No vim eu uso o seguinte comando para compilar um arquivo tex:
pdflatex\ \-file\-line\-error\ \-shell\-escape\ \-interaction=nonstopmode\ $*\\|\ grep\ \-P\ ':\d{1,5}:\ '
isso funciona em termos de colocar os erros em uma janela de correção rápida (se você não usar o vim, ignore esta frase). O único problema é que eu gostaria de ver a saída de látex vindo na tela enquanto o documento está compilando (agora o grep engole toda a saída).
O que devo mudar para que isso aconteça? Eu já tentei canalizar tudo para tail , mas sem sucesso.

O Vim só deve exibir:
main.tex l.47 undefined control sequence
No entanto, gosto de ver a saída para que eu tenha algum feedback sobre qual página está sendo compilada, etc.
Já tentou usar errorformat em vez de grep'ing a saída? C.f. link . É especialmente útil se você configurar o comando make ( link ).
Obrigado pela saída atualizada, romeovs. Parece que você deseja ter algo como:
set errorformat=%E%f:%l:\ %m%C1.%l\ %Z
Eu não posso testar isso, mas com base na saída, parece ser o que você quer.
Você deve realmente dar uma olhada em borracha (compactado em muitos distribuidores):
Rubber is a program whose purpose is to handle all tasks related to the compilation of LaTeX documents. This includes compiling the document itself, of course, enough times so that all references are defined, and running BibTeX to manage bibliographic references. Automatic execution of dvips to produce PostScript documents is also included, as well as usage of pdfLaTeX to produce PDF documents.
O Rubber ocultará toda a saída (que é redirecionada para um arquivo .log) e exibirá somente as mensagens de erro relevantes quando invocado.
É tudo sobre o buffer de saída.
O problema que você está enfrentando não está no modo grep , mas como pipe faz. Ou, mais precisamente, como pdflatex permite que o pipe funcione. Ele usa o pipe da maneira padrão - isso significa que a saída que passa pelo pipe é buffered . É o programa pdflatex que decide se sua própria saída pode ou não ser armazenada em buffer. Não tenho certeza, mas acho que não há opções padrão que você possa usar no lado deste programa para dizer a ele para não armazenar em buffer sua saída redirecionada.
No entanto, você pode usar o programa stdbuf que atua como um tipo de wrapper em torno do seu comando ( pdflatex ) e ajusta o caractere do fluxo de saída de acordo com suas necessidades:
stdbuf -oL pdflatex -file-line-error ... | grep ...
ou
stdbuf -o0 pdflatex -file-line-error ... | grep ...
(escapa e escaneia os comandos para facilitar a leitura). Veja man stdbuf para detalhes.
Além disso, você pode enganar pdflatex (sem causar danos) para não armazenar em buffer sua saída fazendo com que "pense" que a saída não é redirecionada. O programa script pode ser usado para isso:
script -c 'pdflatex -file-line-error ... ' | grep ...
Note que este precisa de aspas em todo o comando pdflatex ... .
É um problema de buffer de fluxo de E / S padrão, como já foi apontado por rozcietrzewiacz.
Para um artigo bem detalhado sobre essa questão, veja:
Aqui está um pequeno caso de teste que filtra avisos do pdflatex (em vez de erros) para o ftxtug Vim TeX-PDF. Eu estou usando o comando script no Mac OS X para fazer a saída de pdflatex line-buffered. Da mesma forma, o modo de buffer de linha de saída de grep também é ativado (embora não deva ser necessário aqui).

Talvez tente tee ing stdout para o terminal de controle /dev/tty antes de stdout passar para o comando final grep ?
# example using ls instead of pdflatex in Bash
# all of stdout goes to the controlling terminal before grep
ls -ld / errorfile 2>&1 | tee /dev/tty | grep error
# only grep-filterd stdout goes to the controlling terminal before the final grep
ls -ld / errorfile 2>&1 | tee >(grep --line-buffered error > /dev/tty) |
