Thanks for all your responses.

I think that bash as a programming language is also an everyday tool. The
idea of a strong character that selects all files, is it bad?

everybody,<br> &gt;<br>
&gt; I would like to ask if it is possible to disable expanding asterisk when it<br>
&gt; selects all entries ?<br>
&gt;<br>
&gt; `$ rm * .jpg` with a mistaken space between asterisk and .jpg will delete<br>
&gt; everything in your home directory or in the entire disk.<br>
&gt;<br>
&gt; In my opinion, when the user asks to select &quot;everything&quot; which could \
be `*`<br> &gt; or `path/*`, bash has to show a confirmation prompt to check if the \
user<br> &gt; was not mistaken, this option should be obviously disabled by \
default<br> &gt;<br>
&gt; Another idea: `*` and `/*` should not be interpreted and the user has to<br>
&gt; enter another sequence &quot;more powerful&quot; to emphasize selecting all \
entries (<br> &gt; `^*` would it work just fine ?)<br>
[...]<br>
<br>
zsh does that by default:<br>
<br>
$ rm * .jpg<br>
zsh: sure you want to delete all the files in /tmp [yn]?<br>
<br>
(disabled with &quot;setopt RM_STAR_SILENT&quot;)<br>
<br>
Also in tcsh, though not enabled by default there:<br>
<br>
&gt; set rmstar<br>
&gt; rm *<br>
Do you really want to delete all files? [n/y]<br>
<br>
(they match on &quot;rm *&quot; or &quot;rm dir/*&quot;)<br>
<br>
For bash, you can try this approach:<br>
