---------- Post updated at 02:27 PM ---------- Previous update was at 02:23 AM ----------

Hi,

there is a new requirement in above script.
Apart from input filr a string is also sent as second parameter.
I have to search the filename whether that contains the passed input string or not.
Here is the script that i am using:
#! /usr/bin/ksh
stringtomatch="$2"
awk ' { FN=$NF
if(0!=index($NF,stringtomatch))
{
if ((getline < FN) > 0) {
close(FN);
print FN " exists and is readable"
} else {
print FN " does not exist"
}
}else {
print FN "does not contain string"
}
}' "$1"
Please help.TIA-Manish
