Or, using the perl solution

Code:
FIRSTLINE=`perl -pi.bk -e 'print( STDOUT $_ ) and $_= "" if ($. == 1);' bigfatfile`

Then, you'll get the value of the first line stored in the FIRSTLINE variable, and the line will be deleted from "bigfatfile". Alternatively, just redirect to another file...
Code:
perl -pi.bk -e 'print( STDOUT $_ ) and $_= "" if ($. == 1);' bigfatfile > first_line

Cheers
