Hello all,
I can't seem to get the correct syntak to check for NO items on the command line.
#!/usr/local/ActivePerl-5.16/bin/perl
use POSIX qw/strftime/;
sub fixdir {
my $dir = shift;
opendir my $DH, $dir or die "Not Found....$dir: $!";
while (my $f = readdir $DH) {
next if grep $_ eq $f, qw/. ../;
(my $new = $f) =~ s/[^a-zA-Z0-9_.]/_/g;
next if ($new eq $f);
while ( -e "$dir/$new") { $new .= "1"; }
print STDERR "Renaming: $f -> $new\n";
rename "$dir/$f", "$dir/$new";
fixdir("$dir/$new") if -d "$dir/$new";
}
}
$Do_Dir = @ARGV[0];
print("ARG=", "$Do_Dir", "<<<<<<\n");
if ("$Do_Dir" == null ) {
print ("No Folder Name given!\n");
exit; }
print( "The Folder Name is: ", "$Do_Dir", "\n" );
fixdir($Do_Dir);
print "Done..."
produces this....
9858-215-rfleisch:test_it p00015282$ ./Change_FName2.pl these
ARG=these<<<<<<
No Folder Name given!
9858-215-rfleisch:test_it p00015282$ ./Change_FName2.pl
ARG=<<<<<<
No Folder Name given!
9858-215-rfleisch:test_it p00015282$
Notice the SAME results ????????
Thank....

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
