After more than 375 posts, I am very disappointed that you still don't have any idea how to write a simple for or while loop using a standard shell! And, the title of this thread doesn't give any indication of what you are trying to do.

You were also very skimpy with details about whether or not all of your directories will actually contain a log file for the desired hostname, how the variables hostname, fdrdate, and greptime are set, nor where the log directory is located.

Maybe the following will give you a starting point:

Code:

#!/bin/ksh
#set -xv
basedir="/path/of/log"
fdrdate_new=${1:-fdrdate_new default value}
greptime=${2:-greptime default value}
hostname=${1:-default hostname}
looking=1
cd "$basedir"
ls -td * | while [ "$looking" ] && read fn
do
	if [ ! -d "$fn" ]
	then	continue
	fi
	if grep "$greptime.*exit" "$fn/Prod.$hostname.log" | grep "$fdrdate_new"
	then	echo "Match found in file: $fn/Prod.$hostname.log"
		looking=
	else	echo "No match found in file: $fn/Prod.$hostname.log"
	fi
done
if [ "$looking" ]
then	echo "No match found."
	exit 1
fi

NAME

       line - Reads one line from standard input

SYNOPSIS

       line

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       line:  XCU5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

OPTIONS

       None

DESCRIPTION

       The  line  command  copies one line, up to and including a newline, from standard input and writes it to standard output.  Use this command
       within a shell command file to read from your terminal.	The line command always writes at least a newline character.

NOTES

       The line utility has no internationalization features and is marked LEGACY in XCU Issue 5. Use the read utility instead.

EXIT STATUS

       Success.  End-of-File.

EXAMPLES

       To read a line from the keyboard and append it to a file, enter: echo 'Enter comments for the log:' echo ': c' line >>log

       This shell procedure displays the message: Enter comments for the log:

       It then reads a line of text from the keyboard and adds it to the end of the file log.  The echo  ':  c'  command  displays  a	:  (colon)
       prompt.	See the echo command for information about the c escape sequence.
