Perhaps it’s because you tried to nest single quotes within single
quotes. You need to use something else instead, like double quotes or
%q (equivalent to '):

cat file.html | ruby -pe ‘gsub(/(<td.agenda./td>)/, %q())’

I suspect it’s a quoting issue. I would try:

ruby -pe ‘gsub(/(<td.agenda./td>)/, %q{})’

Note that you also double those \ depending on your shell (e.g. \1
instead of just \1 )
