list of commands & utilities [WAS: change file names]

[Zhao Peng]

Bruce,

"type the tab key twice" worked well on my system, thank you!

I have 2 different userid on the system. One has "Display all 2430 
possibilities", another one has "Display all 2457 possibilities". Why 
are they different? (Because some commands are not available for some 
userid?)
