Appending data to a file in a cron job
Hi,

I have tried these methods but the data from the "original" file does not appened to the "duplicate" file.

1) 30 10 * * * cp /htdocs/original /htdocs/duplicate
As expected, this command overwrites the "duplicate" file.

2) 30 10 * * * cp /htdocs/original >> /htdocs/duplicate
No changes in the "duplicate" file.

3) 30 10 * * * /htdocs/original >> /htdocs/duplicate
No changes in the "duplicate" file.

4) 30 10 * * * cp /htdocs/original > htdocs/duplicate
This command deletes all data in the "duplicate" file.

5) 30 10 * * * /htdocs/original > htdocs/duplicate
This command deletes all data in the "duplicate" file.

Can someone please help me out with this. Thanks a lot.
