From Beginning Appears to be always on about node-tail

[dbrown2642]

Also on Mac, using your terminal command worked for me. I was originally adding lines through VSCode which it appears must save files in a way that makes node think each line is being generated again. Apologies for the confusion.

That shouldn't be the case.
I manually rested the library (adding a new line to an existing file) and I cannot replicate what you suggest.

Which version of tail are you using?

[dbrown2642]

Currently on version 1.2.4.
Running the code I attached, if I create the a single line in fileToTail.txt with the text "first line", the terminal will output:

first line

If I then create a second line with the text "second line", the terminal with now read:

first line
first line
second line

Attempting this in debug mode, if I create a third line with the text "third line" and create a breakpoint inside my tail.on("line") function, I find that my function executes three times, with the data object as each of the lines (first "first line", then "second line", then "third line").

Which OS are you using?
Which nodejs version?
How do you append the line to the file?

To give you my test setup:
-OSX

• nodejs 10.4.0 (but I tried also on a much older release)
  I appended text with:
  echo "new line" >> fileToTail.txt

Glad to hear it's working as expected.
I'll close the issue.
