SublimePorte Posted May 11, 2010 Share Posted May 11, 2010 I am trying to read a file line by line from the end.According to docs:[optional] The line number to read. The first line of a text file is line 1 (not zero), last line is -1.One would assume that -2 would be the second last line and so on, yet it doesn't appear to be the case.Any way to read a file line by line from the end?

SublimePorte Posted May 11, 2010 Author Share Posted May 11, 2010 Ahh should've checked the udf's for a function to countlines. Thanks. Link to comment Share on other sites More sharing options...
