When extracting files from a tar archive, it's handy to be able to use
wildcards.
You have to
protect them (8.14)
from the shell, so that they are
passed directly to tar.
However, in general tar don't understand wildcards. There's a
terribly ugly hack that you can use to select the files you want
anyway. Try a command like this:
`...` |
% tar xvf /dev/rst0 `tar tf /dev/rst0 | egrep 'lib/(foo|bar)'` |
|---|
What you're doing here is using tar
twice. tar t will print the names of all the files
on the tape. The pattern supplied to egrep (27.5) selects the pathnames
containg lib/foo or lib/bar, and the
resulting filenames are passed to the first tar command,
which actually extracts the files from the archive.
