive to a wpress archive:
wpressarc --from-tar < wordpress.tar > wordpress.wpress
To convert a wpress archive to a tar archive:
wpressarc --to-tar < wordpress.wpress > wordpress.tar
To extract a wpress archive:
wpressarc --to-tar < wordpress.wpress | tar -xvf -
To list the contents of a wpress archive:
wpressarc --to-tar < wordpress.wpress | tar -tvf -
To extract only files matching a pattern from an archive (wpress or tar):
wpressarc --to-tar '*.sql' < wordpress.wpress | tar -xvf -
Converting a wpress archive to a tar archive is lossy, because the wpress archive format does not store file permission, ownership, and other metadata, and it also does not store any metadata for the directories (in fact, it does not even store the directory entries).
When the FILE arguments are specified, they are interpreted as
patterns to match against the file names in the archive. If stdin
is seekable, i.e. if it is redirected directly from a file, then
the unmatched entries will be skipped entirely, which will be much
faster than reading and discarding the entries.
