To change the executable name, use -n/--name:
deno install --allow-net --allow-read -n serve https://deno.land/std/http/file_server.ts
The executable name is inferred by default:
- Attempt to take the file stem of the URL path. The above example would
become 'file_server'.
- If the file stem is something generic like 'main', 'mod', 'index' or 'cli',
and the path has no parent, take the file name of the parent path. Otherwise
settle with the generic name.
- If the resulting name has an '@...' suffix, strip it.
To change the installation root, use --root:
deno install --allow-net --allow-read --root /usr/local https://deno.land/std/http/file_server.ts
The installation root is determined, in order of precedence:
- --root option
- DENO_INSTALL_ROOT environment variable
- $HOME/.deno
These must be added to the path manually if required.")

This commands supports cross-compiling to different target architectures using `--target` flag.
On the first invocation with deno will download proper binary and cache it in $DENO_DIR. The
aarch64-apple-darwin target is not supported in canary.
It is possible to use \"lite\" binaries when compiling by passing `--lite` flag; these are stripped down versions
of the deno binary that do not contain built-in tooling (eg. formatter, linter). This feature is experimental.
