What is the role played by /dev/null here? I tried the command with 
/dev/null and without. The behavior was the same.

[root at marvin ~]# su - veejay -s /bin/sh -c "tar cvf 
/home/veejay/test.tar /home/veejay/test" < /dev/null &> 
/home/veejay/test.log &

[root at marvin ~]# ll /home/veejay/test.*

[root at marvin ~]# su - veejay -s /bin/sh -c "tar cvf

[root at marvin ~]# ll /home/veejay/test.*
