sy vault edit --help
sy-vault-edit 
Edit a resource. This will decrypt the resource to a temporary file, open up the $EDITOR you have specified, and re-
encrypt the changed content before deleting it on disk.

USAGE:
    sy vault --config-file <path> edit [FLAGS] [OPTIONS] <path>

FLAGS:
    -h, --help              Prints help information
        --no-create         If set, the resource you are editing must exist. Otherwise it will be created on the fly,
                            allowing you to add new resources by editing them.
        --no-try-encrypt    Unless set, we will assure encryption works prior to launching the editor. This assures you
                            do not accidentally loose your edits.

OPTIONS:
    -e, --editor <editor>    The path to your editor program. It receives the decrypted content as first argument and is
                             expected to write the changes back to that file before quitting. [default: vim]

ARGS:
    <path>    Either a vault-relative path to the file as displayed by 'vault show',a vault-relative path with the
              '.gpg' suffix, or an absolute path with or without the '.gpg' suffix.
