Eu tentei muitas variações diferentes sobre isso, mas simplesmente não consigo fazê-lo funcionar.

Eu tenho um arquivo plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>Label</key>
        <string>com.ilium007.handbrake</string>
        <key>ProgramArguments</key>
        <array>
                <string>/bin/bash</string>
                <string>/Users/ilium007/support/scripts/handbrake/handbrake.sh &gt;&gt; /Users/ilium007/support/scripts/handbrake/logs/handbrake_encode.log</string>
                <!--<string>&gt;&gt;</string>-->
                <!--<string>/Users/ilium007/support/scripts/handbrake/logs/handbrake_encode.log</string>-->
        </array>
        <key>RunAtLoad</key>
        <true/>
        <key>StartInterval</key>
        <integer>60</integer>
</dict>
</plist>

Observe os comentários lá.

Eu quero canalizar a saída do script handbrake.sh para um arquivo de log e tentei fazê-lo, mas continuo recebendo um erro "nenhum tal arquivo" em system.log no OSX.

Nov  3 18:03:54 macmini com.ilium007.handbrake[15348]: /bin/bash: /Users/ilium007/support/scripts/handbrake/handbrake.sh >> /Users/ilium007/support/scripts/handbrake/logs/handbrake_encode.log: No such file or directory Nov  3 18:03:54 macmini com.apple.launchd.peruser.501[162] (com.ilium007.handbrake[15348]): Exited with code: 127

Se eu alterar o plist para o seguinte, ele é executado, mas não obtenho nenhum log, então presumo que esteja executando apenas o primeiro argumento:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>Label</key>
        <string>com.ilium007.handbrake</string>
        <key>ProgramArguments</key>
        <array>
                <string>/bin/bash</string>
                <string>/Users/ilium007/support/scripts/handbrake/handbrake.sh</string>
                <string>&gt;&gt;</string>
                <string>/Users/ilium007/support/scripts/handbrake/logs/handbrake_encode.log</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
        <key>StartInterval</key>
        <integer>60</integer>
</dict>
</plist>

O comando que gostaria de executar via launchd é:

/Users/ilium007/support/scripts/handbrake/handbrake.sh >> /Users/ilium007/support/scripts/handbrake/logs/handbrake_encode.log

Nada aparece no arquivo de log. Mas se eu executar esse comando no terminal, obtenho conteúdo no log. Qualquer ajuda seria apreciada.
