Hi Chitishri,
Code:
head -1000 abc.txt               _______this will give you the first 1000 lines
tail -1000 abc.txt                 ________this will give the last 1000 lines

so (> acd.txt) which yu added to the above command wil just create a file or override to the existed file .

note:like if you write cat file >new_file _______________here same thing happens. 

not the head command will create file.

regards,
Sanjay.
