  19 Sometimes you can&#039;t send a program some characters association (e.g. Ctrl+S) because the bash window intercepts then. In order to the program to work correctly, you must remove this character association from bash. Here is an example:
  20 </p>
  21 <pre class="code bash"><span class="co0"># see escape characters association</span>
  22 $ <span class="kw2">stty</span> <span class="re5">-a</span>
  23 <span class="co0"># shows ... ; stop = ^S; ...</span>
  24 <span class="co0"># let's associate stop to Ctrl+Q</span>
  25 $ <span class="kw2">stty</span> stop ^Q
  26 <span class="co0"># now CTRL-S will be passed to the program running inside the bash</span></pre>

  40 The file ~/.bashrc is read and executed every time you open bash. So if you want that a configuration change (like stty) to be true the next time you open bash, you must append it to the ~/.bashrc. Here is an example code:
  41 </p>
  42 <pre class="code bash"><span class="co0"># append to ~/.bashrc</span>
  43 $ <span class="kw3">echo</span> <span class="st_h">'stty stop ^Q'</span> <span class="sy0">&gt;&gt;</span> ~<span class="sy0">/</span>.bashrc</pre>

  57 If order to use the same configuration file on many PCs (e.g. your work and you home), you can include your main file on the ~/.bashrc of those PCs. Example:
  58 </p>
  59 <pre class="code bash"><span class="co0"># append to ~/.bashrc (do this on each PC)</span>
  60 $ <span class="kw3">echo</span> <span class="st_h">'source /path/to/your/main/configuration/file/.bashrc'</span> <span class="sy0">&gt;&gt;</span> ~<span class="sy0">/</span>.bashrc</pre>
