How to skip few lines in a file and add it into another file?

[761210]

Guys,

I am having problem adding lines from file abc to file def.
The command I tried is:
cat | tail +3 abc >> def;
The problem is tht I need to hit ENTER twice before above statement successfully executed.
Any idea why is this so? Kindly advice.

Why do you need the initial cat?

...and end with ";"? The ; is used to run consecutive commands.

ls ; ps -ef

The above command doesn't make any sense, but it will run "ls" and then "ps -ef" afterward.
