Question

The file is very large so I cannot store in memory. I iterate line by line as follows

for (line <- Source.fromFile(file).getLines) {
}

How can I specify that the first line should be skipped?

Answer 1

How about:

for (line <- Source.fromFile(file).getLines.drop(1)) {
  // ...
}

drop will simply advance the iterator (returned by getLines) past the specified number of elements.
