Im not sure if this code is fast enough but it would find first occurance of the desired string and its a generic one

Code:

nawk -v occ="1" '$0~/mystring/{i++} i==occ{printf "occurance=%-6d, 
line=%-s\n",NR,$0;exit}' infile

use normal awk if you dont use solaris.

head -1 will works just as grep since it waits for grep to finish to stop the process. The -l only shows the file name where the first match is and it stops.....the problem is that I need the output with the data.
