This prompt takes up two lines. At its most verbose, it looks like this:
|
|
|
|
<user> at <host> in <cwd> on <repo>(<branch>)
|
|
%
|
|
|
|
By default, <host> is only shown when the SSH_CONNECTION variable is set; in
|
|
other words, when this shell session was opened via an SSH connection. The
|
|
prompt will also show the current repository and branch using vcs_info if the
|
|
current directory is in a repo.
