Using perl sys command to launch perl scrip

[Guest_imported]

currently I'm doing the following command

system( "$fnf", "$release", "$line", "u&quot

where

$fnf = "perl " . "$base" . "import_dump_and_drop"
$release = <a parameter> #and yeah I checked to make sure it had the right value
$base = &quot;/<dir_name>/<dir_name>/software&quot; #where dir_name is the appropritate directory structure

my problem is that at the beginning of the import_dump_and_drop script I placed a print &quot;HELLO WORLD&quot; and when I run the script above I don't get a thing...

if you have any ideas, suggestions, or comments they would be appriciated. thank you in advace

I notice two things, which may not be issues if they are just typos in your post:

1. You didn't include a space between the $base and the name of the script when you are concatanating in the $fnf assignment.

2. You didnt include the .pl extension in the name of your script.

Like I said these could be just typos during your post, but you may want to check them out. --Derek

&quot;Fear not the storm for this is where we grow strong.&quot;

First thank you.

second sorry $base should have read like this

&quot;/<dir_name>/<dir_name>/software/&quot;

so that the concat for $fnf would read

&quot;perl /<dir_name>/<dir_name>/software/import_dump_and_drop&quot;


as for the extentsion....

I'm on a unix box, and thus far I've never had to put the exention on the file name. and I have several files already running just fine

but since this scripts purpose is to run one scrip against a list of strings <listed in a seperate file> I don't know if that is going to have an tremendous changes, but I believe that since it is unix the system command will understand if the perl script doesn't have an extention so long as I call perl against it

You either have to make the system call all one string or put ALL of the arguments to the program as separate members of the list. Try changing the script to

my $perl = 'perl';
my $fnf = "$base" . "import_dump_and_drop";
system( "$perl", "$fnf", "$release", "$line", "u");

jaa

And, actually, you don't need quotes around variables in the list unless they are being cat'd to another string.

system( $perl, $fnf, $release, $line, "u");

It improves the readability some

jaa
