How can I store the string value in stdout from the following Ruby code?
stdin, stdout, stderr = Open3.popen3('grep something test.txt')
I can display the value like this: stdout.gets. However trying to store the value like this: s = stdout.gets just sets s to nil. Trying to store the value like this: s = stdout stores something like "#<IO:0x1003abe10>" in s.
output = stdout.readseems to work.
