Thanks a lot. That was really helpful.
But even though I changed it to below, it is replacing mutiple occurrence's. Am I missing something.
Code:
sub(ERE,rep,$2)
Using gsub(ERE,rep,2 replaces every string matched by ERE in field 2 on each line with the replacement string indicated by rep.
Using sub(ERE,rep,2 replaces the 1st string matched by ERE in field 2 on each line with the replacement string indicated by rep.
With the sample input you provided and the sample output you said you wanted, both of these do exactly what you said you wanted. You did not provide any sample input with the string test appearing two or more times in field 2 on a line where the 1st field on that line is the string 03.

Hi
for eg my file has:

Hi guys,
I like to find the Line number of Nth Occurence of a Search string in a file.
If possible, if it will land the cursor to that particualar line will be great.

Hi ,
I have an issue where I want to parse through the output from a file and I want to grab the nth occurrence of text in between two patterns preferably using awk or sed
! TICKET NBR : 1 !GSI : 102 ! 3100.2.112.1 11/06/2013 15:56:29 ! 3100.2.22.3 98 ! 3100.2.134.2... (8 Replies)
Hi,
I couldn't figure how to extract until last occurence of a character.
I have the string ./dir1/file1/abc.sh
The output should be /dir1/file1
So, the command should display the path until last occurence of "/".
Thanks. (3 Replies)

form_element - bilinear form on a single element
SYNOPSYS
The form_element class defines functions that compute a bilinear form defined between two polynomial basis on a single geometrical element.
This bilinear form is represented by a matrix.
The bilinear form is designated by a string, e.g. "mass", "grad_grad", ... indicating the form. The form depends also of the geometrical
element: triangle, square, tetrahedron (see geo_element(2)).
IMPLEMENTATION NOTE
The form_element class is managed by (see smart_pointer(2)). This class uses a pointer on a pure virtual class form_element_rep while the
effective code refers to the specific concrete derived classes: mass, grad_grad, etc.
IMPLEMENTATION
template <class T, class M>
class form_element : public smart_pointer<form_element_rep<T,M> > {
public:
// typedefs:
typedef form_element_rep<T,M> rep;
typedef smart_pointer<rep> base;
typedef typename rep::size_type size_type;
typedef typename rep::vertex_type vertex_type;
typedef typename rep::space_type space_type;
typedef typename rep::geo_type geo_type;
typedef typename rep::coordinate_type coordinate_type;
// constructors:
form_element ();
form_element (
std::string name,
const space_type& X,
const space_type& Y,
const geo_type& omega,
const quadrature_option_type& qopt);
// accessors & modifier:
void operator() (const geo_element& K, ublas::matrix<T>& m) const;
virtual bool is_symmetric () const;
// for scalar-weighted forms:
void set_weight (const field_basic<T,M>& wh) const;
bool is_weighted() const;
const field_basic<T,M>& get_weight () const;
// for banded level set method:
bool is_on_band() const;
const band_basic<T,M>& get_band() const;
void set_band (const band_basic<T,M>& bh) const;
