I want to tar the files foo and bar into a tar archive archive.tar, but I want them to appear, within the archive, as being within a directory, bazdir. Thus when I untar someplace I want bazdir to be created and foo and bar to be created within it.

How can I do that?

This would be the opposite of:

create flat tar archive: ignoring all parents when adding folders


You can use the --transform option. For example:

touch foo bar
tar cf archive.tar foo bar --transform 's,^,bazdir/,'
tar tvf archive.tar 
-rw-r--r-- tigger/tigger     0 2017-10-11 19:32 bazdir/foo
-rw-r--r-- tigger/tigger     0 2017-10-11 19:32 bazdir/bar

For more details and more complex options see How to create a common base folder with tar and how to rename folders? - on the sister site, ask ubuntu.

  • Note that --transform doesn't work with macOS tar. – Andreas Baumgart Mar 17 at 8:27
