[Bug-tar] tar errorcode with perl

[Andreas Mürdter]

Hi,

i using a perl script to make a backup from hd to tape with following command:
@result = `tar -cvzf /dev/sto $dir 2>&1`;
if there is no tape in the streamer and I backup only a small directory
like "/etc", I get an errorcode "512".
when I backup a bigger directory "/var" I get an errorcode with "13"

i.e: no tape in the streamer.

1. @result = `tar -cvzf /dev/sto /etc; #### $? is 512 !
2. @result = `tar -cvzf /dev/sto /var; #### $? is 13 !

In 2. the errorcode should also be 512, and not 13. 

Is this a bug?

Andreas
