Hi all,
when deleting vectors in v.digit, they are just marked as deleted
(following the v.clean manual entry). v.clean would throw them
away later. But if I decide that I need them back, how to *undelete*
the vector lines? I could not find such an entry in v.digit etc.
Thank you
Markus Neteler
Markus,
To undelete lines (or areas) that have been deleted but NOT
v.clean(ed), do the following:
cd $LOCATION/dig_att
vi TheVectorFile.InQuestion
(replace all of the lower case characters (either a's or l's) along
the left margin with the UPPER case equivalent... (eg. A or L).. The
global replace option in VI works great for this...
If memory serves me thats all you need to do..... 
Have a good day,
brian culpepper

This takes care of _half_ the problem, the attributes. To recover the
actual geometry, you must run v.out.ascii to produce an ASCII version of
the file. Edit the file the same way that Brian notes below, i.e., change
lower case "a" and "l" to upper case. Use v.in.ascii to re-import the
file. Run v.support when you are finished. Note that this restores _all_
deleted features.
