Subject: Re: get first and last line from txt file - how?

From: Thomas Preymesser [mailto:thopre@gmail.com] 
# Really?
# ....
# I did the tests with a test file with almost 8,000,000 lines.

test w zero or one line first
 
# My q&d code:
# 
# f=File.open("input")
# pos = 2
# f.seek(-pos, File::SEEK_END)
# c = f.getc
# result = ''
# while c.chr != "\n"


quick reaction:  this would sure to fail on zero-or-one-liners that do not end w a newline, no?


#   result.insert(0,c.chr)
#   pos += 1
#   f.seek(-pos, File::SEEK_END)
#   c = f.getc
# end
# f.close
