Clearing file contents
Hi,

We need to clear the contents of a file. For this we tried using the commands like - '>filename' and 'cat filename > /dev/null'.

If the file size is large, the above commands will clear the file contents but the size of the file remains the same (checked using the command 'ls -l filename').

Are there any other UNIX commands which will empty the file contents?

Regards,
Raghavendra
