If I have a number of files like the following:
file1
:
123
456
789
012
file2
:
line1 922
line2 392
line3 456
line5 291
line6 201
...
file3
:
line1 111
line2 123
line3 19
line5 542
line6 456
...
What's the best way to get all of the lines in file1
which are contained in a line of both file2
and file3
?
In this example, it would be just:
456
