keyword locating files in shell programming files

Come back tonight, write the fourth question, just want to match IP, that regular expression is too disgusting ...

I remember writing before ... But, forget where to put ....

The author of the script test files are thrown into a directory, because the practice is too large, so a directory, all the time named directory, and each directory file name is test1.sh,test2.sh....test10.sh .... At least hundreds of of them ....

And the author wants, is one day, writes a script, the author only remembers that script inside looks like uses the ping keyword ... So the demand came out:

The code is as follows:

#!/bin/bash  
#Author: MOS  
#Script name:keyfind  
#Date & time:2012-10-09/23:56:59  
#Version: 1.0.1  
#Description:  
#  
#找打笔者脚本目录的位置下, all the general files are thrown into the array  
array= (' find/root/shellscripts/-type f ')  
# Loop through each file, use grep to filter keywords ("positional parameters"), and when filtered, print out the name for  
I in ${array[*]};d o
    grep $i &>/dev/null & & echo "$i" done
