I’ve been toying with ruby off/on in years. Now I’ve come across a
practical application that ruby may be of use to me.
Scenario: Two directories with many files in parallel: differences is
content, names are same.
I need to check which files have been modified.
That is, automating the $diff -q command thusly:
[/Users/admin/workarea]diff -q file1.txt file2.txt >> result.txt
[/Users/admin/workarea]diff -q file3.txt file4.txt >> result.txt
Files file1.txt and file2.txt differ
Files file3.txt and file4.txt differ
So imaging the scenario:
So essentially there’s a loop through one directory vs a parallel
Is there simple example how I could do this in (interactive/irb) Ruby?
