Hi,

I have the following string:

my $command = "$User_Preferences{"asadminexecutable"} deploy --user=
$User_Preferences{"user"} --passwordfile=
$User_Preferences{"passwordfile"} --host=$User_Preferences{"host"} --
port=$User_Preferences{"port"} $User_Preferences{"pathdeployunit"}";
system($command);

Global symbol "$command" requires explicit package name at
remote_deploy.pl line 55.
syntax error at remote_deploy.pl line 55, at EOF
Missing right curly or square bracket at remote_deploy.pl line 55,
within string
Execution of remote_deploy.pl aborted due to compilation errors.

Any ideas what I need to do to make it possible to execute the
command?

cheers,

//mike

This is a little silly. You do realize that you do not have string,
right? You have

"$User_Preferences{"

followed by the bareword

asadminexecutable

followed by

"} deploy -- ..."

etc.

I would recommend using a LIST argument with system in this case
(see perldoc -f system) unless you need some features of the shell:

system $User_Preferences{asadminexecutable},
'deploy',
"--user=$User_Preferences{user}",
"--passwordfile=$User_Preferences{passwordfile}",
"--host=$User_Preferences{host}",
"--port=$User_Preferences{port}",
"$User_Preferences{pathdeployunit}";

get rid of all the double quotes in the $hash{"lookup"} constructs. you
don't need them and they break the double quoted string they're
interpolated in.

Actually, what you have there is a _quoting_ problem.

First of all there is no reason to delimit hash keys with the double
quotes. But if you're going to do that, you shouldn't surround the
whole string literal with double quotes. Use single quotes
( $User_Preferences{'user'} -- if any -- $User_Preferences{user} --
works just fine. ) or surround the thing with the qq operator, to
allow for the embedded double quotes.

Hi,

I changed it to ( taking all pointers into account):


my [at] args = ($User_Preferences{asadminexecutable}, 'deploy', "--user=
$User_Preferences{user}","--passwordfile=
$User_Preferences{passwordfile}","--host=$User_Preferences{h ost}","--
port=$User_Preferences{port}","$User_Preferences{pathdeployu nit}");

system( [at] args) == 0 or die "system [at] args failed: $?"
if ($? == -1) {
print "failed to execute: $!\n";
}
elsif ($? & 127) {
printf "child died with signal %d, %s coredump\n",
($? & 127), ($? & 128) ? 'with' : 'without';
}
else {
printf "child exited with value %d\n", $? >> 8;
}

I get the following error:

Possible unintended interpolation of [at] args in string at
remote_deploy.pl line 63.
syntax error at remote_deploy.pl line 63, near "system"
Global symbol " [at] args" requires explicit package name at
remote_deploy.pl line 63.
Global symbol " [at] args" requires explicit package name at
remote_deploy.pl line 63.
Execution of remote_deploy.pl aborted due to compilation errors.

Does not really help me as a newbie :-)
Any ideas?

cheers,

^^^ Here is the nasty bit!

There is a semicolon ';' missing after the line with system().

By the way, from the error message 'Global symbol " [at] args" requires
explicit package name' I infer that you use the strict pragma, which
is a good thing. Now learn to interpret the error messages ;-)

Keep on trying!

There is a semi-colon missing at the end of that line.

As a newbie, you would be better helped by reading your code more
carefully rather than asking us to figure out every syntax error.

As a newbie, you might want to learn more before writing deployment
scripts if you don't want to ruin your customers.

Could also make that easier to read:


my [at] args = (
$User_Preferences{asadminexecutable},
'deploy',
"--user=$User_Preferences{user}",
"--passwordfile=$User_Preferences{passwordfile}",
"--host=$User_Preferences{host}",
"--port=$User_Preferences{port}",
"$User_Preferences{pathdeployunit}",
);

my [at] jazz = qw/user passwordfile host port/;
my [at] args = ($User_Preferences{asadminexecutable},
'deploy',
(map "--$_=$User_Preferences{$_}", [at] jazz),
$User_Preferences{pathdeployunit},
);
