| Sorry I have posted this before but I have a slight change in the
question.
I have an html file.The entire script is in one line only. The
following is the script.
<table><tbody><tr><td class="r">Chapter
1: ................................................. </td></tr></
tbody></table><p Hare Krishna ......................</p> <p Hare
Rama ......................</p>
where .............. is a variable text
In the above script I want to delete the text
<table><tbody><tr><td class="r">Chapter
1: ................................................. </td></tr></
tbody></table>
where ........ represents variable content.
I have 100 files with names 1.htm to 100.htm
How can i do this using unix commands rather than selecting the text
and deleting.
Thanks
Santhosh

Depending on whether not "<table>" or "</table>" can occur multiple times on a
line, this may be all you need:
for file in *.htm
do
sed 's:<table>.*</table>::' "$file" > tmp &&
mv tmp "$file"
done

Use all of the unique text you mentioned and replace the chain of periods with ".*":
sed 's:<table><tbody><tr><td class="r">Chapter 1:.*</td></tr></tbody></table>::'
If the text on either side of the ".*" can appear elsewhere on the same line,
then it's a harder problem that needs a different approach.
