Is there any simple tool which allows to extend all lines in .shp to another .shp?

To clarify, I do have river.shp and sections.shp on the river. I'd like to produce buffer from river, extend lines in section.shp to the buffer or clip lines if neccesarly (may happend in some cases).

I thought it would be a simple operation, however can't find any tool which would extend my lines. Do I miss something? Any suggestions?

Thanks
T.


Question: What does it mean to interpret the Bible literally?
Answer: A literal interpretation is often in contrast to a symbolic or metaphoric interpretation.  A literal interpretation accepts the text as written to be historical and factual, while a metaphorical interpretation will often reject the historicity of a particular account and accept the moral or principle of the account.

This does not mean that literal interpretations force everything to be historical, like the parables of Jesus, but it accepts narrative as historical, poetry as poetry, and prophecy as prophecy.

When the Bible says God created Adam on the sixth day, a literal interpretation accepts that as historical and factual, while a metaphoric interpretation would likely see the whole creation account as unhistorical.
