Yes, I think spawning a shell is the difference though manually backgrounding it in my test script worked ok, just took me a few minutes to figure out what was going on since I didn't think backgrounding was necessary. I was killing the port 9000 sexpect process and then respawning it at the top of the loop as an ugly way of clearing the buffer. > > But doesn't this just always process the first track in the playlist > (which isn't necessarily the one playing) ? > No, index 0 is the currently playing song if you use the dash in the query - from the cli page: Code: -------------------- Set the parameter to "-" to get the playlist data starting from the current song. -------------------- > > btw, if you use wget to post, you don't need netcat, the second sexpect > spawn and the matching sexpect expect/_outs - simply put the result JSON > into a variable. The busybox wget doesn't do post. Haha, I know, get a different version that does, and any sane person would, but I seem to be irrationally hung up on not wanting to bring in extra tools, even though I have to for some things. Just a few minutes ago I finally figured out how to get the json data just using the busybox nc, that was driving me crazy. I couldn't understand why it was just exiting without returning anything. It's the sleep .1 that made all the difference. Here's the little test script I used: Code: -------------------- #!/bin/sh post=$(cat <<'END_HEREDOC' POST /jsonrpc.js HTTP/1.1 HOST: 192.168.1.201:9000 Content-Type: application/json; charset=utf-8 Content-Length: 97 {"id":1,"method":"slim.request","params":["b8:27:eb:94:ae:63",["status","-","1","tags:acgltys"]]} END_HEREDOC ) (echo -e "$post"; sleep .1) | nc 192.168.1.201 9000 | tail --line=+7 > json.txt -------------------- So now I'm thinking about trying the log watching method so I can detect newsong events and retrieve the json with just busybox builtins. ------------------------------------------------------------------------ sodface's Profile: http://forums.slimdevices.com/member.php?userid=19057 View this thread: http://forums.slimdevices.com/showthread.php?t=109694 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
