Hi,

I want to rename all the files (more than 100 files) in a fodler to another folder with date&time stamp.

foe eg,

file1.dat
file2.dat
file3.dat
..

to be renamed as

file1100629_16_30_15.txt (yy-mon-dd_hh_mi_ss)
file1100629_16_30_16.txt
..
so on

Thanks & Regards,

You do know about cp -p - preserves file times and permissions?

filetime()
{
perl -e '
      $mtime = (stat("$ARGV[0]"))[9];

      # time structure into variables

      ($sec,$min,$hr,$day,$mon,$yr,$wday,@dntcare) = localtime($mtime);
      $yr = ($yr>=70) ? $yr+1900 : $yr+2000;
      $yr=$yr%100;
      $mon+=1;

      printf ("%d%02d%02d-%02d-%02d-%02d", $yr,$mon,$day,$hr,$min, sec); ' "$1"
}
cd /old/path
for fname in *
do
   newname=${fname%%.*}$(filetime $fname).txt
   mv $fname /another/path/${newname}
done
