Empty a file

[hkhan12]

I have a trace file, lets say trace0.dat

I need to make this file empty every Monday, 9:00 am.

I have created a file called dlttrace as follows and saved it:
> trace0.dat

Now I put this file dlttrace in crontab as follows:

0 9 * * 1 /trace/dlttrace >> dlttrace.out 2>&1

On Monday 9:00 am, this script did run and my output file dlttrace.out generated but its empty and trace0.dat file is NOT empty, still it has data which I wanted to remove it from the file.

Any idea or help would be highly appreciated.

Thank you,

Hasham

Replace this:
> trace0.dat
By something like this:
> /path/to/dir/trace0.dat

Hope This Helps, PH.

Set the FULL path for trace0.dat in the script:

> /topdir/nextdir/otherdir/trace0.dat
