    <p>I am trying to use ren-regexp to replace a character in filenames like so:</p> <pre><code>./ren-regexp.pl "s/_/-/g" *.jpg </code></pre> <p>Which I think should replace _ with - in filenames that are jpgs, but what I get is:</p> <pre><code>./ren-regexp.pl: line 4: syntax error near unexpected token `newline' ./ren-regexp.pl: line 4: `&lt;!DOCTYPE html&gt;' </code></pre> <p>I also tried</p> <pre><code>perl ren-regexp.pl "s/_/-/g" *.jpg </code></pre> <p>Which resulted in lots of errors such as:</p> <pre><code>Bareword found where operator expected at ren-regexp.pl line 252, near "time class" (Do you need to predeclare time?) Bareword found where operator expected at ren-regexp.pl line 252, near ""js-relative-date" datetime" (Missing operator before datetime?) Bareword found where operator expected at ren-regexp.pl line 252, near ""2011-04-13T16:40:41-07:00" title" (Missing operator before title?) Number found where operator expected at ren-regexp.pl line 252, near "April 13" (Do you need to predeclare April?) Bareword found where operator expected at ren-regexp.pl line 262, near ""/msabramo/ren-regexp/tree/17026c762c41e2b88ed91bf78b63e54859b706e5" class" (Missing operator before class?) </code></pre> <p>I tried using the examples shown on the GitHub page as well as here:</p> <p><a href="https://stackoverflow.com/questions/5630310/mass-replace-characters-in-filenames-from-terminal/5630338#5630338">Mass replace characters in filenames from terminal?</a></p> <p>Where am I going wrong? Running just 'perl ren-regexp.pl' by itself also results in the above set of errors.</p>

    1. COare you sure you have a good download? sounds like your program is bad. What does “ren-regexp.pl” look like around line 250-260?

    2. COThat script, by the looks of it, is quite... poorly written. Does not even use strict and warnings, and looks to be quite old.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
