find . -type f -name '*xyz*' -newer start.file ! -newer end.file -exec ls -ltr {} \+
The above cmd is not giving files accord. to timestamp , so doesn't give required o/p

find . -type f -name '*xyz*' -newer start.file ! -newer end.file -print | xargs ls -ltr

The above cmd is giving files accord. to timestamp , this is working as required...

Also the below cmd is working.......
ls -ltr `find . -type f -name '*xyz*' -newer start.file ! -newer end.file -print `

Thanks for your inputs...
