[GRASS-user] equivalent to "select by location"

Hello,
I am new to GRASS and learned to work with GIS on the ESRI product family.

For a project I need to do kind of a topological selection.

What is the equvalent to "select by location" in ArcMap?

Thank you for your help.

Can you describe what that does in more detail?
Many of us have not used Arc in years.

Tim,

When looking for a functionality in GRASS which you roughly know what
it could be called, just try to search the manual pages with your html
browser.

In this particular case a possible scheme would be:

1. As I know I'm looking for a vector functionality, I'd enter the
vector part of GRASS manual,
http://grass.itc.it/grass63/manuals/html63_user/vector.html

2. search for the "select" string on that page

3. it returns few hits, for 4 commands alltogether, out of which
v.select and v.extract sound promissing

Don't forget that you have the html manual installed localy too - eg.
on my machine it's /usr/local/grass-6.3.cvs/docs/html/index.html.

Another approach could be searching for a string in the
/usr/local/grass-6.3.cvs/docs/html/v.* with mc or grep or any other
tool you like. Might be tedious a bit, but still quicker than getting a
respond from mailinng list, usually.

...and when you look into v.select's manual there's a link to v.overlay
- another one you might find related.

Hi, not sure if I understand this well, but maybe v.edit tool=select
could serve you (grass 6.3)

Use "v.select".
