I'm very new to perl. I have been trying to reweite some of my shell scripts to learn
the language. Here's what I've got...
#!/usr/local/bin/perl -w
if ( $#ARGV+1 !=2 ) {
print "\n";
print "usage cat.pl port up\/down\n";
print "\n";
exit;
}
chomp( $port = $ARG
The following subroutine should take an input path (Dir0), process that
directory by recursively calling itself on subdirectories or processing
any files it contains. The problem I am experiencing is that in the
following example file structure it process Dir1 correctly, but after it
returns t
Hello,
I have the following dataset and want to calculate a P/A ratio for each
replicates in the dataset. In this case, treatment 1 has 4 replicats and
treatment2 has 3 replicates. The P/A = [((#of P)*2) + (# of M)]/# of
replicates. The output should be two columns of P/A ratios for two
treatment

That's better written as:
if (@ARGV != 2) {

>print "usage cat.pl port up\/down\n";
>print "\n";
>exit;
>}
>#if (( $status ne 1 ) || ( $status ne 2 )) {

icking in. If status was 2, it would still fail because it didn't
equal 1.
The above says "unless status equals 1 or 2, fail", which is what you need.

You have a logic error. The if test should be:
if (! ( $status eq 1 || $status eq 2)) {

A few other "style" pointers follow:
You can replace this:
if ( $#ARGV+1 !=2) {
with
if ( @ARGV != 2) {

Well, I know better than that. Should be "=" not "eq".

If you are running this on *NIX box, plain old 'find' command is enough
too.

L. Schwartz and Tom Phoenix is excellent.

You should get the two Perl bibles: _Programming Perl 3rd Ed_ by Larry Wall
and _Perl Cookbook_ by by Tom Christiansen and Nathan Torkington.

When I execute this line:
$type eq "unknown" ? $type="human" : $type="both";
$type is always "both". But executing this line:
if ($type eq "unknown") {$type="human"} else {$type="both"};
$type is "human", which is want I want and expect. The context for these
statements in my program is pasted

PRECEDENCE! ?: has higher precedence than =
You want to do it like this:
$type = $type eq 'unknown' ? 'human' : 'both';

You're trying to use the trinary like you would an if-then-else. You
want to instead use it in an assignment:
$type = ($type eq 'unknown') ? 'human' : 'both';
