how to replace html-file-content ???

hi script-freaks,
i'm trying to remove the last 8 lines of an html-file and replace them by new 4 lines.

characteristics of the html-file: there exists some table-tags in the file, but the last table should be replaced by something new (e.f. a link to another homepage).

i would like to do this by script, but i'm really new in scripting.
could you please help me???

i think, this should go with "sed", but i'm not sure.

thanks a lot

Welcome to LQ.

You never gave a language so I'll assume you mean in a shell - try:
# Remove the last 4 lines
cat /path/to/file.html | tail -n $((`cat /path/to/file.html | grep -c ""`-4))
# Add 4 new ones
echo -e "line 1\nline2\nline3\line4" >> /path/to/file.html

hi david,

thanks for your comment (very good suggestion for me) !!!

meanwhile, i did it this way:

i count the lines if the html-file, remove the last 8 lines (with head) => read my new "end-of-file" from a source file (it's always the same) and add this to the cutted html-file.
