* Changing Default permissions when creating a new directory
 
umask u=rwx,g=rwx,o=
 
* Set default group
 
newgrp groupname
 
  Remark: this command will start a nested shell. If you want to use the command in a startup script like in .bashrc, to avoid
 
  infinite loop, you should put it in an "if" expression like this:
 
  if [ `id -gn` != "object3d" ]
 
  then
 
    newgrp object3d
 
    exit
 
  fi
 
* Change default shell
 
chsh -s /bin/bash haosu
 
* I/O Redirection
 
if you want to redirect both standard out and standard error, you can use: 1>out 2>&1, where out is a filename, 1 stands for
 
STDOUT, and 2 for STDERR
