I want to search all the files in a directory for a string and save the
results in an Array. So far, the best solution I can come up with is
using system(“grep … > resultsFile”), then opening resultsFile and
doing readlines(). There’s a better way, isn’t there?

Yep: Dir["/some/foo/directory/*"]
See the docs for Dir#glob

untested
found = {}
Dir[“/foo/*”].each {|f| found[f] = File.open(f) {|io|
io.grep(/your_string/)} }
This should give you a hash with file names as keys and match lines as
values.
