    <p>You're not too far off. My first fix is changing line 3 to the following:</p> <pre><code>ls -- "${others}".* </code></pre> <p>This will expand <code>$others</code> and allow the globbing to happen. It's the shells responsibility to expand the <code>*</code> to the list of all matching filenames. The list of filenames is then sent to <code>ls</code>. It sounds like in most cases ls will see something like this:</p> <pre><code>file1.001 file1.002 file1.003 ... </code></pre> <p>But, when no files are present, the shell passes the glob to ls and it will see asterisk:</p> <pre><code>file1.* </code></pre> <p>Thus, your line, <code>ls $others"*"</code> appends a literal asterisk which ls will see.</p> <p>Unless you have a file name <code>file1.*</code> (with a literal asterisks), <code>ls</code> will fail.</p> <p>Another option is to use basename:</p> <pre><code>first="$1" others=`basename -- "$first" .001` ls -- "${others}".* </code></pre> <p>Using <code>basename</code> gives you the advantage that it can remove directories, etc.</p> <p>However, as others have pointed out, depending on what you're doing with the list of files, <code>find</code> may be better.</p> <p>EDIT: The double-hyphen doesn't work on all *nix variants but tells the <code>ls</code> and <code>basename</code> commands that no other cli arguments follow. Quoting your variables may be a best practices but I prefer the simplicity of leaving them off unless the data isn't trusted. Know your data and quote appropriately.</p>

    1. COYour variables are not properly quoted, which causes issues if the file names contain spaces or other "special" characters. Use `ls -- "$others"*` and `basename -- "$first"` instead.

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.
