在 perl 中执行命令时出现问题

Question

I have the below code:

chdir glob "/home/test/test1/test2/perl*";
@testList = exec "cat test.in | grep build | awk '{print \$2}'";
foreach my $testList(@testList) {
    chdir "/home/test/test1/$testList";
    exec "cat test.out | grep -w 'PASSED'";
}

After I run the above code, it gives the output for only the below:

chdir glob "/home/test/test1/test2/perl*";
@testList = exec "cat test.in | grep build | awk '{print \$2}'";

but not the other two lines below. I only want the output for the lines:

foreach my $testList(@testList) {
    chdir "$opts->{/home/test/test1$testList";
    exec "cat test.out | grep -w 'PASSED'";

and not

chdir glob "/home/test/test1/test2/perl*";
@testList = exec "cat test.in | grep build | awk '{print \$2}'";

Please help.

Answer 1

exec and system are returning exit code.

Try:

@testList = `cat test.in | grep build | awk '{print \$2}'`;
