shell input files

\${HOME}/.bashrc, 
.bash_profile, 
.profile 
(ls -a /etc/skel)

• more /etc/skel/{.bash_profile, .bashrc}
  

• .basrhc: add to this file any shell settings that you want to keep: aliases, path settings, shell variables (CVSROOT, PS1), or programs that you want executed whenever you login.

•     more ~ijones/.bashrc
      source ~ijones/.bashrc 
      #notice how the prompt changes, since I
      #have a prompt set PS1 in my .bashrc.
  

• .bash\_profile:
  for login shells, should probably ``source ~/.bashrc''.
  I don't really use this file, except to run my .bashrc.
  

• from the man page 'man bash':
