Shell Programming and Scripting

Hi,

I have a requirement in which I have to read mail from a unix text file and scan records having
failed records (any number > 0)

Firstly it should compare the file creation_date with sysdate
if the dates match then
do the checking for failed records

sample file i/p

Staged 0 records from <file_name> (2 failed)
Staged 0 records from <file_name> (0 failed)
Staged 0 records from <file_name> (0 failed)

09/27 12:45:46 I 0 Error Transactions
09/27 12:45:46 I 0 Error Transactions
09/27 12:45:46 I 0 Error Transactions


code:

var1=`grep -w "0 failed" <file_name>
var2=`grep -w "0 Error" <file_name>
if [[ -n $var1 || -n $var2 ]]; then
..... do something .....
else
..... do something .....
fi;


Is there any way I can do in a single command using sed
including the file date comparison with sysdate ?
