    <p>I am looking for a way to split a string in bash over a delimiter string, and place the parts in an array.</p> <p>Simple case:</p> <pre><code>#!/bin/bash b="aaaaa/bbbbb/ddd/ffffff" echo "simple string: $b" IFS='/' b_split=($b) echo ; echo "split" for i in ${b_split[@]} do echo "------ new part ------" echo "$i" done </code></pre> <p>Gives output </p> <pre><code>simple string: aaaaa/bbbbb/ddd/ffffff split ------ new part ------ aaaaa ------ new part ------ bbbbb ------ new part ------ ddd ------ new part ------ ffffff </code></pre> <p>More complex case:</p> <pre><code>#!/bin/bash c=$(echo "AA=A"; echo "B=BB"; echo "======="; echo "C==CC"; echo "DD=D"; echo "======="; echo "EEE"; echo "FF";) echo "more complex string" echo "$c"; echo ; echo "split"; IFS='=======' c_split=($c) ;# &lt;---- LINE TO BE CHANGED for i in ${c_split[@]} do echo "------ new part ------" echo "$i" done </code></pre> <p>Gives output:</p> <pre><code>more complex string AA=A B=BB ======= C==CC DD=D ======= EEE FF split ------ new part ------ AA ------ new part ------ A B ------ new part ------ BB ------ new part ------ ------ new part ------ ------ new part ------ ------ new part ------ ------ new part ------ ------ new part ------ ------ new part ------ C ------ new part ------ ------ new part ------ CC DD ------ new part ------ D ------ new part ------ ------ new part ------ ------ new part ------ ------ new part ------ ------ new part ------ ------ new part ------ ------ new part ------ EEE FF </code></pre> <p>I would like the second output to be like </p> <pre><code>------ new part ------ AA=A B=BB ------ new part ------ C==CC DD=D ------ new part ------ EEE FF </code></pre> <p>I.e. to <strong>split</strong> the string on a <strong>sequence of characters</strong>, instead of one. How can I do this?</p> <p>I am looking for an answer that would only modify this line in the second script:</p> <pre><code>IFS='=======' c_split=($c) ;# &lt;---- LINE TO BE CHANGED </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.
