Using tar inside a shell script

Shell Programming and Scripting

Hi,
I am using tar cvf inside a shell script to archive files.
Is there an option to surpress any prompts which come up if the desired archive name already exists ?

Thanks in Advance.
Kas.

For starters, you can leave off the -v flag; that's for verbosity.
Other than that, you should receive no prompts from tar.

You can also put in a check before tar cvf
by using find -name and check for sucess.
if it returns sucess you can delete the existing file or use different
file name instead.
