Hello,

I have the following questions regarding file permission access modes,

a) Why multiple writes are used in "/dev/shm/* rww" and "/dev/shm/filename 
www"? What difference does it make by using multiple writes instead of a single 
write?

b) What is the difference between rwk and krw? I can understand that order of 
execution is different but how is it useful?

Thanks and regards
Indhuja
