I came up with a very clumsy one, but easily to see what's going on,
anyway, it seems work.

$ echo "BI -o\" gif_output_file" | sed  -e 's/.* \(\-o\)\([\"]*\)
\(.*\)/\\texbf{\1} \\textit{\2} \\textit{\3}/g; s/\_/\\_/g ; s/
\\textit{}//g '
\texbf{-o} \textit{"} \textit{gif\_output\_file}

echo "BI -o gif_output_file" | sed  -e 's/.* \(\-o\)\([\"]*\)
\(.*\)/\\texbf{\1} \\textit{\2} \\textit{\3}/g; s/\_/\\_/g ; s/
\\textit{}//g '
\texbf{-o} \textit{gif\_output\_file}


You are welcome.
