[SOLVED] add time stamps to files

VickIsSlick · 12-14-2010, 07:12 PM

Currently I am using the following command to copy and add date and time stamp to files.
cp /home/work/file.grn /home/xfer/rename_`date +%Y%m%d%H%M%S'.grn.

If I have five files for ex: file_1.grn, file_2.grn,file_3.grn ...
can I copy those five files to a different directory and with a different file name and with date time stamp to it.

The output filenames should be rename_1_yyyymmddhhmmss.grn,rename_2_yyyymmddhhmmss.grn,rename_3_yyyymmddhhmmss.grn ...

Any inputs will be appreciated.
Thanks
Vicky

hi Vicky, just an idea. if you want to copy to a lot of files to a different directory and different filename also. you might need to do a script to accomplish this. but not really sure whether it can be done using a single command line.
hope experts around here can give you more advise,

@OP, if this is a recurrent task then, as Vicky stated, a script would be the way to go. If you care to post the input file structure and output desired we'll have a better chance of providing a solution to your query.

Code:

for i in file_*.grn
do
  new=$(echo $i|sed -r 's/file_([0-9]+).*/rename_\1/')$(date +%Y%m%d%H%M%S).gen
  cp $i path/to/dir/$new
done

Something like that should work; untested.

Cheers,
Tink
