Captured some records in the files ?

Hi,

Actually I have one files with 490938351 bytes for filesize and 3747621 lines.

So, my problem is how to captured some records of files at line 33545 until 33600 and 33545 until ends of files.

Previously, I tried used tail command but the result is totally out :

Code:

cat original_files.txt |tail -3714077 > output1.txt

I did not know what's going on, might be the data is very bigs and more than 20 kybtes....

from man tail "...Tails relative to end-of-file are stored in a 20-Kbyte buffer",

So, anyone could help me how to capture the records ?

sed to the rescue...

Try these commands...

PHP Code:


		
			
 cat original_files.txt | sed -n 33545,33600p > output1.txt

cat original_files.txt | sed -n 33545,3747621p > output2.txt

Good luck.

(forgot the -n flag to supress default output)
