To edit each file that contains 201107:
=20 $ vi ` grep -l 201107 {files to be searched} `
That won't pre-position within the files, but since it's a single
invocation of vi, with each subsequent file being loaded by :n, a
search pattern will persist (unless/until you replace it by entering
a different search pattern). At the top of the first file, you enter
=20 /201107
to find the first instance, "n" to find the second, etc. After :n
-- at the top of the second file -- "n" alone will find the first
instance.
OTOH if you want to bring up an xterm containing _the results of
the grep_ you can pipe it into the attached script. There is no
manpage, but the comments and the (straightforward) parameter
decoding should provide a start. (There are a few "magic numbers",
which ideally should be tweaked for your X11 installation's font
dimensions, but nothing horrible will happen if they are slightly
off.)
-----
get your grep script to return the line number of the item to be changed
and=20
then use vi -c<linenumber> filename .... this is preposition you on the
line
containing the grepped target.
