which isn't working

I have a large file 1.5 gb and want to sort the file.
I used the following AWK script to do the job
!x++
The script works but it is very slow and takes over an hour to do the job. I suspect this is because the file is not sorted.
Any solution to speed up the AWk script or a Perl script would... (4 Replies)

NAME
dlabad.f -
SYNOPSIS
Functions/Subroutines
subroutine dlabad (SMALL, LARGE)
DLABAD
Function/Subroutine Documentation
subroutine dlabad (double precisionSMALL, double precisionLARGE)
DLABAD
Purpose:
DLABAD takes as input the values computed by DLAMCH for underflow and
overflow, and returns the square root of each of these values if the
log of LARGE is sufficiently large. This subroutine is intended to
identify machines with a large exponent range, such as the Crays, and
redefine the underflow and overflow limits to be the square roots of
the values computed by DLAMCH. This subroutine is needed because
DLAMCH does not compensate for poor arithmetic in the upper half of
the exponent range, as is found on a Cray.
Parameters:
SMALL
SMALL is DOUBLE PRECISION
On entry, the underflow threshold as computed by DLAMCH.
On exit, if LOG10(LARGE) is sufficiently large, the square
root of SMALL, otherwise unchanged.
LARGE
LARGE is DOUBLE PRECISION
On entry, the overflow threshold as computed by DLAMCH.
On exit, if LOG10(LARGE) is sufficiently large, the square
root of LARGE, otherwise unchanged.
