Perl system call
- by claferri
I'm a beginner in Perl and I have some trouble using the "system" call. Here is a little piece of code where I try to execute 2 shell commands :
# First command is :
# dot -Tpng $dottmpfile > $pngfile
# Second command is :
# rm $dottmpfile
if (!($pngfile eq "")) {
my @args = ("dot", "-Tpng", $dottmpfile, " > ", $pngfile);
system (join (' ' , @args ))
or die "system @args failed : $!";
unlink $dottmpfile;
}
EDIT : Here is my code now, and I still get an error :
system dot -Tpng toto.dot > toto.png failed : Inappropriate ioctl for device at /home/claferri/bin/fractal.pl line 79.
I've used this to produce this piece of code.
