I am using Putty to log on to the Linux Server and see the logs .
I used the command tail -f -n 1000 MyLog.log
It started displaying the last 1000 lines , On to the displayed content but i could the cursor to the whole displayed content , i could able to move only within the buffer content .
Please tell me is there any other option so that i could able to see the whole content (That is 1000 lines )
Thank you .
Where do i need to change the settings

This might be because of Putty, which has by default 200 lines of scrollback.
You can change this by going to
Putty - Window - Lines of scrollback.
