how to zero a file using csh - UNIX for Dummies Questions & Answers

Hi

I have always used ksh in the past, but now am using csh. To zero a file using ksh, you simply > filename. What is the command to do the same using csh?

Thanks in advance.

A common way of zero-ing a file which is portable
across most Unices and shells is

cat /dev/null > file

I'm sure there are other ways, but 'cat /dev/null > somefile' works on both.

Cheers,

Keith
