pt-stalk top -bn1 causes an error on CentOS

[Fernando Ipar]

At least on CentOS, the following command as included in pt-stalk:

top -bn1

Causes this error:

top: invalid option -- 1

top -bn 1

(with a space in the middle) works as expected:

last pid: 10426; load avg: 0.01, 0.01, 0.00; up 12+22:07:54 21:40:17

This is on:

CentOS release 5.6 (Final)

It works on CentOS 5.8 for the record.

I can't reproduce this:

[vagrant@localhost ~]$ cat /etc/redhat-release
CentOS release 5.6 (Final)

[vagrant@localhost ~]$ cat foo.sh
#!/usr/bin/env bash

top -bn1

[vagrant@localhost ~]$ ./foo.sh
top - 11:26:20 up 7 min, 1 user, load average: 0.42, 0.35, 0.19
...

Daniel,

I realized this happens with top 3.8 beta. It works fine on CentOS with top 3.2.7
You can just close, I'll patch the version used by this customer but I don't think this will affects others.

Thanks,
Fernando.
