+
+** Summary
+~rmsym~ is a Bash script which deletes symbolic links specified by
+positional arguments.
+
+** Versions
+| Version | Description                                                    |

+|   0.0.1 | Initial version. Does not accept or pass on arguments to ~rm~. |
+|         |                                                                |
+
+** Background
+I needed a script that would let me quickly delete only symlinks if I
+were to provide it with a mix of paths of files, directories, or
+symlinks; specifically, I want to be able to create music playlists
+that any music player can parse; most music players can recursively
+scan directories and a directory tree of symlinks would reduce the
+need to maintain multiple copies of music files on the same file
+system. However, in order to assure myself that when I prune symlinks
+that I don't delete actual files targeted by the symlinks, I need a
+program that will only delete symlinks.
+
+Bash supports testing whether a path is a symlink or not via the ~-h~
+test. For example, here is a simple Bash script that will report
+whether a symlink is present at ~$HOME/foo.txt~ or not.
+
+#+begin_example
+#!/bin/bash
+path_myfile="$HOME/foo.txt";
+if [[ -h "$path_myfile" ]]; then
+  echo "STATUS:Is a symlink:$path_myfile";
+else
+  echo "STATUS:Is not a symlink:$path_myfile";
+fi;
+#+end_example
