in reply to system and -e question

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

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

"testing output" is printed

That sort of belies your claim that $file2 doesn't exist. From the information you gave, there is no way to tell which directory the soft link was created in and which directory you did the ls in. If the file name of the soft link is "/a/b/my_link", and you ran your program in the directory /programming/perl/ and you did the ls in the same directory as the one in which you ran your program, then ls won't list the link. But when you do the test -e "/a/b/my_link", it will return true.

You might want to read the details of man ln to see if you can spot what happened. Or you might simply want to try an ls -al.

[msh210]: About time... last time I was right was... I don't even remember when.
[shmem]: perl -e 'warn "test$/", ^@^ '
[Eily]: well, at least it's right about warn doing the same thing as die :)
[shmem]: same with undef as last element
[msh210]: oh, good point. It's the best kind of correct
[shmem]: msh210: but I'd not call it a lie outright. That's when you do know the truth.
[msh210]: I don't have sendmail (I'm on MS Windows), so does one of you think you can report the bug?
[shmem]: msh210: 'tis about time to tell the sad truth to perl5porters - via perlbug
[msh210]: probably whoever wrote that actually knows the truth
[shmem]: msh210: you can save the perlbug text in a file and send that via your mail agent of choice
