| <h4 class="subsection">33.1.3 Modifiers</h4> |
| |
| <p>After the optional word designator, you can add a sequence of one or more |
| of the following modifiers, each preceded by a ‘<samp><span class="samp">:</span></samp>’. |
| |
| <dl> |
| <dt><code>h</code><dd>Remove a trailing pathname component, leaving only the head. |
| |
| <br><dt><code>t</code><dd>Remove all leading pathname components, leaving the tail. |
| |
| <br><dt><code>r</code><dd>Remove a trailing suffix of the form ‘<samp><span class="samp">.</span><var>suffix</var></samp>’, leaving |
| the basename. |
| |
| <br><dt><code>e</code><dd>Remove all but the trailing suffix. |
| |
| <br><dt><code>p</code><dd>Print the new command but do not execute it. |
| |
| <br><dt><code>s/</code><var>old</var><code>/</code><var>new</var><code>/</code><dd>Substitute <var>new</var> for the first occurrence of <var>old</var> in the |
| event line. Any delimiter may be used in place of ‘<samp><span class="samp">/</span></samp>’. |
| The delimiter may be quoted in <var>old</var> and <var>new</var> |
| with a single backslash. If ‘<samp><span class="samp">&</span></samp>’ appears in <var>new</var>, |
| it is replaced by <var>old</var>. A single backslash will quote |
| the ‘<samp><span class="samp">&</span></samp>’. The final delimiter is optional if it is the last |
| character on the input line. |
| |
| <br><dt><code>&</code><dd>Repeat the previous substitution. |
| |
| <br><dt><code>g</code><dt><code>a</code><dd>Cause changes to be applied over the entire event line. Used in |
| conjunction with ‘<samp><span class="samp">s</span></samp>’, as in <code>gs/</code><var>old</var><code>/</code><var>new</var><code>/</code>, |
| or with ‘<samp><span class="samp">&</span></samp>’. |
| |
| <br><dt><code>G</code><dd>Apply the following ‘<samp><span class="samp">s</span></samp>’ modifier once to each word in the event. |
