'gets' OS commands?

[woodyee]

Hi! I'm creating a little program for myself:

# Have user enter a directory in Windows (ex., C:\ or C:\Windows, etc)
# Have the user search the directory for .txt files
# Have user pick a file to read

I'm stuck at #1! Yikes! How can I get a user to input a command (like
"Dir.chdir")? Thanks!

I usually use fileutils.

Maybe Highline would be helpful for the interface, too:
