>rsync which is well documented

Here is the man page entry for the --delete flag:

--delete is used. This option is mutually exclusive with --delete-during, --delete-delay, and --delete-after.

Hilarious!

Reading and understanding the rsync command would take much more than 10 mins and I am not a total newb here.

What command? Just to clarify there is no example command we’re discussing here. You’re just cherry picking results exclusively from the man page and then arguing that chatgpt is better because it gets to use example documentation from the internet. Well I get to use examples from the internet too.

A search query takes a matter of seconds to type in, select a result and read. No doubt still under 10 minutes.

But still to my original point it’s insanely more expensive to have chatgpt look it up. This doesn’t bother you because you are privileged enough to waste money there. If time is money then IMO the only valuable time I have with my money is when it’s gaining interest and not being spent.

You can abstract away all the “but I had to scroll down the page and click a different result” steps as “time savings” all you want, but no one was wasting a ton of time there for already well established tools. That is a deluded myth.

I’m not sure I even grasped your point. The delete flag is pretty self explanatory and gives you options for more granularity. Why does that take greater than 10 mins? What is the issue with that entry?

Here is what I get when I type `man rsync`:

``` --delete This tells rsync to delete extraneous files from the receiving side (ones that aren't on the sending side), but only for the directories that are being synchronized. You must have asked rsync to send the whole directory (e.g. "dir" or "dir/") without using a wildcard for the directory's contents (e.g. "dir/*") since the wildcard is expanded by the shell and rsync thus gets a request to transfer individual files, not the files' parent directory. Files that are excluded from the transfer are also excluded from being deleted unless you use the --delete-excluded option or mark the rules as only matching on the sending side (see the include/exclude modifiers in the FILTER RULES section).

              Prior to rsync 2.6.7, this option would have no effect unless
              --recursive was enabled.  Beginning with 2.6.7, deletions will
              also occur when --dirs (-d) is enabled, but only for directories
              whose contents are being copied.

              This option can be dangerous if used incorrectly! It is a very
              good idea to first try a run using the --dry-run (-n) option to
              see what files are going to be deleted.

              If the sending side detects any I/O errors, then the deletion of
              any files at the destination will be automatically disabled.
              This is to prevent temporary filesystem failures (such as NFS
              errors) on the sending side from causing a massive deletion of
              files on the destination.  You can override this with the
              --ignore-errors option.

              The --delete option may be combined with one of the --delete-
              WHEN options without conflict, as well as --delete-excluded.
              However, if none of the --delete-WHEN options are specified,
              rsync will choose the --delete-during algorithm when talking to
              rsync 3.0.0 or newer, or the --delete-before algorithm when
              talking to an older rsync.  See also --delete-delay and
              --delete-after.

```

I pasted the results of typing man rsync into my macbook’s terminal. I looked up the —delete parameter and pasted the entry. Not sure why your entry was more useful - perhaps a version issue (which is at the root of the painful time I have spent trying to learn how to do something trivial).

Later in the man page, it gives examples and totally fails to explain those examples. And yes, for someone who is going to be doing this frequently and professionally. They should understand this deeply and spending the hours required to be fluent in a command with a kitchen sink full of parameters. I, on the other hand, will be executing these commands maybe a few times in a year.

The more I think about it, the more I think the solution here is to use LLM‘s to write better documentation with lenses for different types of users with different needs.
