Changing Key User Files

• The system wide startup file is /etc/rc.local
  
  
• Most startup scripts run from /etc/rc.d/init.d/ use chkconfig to control them
  
  
• The user specific file is $HOME/.bash_profile
  
  
• System wide environment and startup programs are in /etc/profile
  
  
• System wide functions and aliases go in /etc/bashrc
  
  
• To change your startup shell edit /etc/passwd. The last entry is the shell.

The sytem wide aliases are in /etc/bashrc
The user specific aliases are in @HOME/.bashrc

The files are self explanitory. To create a lsl command which is equivilent to ls -aFl|less, add

alias
lsl='ls -aFl|less'

Now you can run lsl instead of ls -aFl | less
