Question1: I use system call to create a soft link in my Perl code below:

system("ln -s $file1 $file2");

$file2 is not created, why? The same system call works for some other files within the same perl script, Why?

Question2, For $file2 above, when I use code below for testing,

"if (-e $file2) { print "testing output"; }"

"testing output" is printed, looks like $file2 does exit, but when I cannot file $file2 with "ls", and the following perl code cannot find $file2 either.

Is there any explanation for that?

Thanks a lot!
