Unix Sed to get lines from a last occurance of a given word

I want to get the lines from a file from the line which contains the last occurance of a given word.

Ex:

True, there have been some
changes in the plot. In the original,
Kane tried to buy high political
office for himself. In the new version,
he just puts politicians on his payroll.

If I give "In" then I need

office for himself. In the new version,
he just puts politicians on his payroll.

This should work:

As a one-liner:

patt=In
sed -nr "/$patt/!b;:a;\$!N;/\n.*$patt/{h;s/\n[^\n]*\$//;g;s/^.*\n//};\$!ba;p" inputfile

If your sed requires -e:

patt=In
sed -nr -e "/$patt/!b" -e ":a" -e "\$!N" -e "/\n.*$patt/{h" -e "s/\n[^\n]*\$//" -e "g" -e "s/^.*\n//}" -e "\$!ba" -e "p" inputfile

On separate lines:

patt=In
sed -nr "
    /$patt/!b
    :a
    \$!N
    /\n.*$patt/{
    h
    s/\n[^\n]*\$//
    g
    s/^.*\n//
    }
    \$!ba
    p' inputfile

Try:

grep 'yourWord' yourFile.txt | tail -n1

Or with sed:

sed -n '/yourWord/{$p}' yourFile.txt

$ word="In"
$ awk -vw="$word" '{s=s$0}END{ m=split(s,str,w); print w str[m]}' file
In the new version, he just puts politicians on his payroll.

I don't understand why there is "office for himself." though.
