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.)
-
get your grep script to return the line number of the item to be changed
and
then use vi -clinenumber filename this is preposition you on the
line
containing the grepped target.

scrpt help neded...
Y'all, Not sure where it was the calendar or something else that suddenly made my tying go South. maybe both. --oh, yes, i still need to buy a new clicky kybd. but that won't help with the script i need. back hen i worked from cray reseach in WI, a shell /bin/sh wizard cooked up what i wanted in minutes. i have lost in in the 20+ years so maybe some shell or perl guru can help me. I'm looking for a script that takes on arg and lets me vi/vim into the r esults. Let's say that I'm looking for the string 201107 in a slew of files. the script find it with grep---not grep -w, just grep. collect es the filenames and lines (grep -n) and saves then temporarily, then points vim or vi at each file+linenumbr and execs it for me. the fewer keystrokes, the better. can anybody help me? tia, gary -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix Journey Toward the Dawn, E-Book: http://www.thought.org The 8.51a release of Jottings: http://jottings.thought.org ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
