#intersect

Prints intersection of two files line by line. For comparison lines are trimmed. Empty lines are skipped. Intersection detection is done via hashset intersection, so the output is unordered.

Usage

intersect <file a> <file b>

Example

Given the file a:

a
b

And the file b:

  b
 
c

The output is:

$ intersect file_a file_b
b
