Afaik sort has no option on which line it should start or which to bypass and just print them. It would be used in conjunction with other commands. Examples:
Can someone please tell me how to sort a file, based on a particular position within the file?
I have a line sequential file that is 152 bytes per record, in which i need to sort the file based on the numeric data in positions 142-152.
I have done the "man sort" command and see the -k option... (1 Reply)
Hi,
I am going to sort a huge flat file using sort command, this file is about 36 million lines, 179 fields delimitered by Ctrl B (002). eg.
1^B198709.....
17^B200301....
3^B196511....
.....
I want this file being sorted by the first field, the result is like :
1^B198709........ (2 Replies)
Hi
IŽd like to get a few explanations about how the sort command works when cascading the options.

disksort
disksort(9F) Kernel Functions for Drivers disksort(9F)NAME
disksort - single direction elevator seek sort for buffers
SYNOPSIS
#include <sys/conf.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>
void
disksort(struct diskhd *dp, struct buf *bp);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
dp A pointer to a diskhd structure. A diskhd structure is essentially identical to head of a buffer structure (see buf(9S)). The
only defined items of interest for this structure are the av_forw and av_back structure elements which are used to maintain the
front and tail pointers of the forward linked I/O request queue.
bp A pointer to a buffer structure. Typically this is the I/O request that the driver receives in its strategy routine (see strat-
egy(9E)). The driver is responsible for initializing the b_resid structure element to a meaningful sort key value prior to calling
disksort().
DESCRIPTION
The function disksort() sorts a pointer to a buffer into a single forward linked list headed by the av_forw element of the argument *dp.
It uses a one-way elevator algorithm that sorts buffers into the queue in ascending order based upon a key value held in the argument buf-
fer structure element b_resid.
This value can either be the driver calculated cylinder number for the I/O request described by the buffer argument, or simply the absolute
logical block for the I/O request, depending on how fine grained the sort is desired to be or how applicable either quantity is to the
device in question.
The head of the linked list is found by use of the av_forw structure element of the argument *dp. The tail of the linked list is found by
use of the av_back structure element of the argument *dp. The av_forw element of the *bp argument is used by disksort() to maintain the
forward linkage. The value at the head of the list presumably indicates the currently active disk area.
CONTEXT
This function can be called from user or interrupt context.

WARNINGS
disksort() does no locking. Therefore, any locking is completely the responsibility of the caller.
