HI i ve got a third party DB. Fo that DB have no drivers at all. But have sql utilities i want to run tis command from perl script and parse output.

when i use just open 

my $sql = "select * from users";
open (COMMAND, "| /opt/sql " ) || die $!;
print (COMMAND "connect credentials")
print (COMMAND "$sql\n");

output fine 
--> 4, 4, Reporting, , F, 1, 0, 0, 0, 0, 0, F, 0, F, 0, F, , BLOB(0)

But when i use just open i can't grab output of $sql command (just in terminal). When i use open2 (and 3 too) 

my $sql = "select * from users";
my $pid = open2 (OUT, IN, "/opt/sql") || die $!;
print (IN "connect credentials");
print (IN "$sql\n");
while (<OUT>) {
    print $_;
}

I've got almost same output but have ">" 
--> 4, >4, Reporting, , F, 1, 0, 0, 0, 0, 0, F, 0, F, 0, F, , BLOB(0)

I guess this trouble in terminal environment (but maybe and not). Can anyone tell me can i grab clear output in this is situation?

In reply to open2 or 3 run command using pty by klimenkoandrey
