Tmux - Teclas de seta retornam dados brutos / caracteres não-escapados ^ [[A ^ [[B ^ [[D ^ [[C

Question

Acabei de atualizar para o Debian / Linux 9 (Stretch) e estou no processo de configurar tudo. Até agora só instalei o vim e o tmux. Meu problema é que, quando eu uso as teclas de seta, eles retornam dados brutos / caracteres não-escapados.

• Seta para cima retorna: ^ [[A
• Seta para baixo retorna: ^ [[B
• A seta para a ESQUERDA retorna: ^ [[D
• Seta para a DIREITA retorna: ^ [[C

Eu não posso ir para a esquerda ou para a direita em uma linha, ou usar setas para cima e para baixo para percorrer meus comandos anteriores / bash history A QUALQUER MOMENTO eu uso o tmux para QUALQUER COISA.

Meu arquivo .bashrc.

# don't put duplicate lines or lines starting with space in the history.

Corrigido ao mudar de bash para zsh - link

Bash e Zsh são os dois shells para seus terminais. Bash ou o Bourne-Again SHell, é o padrão na maioria dos sistemas devido a motivos de compatibilidade com sh que era praticamente o único shell em seu tempo. ... Bash e Zsh são bot inegavelmente poderosos com poder de script ainda mais poderoso. - link

Se você mudar para o zsh, confira prezto - link

Prezto é o framework de configuração para [Zsh] [1]; Ele enriquece o ambiente de interface da linha de comandos com padrões, aliases, funções, preenchimento automático e temas imediatos. - Prezto README.md
