Lines wrap around incorrectly.</p> <p>By the way; for your reference; here's my <code>PS1</code> which looks like this: <a href="http://lhunath.lyndir.com/stuff/PS1.png" rel="noreferrer" title="PS1">alt text http://lhunath.lyndir.com/stuff/PS1.png</a></p> <pre><code>\[$reset$bold$green\]\u@\h\[$blue\] \W \[$red\]${?/#0/\[$green\]}\$\[$reset\] </code></pre> <p>Notice how I put all the color codes in <code>$parameters</code> to make it neater, but more importantly, because <strong>you should be using <code>tput</code> to generate them</strong>. See:</p> <p><a href="http://mywiki.wooledge.org/BashFAQ/037" rel="noreferrer"><a href="http://mywiki.wooledge.org/BashFAQ/037" rel="noreferrer">http://mywiki.wooledge.org/BashFAQ/037</a></a> -- How can I print text in various colors?</p> <p>I declare my color parameters in a utility script that gets sourced by <a href="http://lhunath.lyndir.com/stuff/.bashrc" rel="noreferrer">my <code>~/.bashrc</code></a> (and any scripts I write) which is called <a href="http://lhunath.lyndir.com/stuff/bashlib" rel="noreferrer"><code>bashlib</code></a>.</p> <p>On a final note; put your <code>PS1</code> definition in <code>~/.bashrc</code> and don't <code>export</code> it. There's absolutely no reason why you should add your <code>PS1</code> definition to the environment of any and all processes you spawn from your shell.</p>
