Hello, I've had this problem multiple times, and now I have a confirmation other people had it too: https://serverfault.com/questions/803831/tar-extract-a-member-reliably-with-possible-leading-dot-slash
I'll quote andrewsh's problem description: > $ tar tvf archive1.tar > -rw-r--r-- root/root 567 2016-09-18 14:28 member1 > -rw-r--r-- root/root 1696 2016-09-18 14:28 member2 > $ tar tvf archive2.tar > -rw-r--r-- root/root 567 2016-09-18 14:28 ./member1 > -rw-r--r-- root/root 1696 2016-09-18 14:28 ./member2 > > How to extract member1 reliably from either of two archives?

I feel that GNU tar needs to either support forms with and without ./ prefix, or have a switch to enable such. Thank you.
