Merging lines based on occurances of a particular character in a file

Hi,

Is there any way to merge two lines based on specific occurance of a character in a file.

I am having a flat file which contains multiple records.
Each row in the file should contain specified number of delimiter.
For a particular row , if the delimiter count is not matched with the specified count, then then next row should be merged with the previous row. Again the same check has to be done.

The script should accept number of occurances of a particular delimiter as the parameter.

For Example if the number of occurances of comma in every line is 5 in a flat file

Sample Input

1,2,3,
4,5,6
a,b,c,d,e,f
10,20,30
,40,50,60
11,22
,33
,44,
55,
66

Output (Each row should contain 5 commas)

1,2,3,4,5,6
a,b,c,d,e,f
10,20,30,40,50,60
11,22,33,44,55,66

XkbFreeGeomOverlayKeys(3)					   XKB FUNCTIONS					 XkbFreeGeomOverlayKeys(3)

NAME
XkbFreeGeomOverlayKeys - Free keys in an overlay row SYNOPSIS
void XkbFreeGeomOverlayKeys ( row, first, count, free_all ) XkbRowPtr row; int first; int count; Bool free_all; ARGUMENTS
- row row in which keys should be freed - first first key to be freed - count number of keys to be freed - free_all True => all keys are freed 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. If free_all is True, all keys are freed regardless of the value of first and count. Otherwise, the number of keys specified by count are freed, beginning with the key specified by first in the specified row. RETURN VALUES
Success The XkbFreeGeomOverlayKeys function returns Success if there are no allocation or argument errors. DIAGNOSTICS
BadAlloc Unable to allocate storage BadValue An argument is out of range X Version 11 libX11 1.2.1 XkbFreeGeomOverlayKeys(3)
