相同的命令在第一次迭代中失败,但是在第二次迭代中传递。有时它会在两次迭代中传递。 $ssh
是Net::SSH::Expect
的对象。
知道这种奇怪的行为吗?
$ssh = Net::SSH::Expect->new(
host => "$host",
password => "$pass",
user => "$id",
raw_pty => 1,
timeout => 50
);
代码段:
&Test("Create exports on Sonas------ No Kerberos");
$no_of_exports=2;
my $fs = "/ibm/gpfs0/";
while($no_of_exports)
{
my $share_name = &get_share_name();
my $path="$fs" . "$share_name";
$cmd="ssh mgmt001st001 mkexport $share_name $path --nfs 'client002\\\\(rw,no_root_squash\\)'";
print "CMD: $cmd";
$out=$ssh->exec("$cmd");
print $out;
--$no_of_exports;
}
输出:

答案 0 :(得分:0)
错误信息就在那里。 Bash正在窒息,因为(
令牌是意外的。你需要再添加两个反斜杠,其中有四个反斜杠
$cmd="ssh mgmt001st001 mkexport $share_name $path --nfs 'client002\\\\(rw,no_root_squash\\)'";
变为
$cmd="ssh mgmt001st001 mkexport $share_name $path --nfs 'client002\\\\\\(rw,no_root_squash\\)'";
