I will just explain about my requirement here briefly with sample file, I have attached also, please help....me..

Code:

1    28.25    36.42
5    28.26    36.42
10    28.23    36.43
15    28.22    36.43
20    28.2    36.42
25    28.19    36.43
0    28.25    36.42
1    28.26    36.42
5    28.23    36.43
10    28.22    36.43
15    28.2    36.42
20    28.19    36.43
25    28.25    36.42
3    28.26    36.42
5    28.23    36.43
10    28.22    36.43
15    28.2    36.42
20    28.19    36.43

consider 1st column only

here 1st station profile is 5 to 25, script has copy or cut 5 rows in a file, and to paste it in new file...

2nd profile starts from 0 to 25 script has copy or cut 6 rows in a file, and to paste it in another new file...

3rd profile starts from 3 to 20 script has copy or cut 5 rows in a file, and to paste it in another new file... till the end of file

I don't understand what a station profile is nor how a shell script is supposed to figure out what lines to ignore and what lines to copy into the new files.

Scrutinizer's awk script makes a perfectly reasonable assumption that you want to take each grouping of lines with increasing values in the 1st column into separate files. But, you say that the 1st new file should contain 5 rows while Scrutinizer's awk script will make newfile_1 contain 6 rows. You say that the 2nd new file should contain 6 rows, but Scrutinizer's awk script will make newfile_2 contain 7 rows. The only match is that you say the the 3rd new file should contain 5 rows and Scrutinizer's script will print 5 rows into newfile_3.

Please explain what logic should be used to produce the output you want AND please post the output that you believe should appear in those three files (in CODE tags).

xkballocgeomoverlayrows

XkbAllocGeomOverlayRows(3)					   XKB FUNCTIONS					XkbAllocGeomOverlayRows(3)

NAME

       XkbAllocGeomOverlayRows - Allocate rows in a overlay

SYNOPSIS

       Status XkbAllocGeomOverlayRows (XkbOverlayPtr overlay, int num_needed);

ARGUMENTS

       - overlay
	      section for which rows should be allocated

       - num_needed
	      number of new rows required

DESCRIPTION

       Xkb  provides a number of functions to allocate and free subcomponents of a keyboard geometry. Use these functions to create or modify key-
       board geometries.  Note that these functions merely allocate space for the new element(s), and it is up	to  you  to  fill  in  the  values
       explicitly  in  your  code. These allocation functions increase sz_* but never touch num_* (unless there is an allocation failure, in which
       case they reset both sz_* and num_* to zero). These functions return Success if they succeed, BadAlloc if they are  not	able  to  allocate
       space, or BadValue if a parameter is not as expected.

       XkbAllocGeomOverlayRows allocates num_needed rows and adds them to the overlay.	No initialization of the rows is done.

       To free rows in an overlay, use XkbFreeGeomOverlayRows.

DIAGNOSTICS

       BadAlloc       Unable to allocate storage

       BadValue       An argument is out of range
