Extrai informações do arquivo RTF no script ksh

Question

Temos alguns arquivos RTF contendo dados que precisamos extrair e buscamos a automação para extraí-lo:

Eu preciso procurar pela primeira ocorrência de <?for-each:APXINDTL?> e deve obter APXINDTL como variável. Por exemplo:

<?for-each:APXINDTL?>
LOBCODE=APXINDTL

Observação: as operações de extração não devem causar nenhuma alteração no arquivo RTF relevante.

A seguir, os dados parciais do arquivo RTF que são abertos por meio de um editor de texto:

Answer 1

Usando unrtf e analisando o texto resultante:

variable=$( unrtf --text file.rtf | sed -n '/^for-each/{s/^[^ ]* //p;q}' )

Com o exemplo dado, isso define o valor da variável como a string APXINDTL .

O comando sed localizará a primeira linha (somente) que começa com for-each e remove tudo até e incluindo o espaço. O resto da linha é atribuído à variável.
