Hello JSKOBS,

Since you haven't mentioned your os, could you please try following command let us know if this helps.

stat filename

EDIT: Following command may help you to get the complete time format as you require.

ls -ltr --time-style="full-iso"
OR
ls -ltr --time-style="long-iso"

Thanks,
R. Singh

Hello JSKOBS,

Not sure if you have tried command which I have given in post#2, it will give following output as per your requirement.
Kindly let me know if you have tried that command and it doesn't meet your requirement.

ls -ltr --time-style="long-iso"
-rw-r--r-- 1 singh4     singh4       33 2014-12-12 03:59 test1
drwxrwxr-x 2 singh4     singh4  240 2014-12-12 03:59 test2
drwxr-xr-x 2 singh4     singh4  160 2014-12-12 03:59 test3

Thanks,

actually im checking the timestamp of the file in SFTP server. During sftp, im writing the o/p to a text file. from the text file, im trying to check the file timestamp.
ls -ltr --time-style="long-iso" command is not working in sftp server.

Thankyou.

Using GNU date:

$ date --date="Dec 11" +"%Y-%m-%d"
2014-12-11

Hello JSKOBS,

Sorry for confusion, as you have mentioned as you need the time format in ls command so only I tried to give that solution, you can convert it by following command but not tested though during sftp , give a try and let us know if that helps.

date -d"Dec 11" +"%Y-%m-%d"
OR
date -d"Dec 11" +"%Y/%m/%d"

Thanks,
R. Singh
