I've memorized a total of two commands from decompressing things (`tar xfv $file` and `unzip $file`) and one for compressing (`tar cf $archive.tar $file1 $file2 $directory`) which seems to have done everything I've wanted for more than 20 years of unix usage. Is there something I'm missing out on? Sometimes, a `gunzip` or `7z` has been needed, but they are far apart that I can look it up each time. I'm not sure how I can save hours of time as non-tar or non-zip files is not something I often come across.
