Hi,
1) Sort the file on 2nd column
2) Using SED select the range of lines using pattern
Code:
sort -k2 filename| sed -n '/05\/Jul\/2010:07:00/,/06\/Jul\/2010:08:00/p'

Hi,
You may want to use the -T <directory> option to force sort to use a scratch directory that has enough free space. By default it uses TMPDIR - usually /tmp or var/tmp.
If you need to sort the file quickly use -y option with no argument for the option. This starts sort with the maximum free memory allowed or available.
Code:
sort -y -T /dir/having/enough_free_space/ -k2 test | sed -n '/05\/Jul\/2010:07:00/,/06\/Jul\/2010:08:00/p'
