After installing new software, an already opened terminal with zsh won't know about the new commands and cannot generate auto-complete for those. Apparently opening a new terminal fix the problem, but can the index (or whatever you call it) be rebuilt so that auto-complete will work on the old terminal?
I tried with compinit but that didn't help. Also, is there a way that is not shell-dependent? It's nice to have a way to verify the answer as well (except for uninstalling something and reinstalling it).
What I mean is after typing a few characters of a command's name, I can press Tab, and zsh should do the rest to pull up the full name.

To rebuild the cache of executable commands, use
rehashorhash -rf.Make sure you haven't unset the
hash_list_alloption (it causes even fewer disk accesses but makes the cache update less often).If you don't want to have to type a command, you can tell zsh not to trust its cache when completing by putting the following line in your
~/.zshrc¹:There is a performance cost, but it is negligible on a typical desktop setting today. (It isn't if you have
$PATHon NFS, or a RAM-starved system.)The
zstylecommand itself is documented in thezshmoduleman page. The styles values are documented in thezshcompsysandzshcompwidman pages, or you can read the source (here, of the_command_namesfunction). If you wanted some readable documentation… if you find some, let me know!¹ requires zsh≥4.3.3, thanks Chris Johnsen
