I want command to check if I am already logged in perforce, which returns 0 if I am logged in, otherwise some non-zero value to represent error. how to achieve this from command line?

<code>p4 help login</code> says: <pre class="prettyprint"><code>p4 login [-a -p] [-h <host>] [user] p4 login [-s] [...] The -s flag displays the status of the current ticket (if there is one). </code></pre> Additionally, empirical testing shows that running <code>p4 login -s</code> while logged in returns an exit code of 0, and running it while not logged in returns an exit code of 1.

p4 help login says:

p4 login [-a -p] [-h <host>] [user]
p4 login [-s]

[...]

The -s flag displays the status of the current ticket (if there is one).

Additionally, empirical testing shows that running p4 login -s while logged in returns an exit code of 0, and running it while not logged in returns an exit code of 1.
