Re: [Help-tar] compress list of files, when root folder is a symlink

[Reuti]

Hi,

Interesting that:

cd /tmp/test/uncompress-folder
tar tf corrupted-tar.tar.gz > included.txt

lists the expected three entries and fails do perform:

tar -T included.txt -xf corrupted-tar.tar.gz

while it only creates the symlink to the directory. But you can delete then the 
first line containing the symlink after this first run, and then the two files 
will be extracted in the second run.
