hide hides prog arguments from showing up by ps command. It is useful
especially if the arguments contains passwd.

Usages: 

basic: 
    hide -[b|e] prog args
    b: ps shows basename without path.
    e: ps shows empty field.
    default: ps shows name as executed.

alternative: 
    mv prog prog.hide : rename prog to prog.hide
    ln -s hide prog   : link prog to hide
    prog args         : run prog as normal

alternative: 
       ln -s hide prog.hide     : no change to original prog
       prog.hide -[b|e] -- args : run prog.hide instead of prog, note --

Examples: 

# /usr/local/bin/hide /bin/ps -eaf
    root  8251  8167  1 20:32:19 pts/4    0:00 /bin/ps
