    <p>I am using a loop to read the contents of an array, which contains all of the directories and files in the directory hierarchy called 'music' (contents are strings from the previous output of 'find' command). The idea is to separate the full directory path of each array element in "directory_contents" into substrings according to genre, artist, and title. Since my music directory is sorted first by genre, then by artist, then by title, I am grabbing each relevant item using awk where the delimiter "/" shows up. For example, if the directory looks like this after using find "./Electronic/Squarepusher/My Red Hot Car.aif", I will separate "Electronic", "Squarepusher", and "My Red Hot Car", then store them each in separate arrays for genre, artist, and title. Later I will sort these data, then pipe the sorted output into another utility to print all the directory contents in a nice looking table (haven't done this yet). For now, I am just trying to view the results of the string separation with echo statements, and for the most part it seems to work. However, I can't seem to extract substrings which contain spaces, which isn't good:</p> <pre><code>--&gt;./Hip-Hop/OutKast/title1.aif&lt;-- Genre: Hip-Hop Artist: OutKast Title: title1 --&gt;./Hip-Hop/OutKast/title2.aif&lt;-- Genre: Hip-Hop Artist: OutKast Title: title2 --&gt;./Hip-Hop/OutKast/title3.aif&lt;-- Genre: Hip-Hop Artist: OutKast Title: title3 --&gt;./Jazz/John&lt;-- Genre: Jazz Artist: John Title: --&gt;Coltrane/title1.aif&lt;-- Genre: title1.aif Artist: Title: </code></pre> <p>As you can see, when the loop reads in the string "John Coltrane", it is treating the space as a delimiter, and treating everything after "John" as a different filename. I tried looking for a solution in the bash manual under the section "Arrays" as well as other posts here, but couldn't find a solution that worked for my specific problem (sorry). If anyone has ideas, they would be greatly appreciated. The problematic code appears below, in the for loop (I didn't post the whole script because it is pretty lengthy, but let me if it is needed):</p> <pre><code>#more before this... #declare variables declare -a genre_list declare -a title_list declare -a artist_list declare -a directory_contents #populate directory with contents cd $directory directory_contents=$(find . -mindepth 1 -type f) cd .. for music_file in ${directory_contents[*]}; do if [[ $DEBUG = "true" ]] ; then echo "--&gt;$music_file&lt;--" fi echo "Genre:" echo $music_file | awk -F"/" '{print $2}' echo "Artist:" echo $music_file | awk -F"/" '{print $3}' echo "Title:" echo $music_file | awk -F"/" '{print $4}' | awk -F"." '{print $1}' echo "" done </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
