No warning if /test-getreadcounts.sh run without required dependencies

[byanofsky]

While working on initival-xv6 project, I ran the test script /test-getreadcounts.sh. Its resulting output showed test 1 had failed.

Digging deeper, I discovered the required dependency expect was not installed on my system. Directly running the test/1.run script, I received an error that expect could not be found.

However, there was no relevant warning or error displayed when I had run /test-getreadcounts.sh.

After installing expect, the test showed as passing.

@byanofsky There is actually a warning, you need to look into the .err file for that particular test, and it will say something like: /usr/bin/env: 'expect': No such file or directory. But I agree it's not very clear. A friend of mine and I also had to spend some time figuring out what's wrong. Eventually we noticed the .err file. I mentioned the same issue in #22

The problem is that this repo does not seem to be maintained anymore.

even after installing expect, there is still a problem in my machine... it says:
expect: spawn id exp4 not open
while executing
"expect "$ ""
(file "../../tester/run-xv6-command.exp" line 25)

After installing "gawk", I can run /test-getreadcounts.sh .
Same issue in #12.
