I have a directory with database backups stored in data-atm1-YYYYMMDDHHMMSS.sql.gz filename format.

Q: How do I delete all files but I need to keep last X files? (ordered in descendant order by filename).

@bac0n do what manually? if you are referring to the linked question, my zsh answer could be modified to use lexical name order as *(On[11,-1]) (although probably mtime would also work here - unless the names of the backups do not correspond to their true dates) – steeldriver Mar 17 '21 at 14:32

@bac0n doh! yes, in that sense I "did it manually" - I just wasn't sure it counted as an exact dupe (since the ordering criterion is - at least nominally - different) – steeldriver Mar 17 '21 at 14:52
