There is a file called โ€œ:qโ€!

Proof that even before IRC, people typed vi commands in the wrong window.

Edit: it disappeared! I guess it was an issue with archival, not with the original tape.

@samir Sort ofโ€ฆ

If I download http://squoze.net/UNIX/v4/:q and have a look:

```
$ cat /tmp/_q
UNIX Fourth Edition
===================

Here you can find the contents of
the [UNIX v4 tape](https://archive.org/details/utah_unix_v4_raw)
ready for bootstrapping, including a tar file of the filesystem.

* [unix_v4.tap](unix_v4.tap) is the original tape file in simh format
* [bootstrap](bootstrap) are the first 38400 bytes of the tape
* [disk.rk](disk.rk) is the rest of the tape, an RK05 image
* [unix_v4.tar](unix_v4.tar) is the filesystem extracted
* [install.ini](install.ini) is an ini file for simh to install the system
* [boot.ini](boot.ini) is an ini file for simh to boot the system
```

Looks like Markdown with the README content. If I look at that `unix_v4.tar`:

```
$ tar -tf unix_v4.tar | grep -F : | wc -l
0
```

@stuartl @samir The other give away (and this might be the OP's joke) is that vi on Unix V4 is an anachronism. vi was released as a part of 2BSD, which is an extension of V6/V7 Unix, and would not exist on a real V4 dump.
@overeducatedredneck @stuartl I did suspect it came later, but I didnโ€™t know, and honestly I was on my phone and jokes take precedence over facts. ๐Ÿ˜›
@samir @stuartl I think it makes the joke better ๐Ÿ˜‚
@samir legend has it one of the unix designer is still stuck in the tape, never having managed to exit vim.
@samir I think it's likely they were using vi and typed ":w :q" thinking that was the way to write and quit
