Re: Delete
You don't ever need to delete.
Hmm, how many ways is that wrong, lets think of a few ...
1) It's illegal to keep personal information that's no longer needed.
2) disk space isn't infinite, but the ability to use it is. For example, I tend to rip DVDs and store just the film/programs on my media server with the physical disks put out of the way - it's both more convenient, and a better experience stripping all the "coming soon trailers for stuff that came out decades ago, and the obligatory 'you're a criminal' bits". That takes "a few gigs" each time with stuff I will never need again (and if I did, it's on the original DVD). I only have a 2TB SSD in my laptop, spinning rust (if I could afford to waste it like that) would be a lot slower over USB.
3) In a past life, we had an accounting system I was sysadmin for - it generated gigs of data when 18G was about the limit if you had deep pockets. We often made copies of the database in order to test something. Ditto it not being practical to keep everything.
4, 5, 6, 7,...) Some of us have discovered something called ... a backup. Used to have cabinets full of the tapes for said system in #3
Definitely not with a wildcard. Definitely not with a -f.
Hmm, so are you going to delete hundreds, thousands, of files individually ? Ditto hitting Y "a few times" when the OS seems to think it's fun to keep asking ?
The general principle - move something rather than delete it - yes, fully agree. But unless you have an unlimited budget for storage and are willing to accept the risks of constantly upgrading the hardware, you have to delete stuff sometime when you're done with it.
