I think you want qq{ } so the $file variable gets interpolated - q{ } will not do variable interpolation.<br>

Hi Garth,<br>
<br>
Thank you for he reply. What I am trying to do is run two programs<br>
simultaneously and pass an argument in the form of a scalar to one of the<br>
programs.<br>
<br>
Here's the code from the program ( I am retyping it as the machine it's on<br>
does not get connected to the internet)<br>
<br>
system(q{ ( evince /usr/local/docs/$file & ) ; gnome-terminal"});<br>
<br>
evince opens with the error message:<br>
<br>
Unhandled MIME type: "x-directory/normal"<br>
<br>
However,<br>
<br>
system(q{ ( evince /usr/local/docs/file_name.tif & ) ; gnome-terminal"});<br>
<br>
works ( the file opens fine and so does the terminal next to it.) I need to<br>
find a way to be able to pass the file name to evince.<br>
<br>
Thanks, again for the reply. Hopefully, this can be solved.<br>
<br>
<br>

I think I'm lost on what you're trying to do; if its not too lengthy, can<br>
you post exactly the script you're trying to run with the environment<br>
variables (e.g. $file) explicitly defined?<br>
<br>
If you're really doing a "perl -e" just to run system, you might consider<br>
making this a shell script instead of a perl script.<br>

The solution below works. But when I have to pass a scalar to the program<br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
it does not. For example if I do something like:<br>
perl -e'system(q{ ( evince $file & ) ; xlogo });'<br>
<br>
evince opens with this error Unhandled MIME type: "x-directory/normal"<br>
<br>
Does any one know how I can remedy this?<br>
<br>
Thanks.<br>

There are better ways of dealing with this (forking, one of the IPC<br>
<br>
modules, etc), but these are a quick and dirty way to do what you<br>
want:<br>
<br>
perl -e'system(q{sh -c "( xlogo & ) ; xlogo "});'<br>
perl -e'system(q{ ( xlogo & ) ; xlogo });'<br>
<br>
(Replacing the xlogo commands with evice and terminal, of course.)<br>
