recover file contents
 

Hello,

rhel5

used below command on log file to clear it contents

> filename.log

now want to recover those contents

is it possible if yes how ..

you will not get usable answer, because:
you need to ask RH support first
probably you have a backup
probably there is no way to do that, because the content is already overwritten,
probably testdisk, ddrescue or a similar tool can help you, but probably not
