To edit each file that contains 201107: $ 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 /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.)
