Default blocking factor

[Didier Rox]

Is there a way to change the default blocking factor that tar command is using (HP-UX 11.00)?

I do not want to use -b option. I want to change the default value to another one.

Is the default value coded in a file, kernel, binary, ...?

Many thanks,
Didier

The default value will be recorded in the tar binary.

You'll have to obtain the source of tar, amend the default value and compile it. GNU tar source is available here:
