store perl -c result into a array 1

[NEVERSLEEP]

lets say u do
$value = system($command);
it will return a 0 or 1 depending if it succed
so i was wondering how to store
@value = ?????('perl -c $file');
# so that $value[0] contain the 1st error and so on...

thanks again (...i keep saying that to u guys ) ---------------------------------------

Use backticks, like this:

my @output_lines = `perl -c $file`;

each line of output from the command you are executing will
be stored as an element of the array. I'm not sure if
standard error gets included by default - it may be that
only standard output gets included. You might have to do
something more to get standard error included as well.

I found some information in the perldocs about capturing
STDERR from an external command - do this:

perldoc -q STDERR

the 1st topic that comes up is

How can I capture STDERR from an external command?

so hopefully that will give you some ideas.

heem i dont seem to get this right...

my $var = "drive:\\path\\to\\valid\\script.pl";
my @storer = 'perl -c $file';
my $counter = 1;
foreach (@storer) {
 print "\n$counter : $_";
 $counter++;
}

will output
1 : perl -c $file

and if we change the ' to "
the output is now
1 : perl -c drive:\\path\\to\\valid\\script.pl

since when that quots and double quotes make a difference ?

yep variables in single quotes are just left as text, variables in double quotes are interpreted and their values inserted into the string Mike

On a Us keyboard the key to the left of 1 (not the number pad) is the back tick... thats the key you want to use to run a system command an capture the output.

$someval = `hostname`;

Neversleep -- copy and paste Yauncin's code above, that will give you the correct code. Mike

~ is created while holding shift, ` is created when not, ` is a backtick. ----------------------------------------------------------------------------------
