title: What is the bash equivalent equivalent to the C shell `~/.cshrc` file?
body: <p>For several years I have grown accustomed to using the Bash Unix shell, which is the default on Macbooks. </p>
  
  <p>I am running through some old software which directs me to make changes to the C-shell <code>~/.cshrc</code> file, which is read each time you begin a new csh or tcsh shell.</p>
  
  <p>I'm not entirely sure what the Bash equivalent to this. I imagine I could simply <code>cd</code> to the appropriate subdirectory and make changes there. </p>
  
  <p>Apologies for the ignorance. </p>
