test to compare timestamp on files

[KapilRaj]

Folks,

Is there any option to "test" command , which will find out , one of the input files is older to the other.

Eg: test (@$$ option which i am not aware) file1 file2

If RC is 1 file2 is older than file1 or else vice-versa

I am stuck in between a script. If any one could help me out.

Please explain to me with an example...

Thanks

How about-

if [ /file1 -ot /file2 ] ; then
echo "file1 older than file2"
else
echo "file1 not older than file2"
fi

Do a man test to find out more. Their is a "-nt" option available to test for newer.

From the ksh man page:

File1 -nt File2 - True, if File1 exists and is newer than File2.

File1 -ot File2 - True, if File1 exists and is older than File2.

if [ -nt $file1 ]
then
echo $file1 is younger
else
echo $file1 does not exist
fi
