Hi Anthony/All;
Based on my previous mail I have made a few changes in the code,
Problem:
if a <Matching Tags> is found , <Repalcing strings> is placed in the
next line not in the same line. I mean there is a shift, pl have a look
and run the code with some file as:
Temp.txt:
DEAD MAN=HAPPY MAN
FOX IP=192.168.1.1
Current code when executed:
#./a.out "DEAD MAN" "00.00.00.00.00.00"
the "Temp.txt" file shows
DEAD MAN=HAPPY MAN
FOX IP=00.00.00.00.00.00
Kindly find the code!
#include <stdio.h>
int main (int argc , char **argv)
{
FILE *fp ;
int c, rep, i ;
char buf[100];
int location;
if ( argc != 3 ) {
printf ( "Usage : %s : <Matching Tags> <replace_string>\n" ,
argv[0] ) ;
exit (1);
}
if ( ( fp = fopen ( "Temp.txt" , "r+" ) ) == NULL ) {
fprintf ( stderr , "Error in opening the file\n" );
exit (1);
}
rep = 0; i = 0; location=1;
while(fgets(buf, 1000, fp)!=NULL)
{
if(strstr(buf, argv[1])!=NULL)
{
while ((c = fgetc(fp))!=EOF ) {
if (c == '=' ) {
while ( argv[2][i]!= '\0' ) {
fprintf ( fp , "%c" , argv[2][i], '\n');
i++;
}
rep = 1;
}
if ( rep );
}
location++;
}
if (location==1);
}
fclose(fp);
return 0;
}

Thanks, I sorted it out.. for some unseen character not shown in VIM
editor..
B.t way..I would like to add the functionality..some what like this..
./a.out <Matching Tags> <Replacing Strings>
as argv[1] and argv[2]..
The program take input <Matching Tags> i.e argv[1] to search for any
matching parameter in a particular line.
If it finds that <Matching Tags> preceed with "=" in the file, then that
line should be over written as
<Matching Tags>=<Replacing Strings> for all lines that matches the
<Matching tags> i.e argv[1]
Current the program you sent is writing any string passed just when it
encounters first "=" character and appends the string next to it..
Thanks for your mail..
