Difference between two .tar.gz file lists on linux

Question

Having two different .tar.gz files: The second .tar.gz is the subset of first .tar.gz.

I need a single line command to find the missing files in second .tar.gz.

E.g.:

1.tar.gz file list:

1.jsp
2.txt
3.htm

2.tar.gz file list:

1.jsp
3.htm

output should be:

2.txt

Just list the contents and do diff:

diff <(tar -tvf 1.tar.gz | sort) <(tar -tvf 2.tar.gz | sort)

I get "invalid tar magic" with `tar -tvf 1.tar.gz` in bash. When I do `tar -tzvf 1.tar.gz` it works. – FlexMcMurphy Jan 04 '21 at 01:24
@FlexMcMurphy Looks like your tar doesn't support all features. Is it a busybox (which is [known to lack this](https://unix.stackexchange.com/a/249357/72606)? – P.P Jan 04 '21 at 08:57

That's exactly what it is! I'm using Busybox on OpenWrt. I'm glad I figured out how to modify your command to my more limited environment. – FlexMcMurphy Jan 05 '21 at 21:42
