I want to setup a launchagent to do the following on login:
Start screen
Start a processes inside the screen
Detach the screen
What I do now is, manually:
$ screen -h 5000 -DRRS foobar
[wait a second for screen to start]
$ foobar
[wait a second for footer to start]
^a^d
(that detaches the screen so that I can later, either locally or via a remote
terminal session type
$ screen -h 5000 -DRRS foobar
And be right back in that session.
(in the initial command, the -DRR part of the flag is not needed, but I type
the whole thing so that I can simply use the same command in the history
regardless of if I am starting a new session or reconnecting to an existing one)
I tried this with irssi, but it’s not working (and I’m not logging any errors
form it):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"

</plist>
I then tried:
<key>ProgramArguments</key>
<array>
<string>/usr/bin/screen -dmS irc irssi</string>
</array>
But I get:

Could not find and/or execute program specified by service: 2: No such file or
directory: /usr/bin/screen -dmS irc irssi
If I remove the full path, I get:
4/9/15 05:19:48.494 com.apple.xpc.launchd[1]: (com.kreme.home.irssi[76355])
Service could not initialize: 14D131: xpcproxy + 13421
[1402][E34BADE4-4125-3886-AA5B-08E47BD0E884]: 0x2
Any ideas?

a vital ingredient of success is not knowing that what you're attempting
can't be done. A person ignorant of the possibility of failure can be a
half-brick in the path of the bicycle of history.
