I am using bash. Could someone tell me why is this:

mv file.txt file.txt_$(date +%F-%T)

...working as expected, giving me file_2017-01-05-13:46:50

while renaming multiple files with rename:

rename 's/file/file_$(date +%F-%T)/' *.txt

.. is not working as expected, giving me file_1000 4 24 27 30 46 118 127 1000date +%F-%T).txt and I want multiple renamed files with a date and time?

Use double quotes.. `rename "s/file/file_$(date +%F-%T)/" *.txt` – Avinash Raj Jan 05 '17 at 13:00
Thanks! Could you tell me how to rename all the files in a directory, not just those having 'file' word in it? – Hrvoje T Jan 05 '17 at 13:26
so you want to add date after filename in all the files, right? – Avinash Raj Jan 05 '17 at 13:27

If so then try this `rename "s/(.*)/\1_$(date +%F-%T)/" *.txt` – Avinash Raj Jan 05 '17 at 13:28
