Como parar a aparência de ^ T% na primeira linha quando abro uma nova guia lxterminal com ^ T em zsh?

Question

Etapas para reproduzir:

1. Tenha zsh como shell padrão.
2. Abra um novo terminal. por exemplo, com Ctrl + Alt + T .
3. Pressione Ctrl + Deslocar + T para abrir uma nova guia de terminal.
4. ^T% aparece como a primeira linha

Estou executando o Ubuntu 11.10 com lxde e zsh-4.3.11.

O terminal Gnome não tem esse problema.

Esse é um bug lxterminal.

Ele não aparece em outros shells porque o zsh é legal o suficiente para tentar mostrar a você caracteres ocultos mostrados pelo comando anterior quando você não inclui uma nova linha antes de emitir um prompt.

Se você digitar echo -n foo , verá foo% . O % indica que não havia nenhum caractere de nova linha. Acima, o que acontece é que as saídas lxterminal que ^T antes de executar o shell.

Em outros shells, em vez de ^T%\nprompt> , você vê ^Tprompt .

O Lxterminal tem outro bug BTW, pois ignora o valor de $SHELL .
