You may also find awk will do the job.  More recent options are Perl, Python
Aand Ruby.  Some of this is a matter of personal taste. sed is a good choice
for many reasons, though I have found it difficult to debug at times.

That should be "tex" rather than "lex" document, I think.  It is that
document you wish to process, and preserve in case things go wrong.

It is the -e option to take an expression.  See tutorials here:
http://www.dblab.ece.ntua.gr/~george/sed/

This ("Unix text processing") might be helpful:

On a francophone forum of Ubuntu users, one member suggest me to use Lex, a much more powerful text processing tool, to deal with it; but nobody know exactly how to do these following tasks:
