It is “backwards” from some other commands — usually you run copy/rsync/link from source to destination, but with tar the destination (tarball) is specified before the source (directory/files).
That, and the flags not needing dashes always just throws me for a loop.
And the icing on the cake is that I don’t use tar for tarring that often, so I lose all muscle memory (untaring a tgz or tar.bz2 is frequent enough that I can usually get that right at least…).
I almost never create a tarball, so I have to look up the syntax for that. Which is as simple as man tar. But as far as extracting it almost couldn’t be easier, tar xf <tarball> and call it a day. Or if you want to list the contents without extracting, tar tf <tarball>. Unless you’re using an ancient version of tar, it will detect and handle whatever compression format you’re using without you having to remember if you need z or J or whatever.
Nobody wants to deliberately use the wrong compression type when extracting, so modern tar will figure out the compression itself if you just point it at a file. So tar -xf filename works on almost anything. You don’t need to remember which flag to use on a .tar.bz2 file and which one for a .tar.xz file.
I feel very confident in my understanding of random 8 bit CPUs and their support chips, but asking me to center a div is like this xkcd.

YOU FOOL! THE ACTUAL COMMAND WAS
tar -?I’ve never understood why people are so intimidated by tar

tar -eXtract Ze Vucking File
I was about to say
tar -CompressZeVuckingFile; great mnemonic and I use it every time!Thanks! This will definitely help me to remember it from now on.
