    <p>Look.</p> <pre><code># test 5 proc t5 {} { send "ls &gt; totoExpect.txt\r" send "cat &lt; totoExpect.txt | wc -l &gt; titiExpect.txt\r" send "cat titiExpect.txt\r" expect -re "(0|1|2|3|4|5|6|7|8|9)+.*&gt;" { ok 5; } default { abort 5 } system "rm totoExpect.txt titiExpect.txt" } </code></pre> <p>The first <code>send</code> crates a file named <code>totoExpect.txt\r</code>.</p> <p>The second <code>send</code> generates a file named <code>titiExpect.txt\r</code>. The <code>cat</code> part actually fails, because there is no file <code>totoExpect.txt</code>, but since the command is part of a pipe, and not the last command in said pipe, expect will not catch that as an error. (All you'll see is that the <code>titiExpect.txt\r</code> file will be empty.)</p> <p>The <code>\r</code> above is the CR character, and probably the reason you have missed it. In Linux, it is perfectly allowed character in file names (as only <code>/</code> and <code>\0</code> are forbidden). Just remove it from your test and you'll find it works fine.</p> <p>Or, if you insist on keeping it, then keep it consistently:</p> <pre><code># test 5 proc t5 {} { send "ls &gt; totoExpect.txt\r" send "cat &lt; totoExpect.txt\r | wc -l &gt; titiExpect.txt\r" send "cat titiExpect.txt\r" expect -re "(0|1|2|3|4|5|6|7|8|9)+.*&gt;" { ok 5; } default { abort 5 } system "rm totoExpect.txt\r titiExpect.txt\r" } </code></pre> <p>Finally, when removing files, it is recommended to use the <code>-f</code> flag, so <code>rm</code> does not complain if one of the files happens to not exist.</p> <p>My suggestion is to rewrite that test as</p> <pre><code># test 5 proc t5 {} { send "ls &gt; totoExpect.txt" send "cat &lt; totoExpect.txt | wc -l &gt; titiExpect.txt" send "cat titiExpect.txt" expect -re "(0|1|2|3|4|5|6|7|8|9)+.*&gt;" { ok 5; } default { abort 5 } system "rm -f totoExpect.txt titiExpect.txt" } </code></pre> <p>eradicating those erratic <code>\r</code>s.</p>

    2. COThank you by the answer In fact (that was my fault, i didnt say it), the command reader i did utilise the \ as escape character, so the name saved is not ended by \r. So removing that not worked at all.. i still have the problem, but the -f really helped, now at least it doesnt crash...

    3. CO@FernandoP: Did you actually verify it? In Linux, `\r` = CR = ASCII 13, is a valid character in file names. Run `touch $'titiExpect.txt\r'` in a real Bash shell to see what I mean. (`$'foo'` is just the way you specify `foo` with C-style backslash escapes in Bash.)

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).
