Hello,
My code is below:
$aux = `ls /opt`;
@word = split /\s+/, $aux;
my @bancos = ();
foreach my $i (@word)
{
if ( -e /opt/$i/postgresql.conf )
{
push(@bancos,$i);
}
}
for ($i = 0; $i @bancos; $i++)
{
su postgres -c /usr/local/pgsql/bin/pg_ctl start -D
Hello,
$aux = `ls /opt`;
This is not good since Perl has built-in function for read a dir.
see:
perldoc -f opendir
perldoc -f readdir
su postgres -c /usr/local/pgsql/bin/pg_ctl start -D
@bancos[$i];
'su' is not Perl's function.This is a unix shell command,you need to call it
with

That won't work very well if you have names with embeded spaces. A better
option would be to assign the back-quote results to an array.
my @bancos = ();
Why are you assigning nothing
