Search and Edit Files with Certain Text

Here's a quick way to edit all files whose contents contain a given string:

files=""; for i in `find . -type f -print`; do files="$files `grep -l <text> $i`"; done; vi $files

1. For all file names in the current directory, including those in subdirectories, assign each in turn to the variable i.
   

   for i in `find . -type f -print`;

2. For each of the files we found, run the grep command to search the file provided by the $i variable.
   

   do files="$files `grep -l <string> $i`";

3. Edit the found files with the vi editor.

   vi $files

   Move back and forth between files using:

   :n    -- move to the next file
   :rew  -- move back 
   :e #3 -- edit the third file in buffer
   :ar   -- list files status
