Code:
# awk ' $1 ~ /^[0-9]/' file
 1      32.3kB  65.5GB  65.5GB  primary  ext3         boot
 2      65.5GB  67.7GB  2147MB  primary  linux-swap
 3      67.7GB  500GB   432GB   primary  ext3
#

Code:
# cat file
Model: ATA WDC WD5000AAKS-0 (scsi)
Disk /dev/sdb: 500GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start   End     Size    Type     File system  Flags
 1      32.3kB  65.5GB  65.5GB  primary  ext3         boot
 2      65.5GB  67.7GB  2147MB  primary  linux-swap
 3      67.7GB  500GB   432GB   primary  ext3

Information: Don't forget to update /etc/fstab, if necessary.
#

if output came from another command just pipe it to awk

Edit: or use grep:
Code:
# grep '^.[0-9]' file
 1      32.3kB  65.5GB  65.5GB  primary  ext3         boot
 2      65.5GB  67.7GB  2147MB  primary  linux-swap
 3      67.7GB  500GB   432GB   primary  ext3
#

I forgot about sed:

Code:
$ sed -n '/^.[0-9]/p' file
 1      32.3kB  65.5GB  65.5GB  primary  ext3         boot
 2      65.5GB  67.7GB  2147MB  primary  linux-swap
 3      67.7GB  500GB   432GB   primary  ext3
$

Kind regards,

XmTextFieldCut(3X)														XmTextFieldCut(3X)

NAME

       XmTextFieldCut - A TextField function that copies the primary selection to the clipboard and deletes the selected text

SYNOPSIS

       #include <Xm/TextF.h>

       Boolean XmTextFieldCut (widget, time)
	       Widget widget;
	       Time time;

DESCRIPTION

       XmTextFieldCut  copies  the  primary selected text to the clipboard and then deletes the primary selected text. This routine calls the wid-
       get's XmNvalueChangedCallback and verification callbacks, either XmNmodifyVerifyCallback or XmNmodifyVerifyCallbackWcs, or both.   If  both
       verification callback lists are registered, the procedures of the XmNmodifyVerifyCallback list are executed first and the resulting data is
       passed to the XmNmodifyVerifyCallbackWcs callbacks.  Specifies the TextField widget ID.	Specifies the time at which the selection value is
       to be modified.
	This should be the time of the event which triggered this request.

       For a complete definition of TextField and its associated resources, see XmTextField(3X).

RETURN VALUE

       This function returns False if the primary selection is NULL, if the widget doesn't own the primary selection, or if the function is unable
       to gain ownership of the clipboard selection.  Otherwise, it returns True.
