    Check if a file ends with newline

    (updated: )

    Table of Contents

    The following command will return 1 if the file ends with a newline, and 0 otherwise:

    tail -c1 <file> | wc -l
    

    Or as a function:

    function file_ends_with_newline() {
      [[ $(tail -c1 "$1" | wc -l) -gt 0]]
    }
