how to change a particular value in a file based on a pattern
how to change a particular value in a line of a file based on a pattern
eg:
source file will be like
=================
99999999999 maximum number(0)
ksuisikjjsl;;l skjss''llsl
minimum number 0000000
maximum number of golds(0)
target should be like
=================
99999999999 maximum number(1)
ksuisikjjsl;;l skjss''llsl
minimum number 0000000
maximum number of golds(1)
the pattern i searched ihere is maximum, once i find the pattern the value which is (1) needs to change to (2).
i will give command line parameters for the pattern needs to be searched and the existing value and the value which it needs to be changed.
in the above example
Pattern to search is maximum
existing value is 1
value to be replaced is 2.
Note : the open and closed braces will be there in all the lines < (1) >.

INSTR(3) MBK UTILITY FUNCTIONS INSTR(3)
NAME
instr - find an occurence of a string in a string, starting at a specified character.
ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
Paris, France.
Web : http://asim.lip6.fr/recherche/alliance/
E-mail : alliance-users@asim.lip6.fr
SYNOPSYS
#include "mut.h"
char *instr(s, find, from)
char *s, *find, from;
PARAMETERS
s Pointer to the string to be searched for the pattern
find Pointer to the string to be found, the pattern
from Character to be searched backwards before searching for the pattern
DESCRIPTION
instr searches the first occurence of the string find in the string s, starting its search at the last occurence of the from character in
the string s.
If either s or find is NULL, the function returns NULL. If from is (char)0, the pattern is searched from the begining of s.
This quite exotic behaviour is useful to search the occurence of a name in a string resulting from a flatten, when only a terminal object
name is to be taken into account.
RETURN VALUES
instr return NULL either if the pattern find is not present in the searched string s, or if one at least of these two string are NULL. If
the pattern is found, a value different from NULL is returned.
EXAMPLE
#include "mut.h"
/* check for the pattern 'ck' anywhere in the string */
#define contains_ck(name)instr(name, "ck", ' ')
/* check for the pattern 'ck' in the signal name, not instance ones */
#define isclock(ptsig) instr(getsigname(ptsig), "ck", SEPAR)
