Ruby tail

Ruby
1

Hello,

Is there a gem or perhaps a method I am not aware of that does the
similar function of tail? Or is there a way to use tail in ruby? I
have a file that I want to process as new data is appended to the file.
This is easy enough using tail and tail has the added advantage that it
can follow a file if it is “rolled”.

TIA,
Phy

Just call out to tail

def tail(f)
tail f
end

or similar - if tail does what you want, use it

os independent, but slower on large files.

a = File.open(file).to_a
-10.upto(-1) do |i|
puts a[i]
end

need to be beautified :slight_smile:
