python -m oneliner -ne "%5d: %s" % (NR, _) < input

# convert unix timestamp to something more human readable
date +%s | pyl -j ' => ' -line '_, datetime.datetime.fromtimestamp(int(_))'
# 1355256353 => 2012-12-11 22:05:53

# triple space a file
pyl -ne 'line + "\n"*2' < input

# double space only non-blank lines:
pyl -ne '_ if re.match("^$", _) else _+"\n"'
