You are conducting an investigation of fraudulent claims in an insurance company that involves complex text
searches through large numbers of documents. Which of the following tools would allow you to quickly and
efficiently search for a string within a file on the bitmap image of the target computer?
A.
Stringsearch
B.
grep
C.
dir
D.
vim
If your OS has a grep package, you could use a system call:
system(“grep meow cat_sounds.txt”)
This will return true if grep returns anything, false if it does not.
If you find yourself on a system with grep, you may find this is the “best” way because Ruby can be slow when it comes to file operations.
