When executing the following segment of code,
sub list {
my($self)=@_;
my $file = $self->{P_Dir}."/".$self->{Name};
print `ls –l $file`;
}
I get this error:
ls: cannot access –l: No such file or directory
I am not really sure what is causing that, since if I manually type ls -l into the command line, I do not see that error.
That
–that you’ve thankfully copy & pasted is a Unicode en dash character (U+2013) and not the ASCII hyphen character-(U+002D).
