You have posted 1 single file node - not much use to anyone.

Please provide all the info a person would need to be able to help you.

Do you mean you want to fetch just the last line of a file?

If so then search the forum for  
last line of file

Did the forum search not suggest how to do it?

For me, the first hit of [Search results for 'last line of file' - Node-RED Forum](https://discourse.nodered.org/search?q=last%20line%20of%20file) is [CSV file - last line require](https://discourse.nodered.org/t/csv-file-last-line-require/11153) which appears to be be exactly what you are asking. Probably other hits there also address the issue.

Just to point out that I too found the post that Colin linked to.

I tried the suggestion which seemed most interesting  
`Or you can set the csv node to "a message per row" and feed it into a trigger node configured like "send nothing"; "extend delay"; "then send the latest msg object"`

It turns out that it won't work using the Read File node set to "a message per line" if the last character in the file is `\n` - almost universally the case, at least in Linux.
