Hi,
I'd like to unpack tar archives in tup. Here is what I came up with:
$ cat Tupfile
run ./Tupfile.sh
$ cat Tupfile.sh
#!/bin/bash
shopt -s nullglob
for i in *.tar *.tgz *.tar.gz *.tbz *.tar.bz; do
echo ": $i |> tar -xmf $i |> $(tar -tf $i | tac | awk 'BEGIN {ORS =
" "} a !~ $0; { a = $0 }')"
done
Note that reversing the file together with the awk one-liner just takes
care that only those lines that contain leaves remain in the tar -tf
output, e.g. converting
$ tar -tf sometar.tar
./
./somedir/
./somedir/somefile
./somefile
to
$ tar -tf sometar.tar | tac | awk 'BEGIN {ORS = " "} a !~ $0; { a = $0
}')"
./somefile ./somedir/somefile
This works pretty well and seems to be a rather generic solution as long
as the tar archives are relative, but fails when they contain empty
directories: Then, tup complains that directories may only be created
temporarily. Obviously, targets may only be files in tup, not directories.
My question (finally :-)) Is there a compelling reason why tup doesn't
accept directories as targets?
Thanks and regards,
Chris
