splitOnce has asked for the wisdom of the Perl Monks concerning the following question:

Hello guys, I know this is an easy one but since I am new , I would have problems like this : I need to check weather a file exists or not under a certain directory ,, the file 
$targetFile = "theFile"

[download]
and I know the directory as well, 
/bin/do/foo

[download]
so I need to know if it exists under foo, knowing that I am not under foo when searching for that file or I could be as well, I tried the -e and local but don't seem to work ,, thanks for hints on this one .

    if(-e "/bin/do/foo/$targetFile") {
    print "is there!\n";
} else {
    print "someone stoled it...\n";
}

      I'd rather go with 
      if(-f "/bin/do/foo/$targetFile") {
    print "is there!\n";
} else {
    print "someone stoled it...\n";
}

      to check if it's actually a file (that exists), as the -e may also return true on a directory.

    What's wrong with: 
    my $exists = -e "/bin/do/foo/$theFile";
