Regular Expressions: Marking Up a Document with sed

You are an employee at EtherCloud, a web hosting company. There has been a push to migrate all internal documentation to Latex, and it has fallen to you to convert some files. A few files in particular are oddly formatted. Using a sed script and the provided example file, mail-forwarding.txt, create a script that completes the following tasks:

• Add the following to the top of the document:

  documentclass{article}
  usepackage{hyperref}
  begin{document}

• Encase the first line in a /title{NAME} tag

• Convert all sections starting with Roman numerals to use section{NAME}; do not keep the Roman numerals (Roman numerals use the following letters: I V X L C D M

• Encase all lines starting with [root@red-hat ~]# in code blocks (begin{verbatim} and end{verbatim}; note that the ~ can be alternate text

  • There are some instances where two lines start with [root@red-hat ~]# immediately after one another; use sed's N functionality to write this portion of the script

• Any lines beginning with four spaces or a tab should be contained in code blocks; it is acceptable for each line to have its own code block tags since each line in a different setting

• Format any file names ending with .cf to use /texttt{TEXT} tags

• Change anything encased in backtics to use /texttt{TEXT} tags

• At the end of the document add end{document}; this can be done by using $ a <APPENDED TEXT>

Save the script as latex.sed and the converted file as mail-forwarding.txt.
