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.

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"
