With GNU-ls you can use

Code:
$ ls -l --time-style=+%s
total 9224

Need to create a script:

use stat command in this way:
Code:
stat -c %Z test.txt

and read this
Code:
man stat

@vipin kumar
If you can't use stat command try this

Code:
FILE=test.txt
if [[ ! -f $FILE ]]
then
echo $FILE not exists
else
N=$(find . ! -name . -prune -name $FILE -mtime +2|wc -l)
if [[ $N -eq 0 ]]
then
echo $FILE is updated
else
echo $FILE is older
fi
fi

If you have ksh93 available, you can also use the printf builtin to convert the date and time:

Code:
$ printf "%(%s)T\n" "Mar 27 09:17"
1364372220

This does NOT work with /usr/bin/printf, only the builtin version!

To be more precise:

Code:
$ ls -l x
-rw-r--r--. 1 hergp rzadmin 255 Mar 27 09:17 x
$ printf "%(%s)T\n" "$(ls -l x | awk '{ print $6, $7, $8 }')"

for existing file this code worked..but when i created new file say vip.txt...thn its showing file not exists instead it shud show that vip.txt is updated bcoz it has been created or modified today not 2 days back..

in short,
if sysdate=27 march 2013
and file date=25 march 2012 or older than that thn it will show not updated else updated.

You're saying that


Code:
FILE=mynewfile.txt
touch $FILE
if [[ ! -f $FILE ]]
then
echo $FILE not exists
else
N=$(find . ! -name . -prune -name $FILE -mtime +2|wc -l)
if [[ $N -eq 0 ]]
then
echo $FILE is updated
else
echo $FILE is older
fi
fi

and the result is?
Code:
mynewfile.txt not exists

It's strange... check your procedure
