"The world should conform to my expectations, not long-standing conventions!"
But if you engage your thinking meat, you might just discover the magic of
alias untar='tar xvf'."long-standing conventions" is how you end up with Internet Explorer still pre-installed on Windows Server 2025.
And when was the last time you used the tar "tape archiver" to archive things on tape?
Magnetic tapes are still being used as long-term storage, as backups for example. They are inexpensive, compact, have zero moving parts, and are more durable than optical media. All you have to do is keep them in a location that is around room temperature, relatively dry, and away from magnets.
But that's not really what
tardoes. It simply collects the input files and writes them to a single contiguous data stream -- a file not unlike an actual tape. It's worked like that for, I shit you not, 45 years, and it is very much a single project holding up modern technology situation. I fear to imagine what would happen if it were to change.What the fuck zero moving parts? Are you high?
That would be the sticky tape. Also good for long term storage.
You may not have heard this, but tar can be used to work with non-tape archives.
In fact, non-tape archives are the overwhelmingly popular workflow.
Does having to explain the history of a tool to understand why it works that way make it more or less useful?
Neither, but understanding that and the ubiquity of that tool might help understand why it can't simply be changed
Why are long standing conventions a good thing? Slavery was a longstanding convention.
No human rights are violated by tar functioning the way it does, but changing it would cause a lot of problems without good reason since you could just as easily write an alias or wrapper to simplify the usage
