I'm trying to remotely launch and debug a new process with <code style="margin: 0px; padding: 1px 5px; border: 0px; font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, sans-serif; font-size: 13px; font-style: inherit; font-variant-caps: inherit; line-height: inherit; vertical-align: baseline; background-color: rgb(239, 240, 241); white-space: pre-wrap;" class="">lldb</code> without
much success.</p><p style="margin: 0px 0px 1em; padding: 0px; border: 0px; font-family: Arial, 'Helvetica Neue', Helvetica, sans-serif; font-size: 15px; line-height: inherit; vertical-align: baseline; clear: both; color: rgb(36, 39, 41);" class="">
Attaching to an already launched process works well by running these commands:</p>

But if I want <code style="margin: 0px; padding: 1px 5px; border: 0px; font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, sans-serif; font-size: 13px; font-style: inherit; font-variant-caps: inherit; line-height: inherit; vertical-align: baseline; background-color: rgb(239, 240, 241); white-space: pre-wrap;" class="">debugserver</code> to
launch the executable by itself I'm running into troubles. Especially, I have no clue what arguments should I pass to <code style="margin: 0px; padding: 1px 5px; border: 0px; font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, sans-serif; font-size: 13px; font-style: inherit; font-variant-caps: inherit; line-height: inherit; vertical-align: baseline; background-color: rgb(239, 240, 241); white-space: pre-wrap;" class="">target

According to <a href="https://lldb.llvm.org/remote.html" style="margin: 0px; padding: 0px; border: 0px; font-family: inherit; font-size: inherit; font-style: inherit; font-variant-caps: inherit; line-height: inherit; vertical-align: baseline; color: rgb(0, 119, 204); text-decoration: none; cursor: pointer;" class="">this

If I set the target to a local file (such as a local copy of the remote's loader executable) without using <code style="margin: 0px; padding: 1px 5px; border: 0px; font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, sans-serif; font-size: 13px; font-style: inherit; font-variant-caps: inherit; line-height: inherit; vertical-align: baseline; background-color: rgb(239, 240, 241); white-space: pre-wrap;" class="">-r</code>,

What are the correct commands I need to use in order to launch a remote process?</p>
