Question

I need to know if we have any command on UNIX such that:
It gives me all the files which got updated after time t in the current directory

Answer 1

You can use the find command for this.

Touch a file with your specific date and then use that file with the -newer parameter of find.

# To find all files modifed on 10th of Dec:

touch -t 12100000 foo
#        MMDDhhmm

find ./ -type f -maxdepth 1 -newer foo
