Command line check file status

Question

I have written a shell script that converts the file to flv then injects it with metadata and does a couple other things. However, the injection starts after about 10 seconds or so. I have read that the shell command "wait" will help but I don't think it is working because it doesn't know when the file has converted completely. Is there a way to know when the file has converted 100%? Can I get a variable and check it and when it is 100 or something then I can move on with my script? Is this possible?

The command line compressor command does not "block" the way you would normally expect a command line tool to do. It returns as soon as it submits the job. Qmaster then manages the job on the queue.
In order to do what you want, you need to use a separate command in a loop that queries Qmaster for your job's status. It returns xml-ish type stuff that you then need to parse out to get your "percent complete or whatever. Once the status returns as "100%" or whatever, you then know you can run your injection command.
To see what I'm talking about, when you submit your job, it should return a string with "jobid" and "batchid" to stdout. Try using those in this command.
`/Applications/Utilities/Batch\ Monitor.app/Contents/MacOS/Batch\ Monitor -clusterName <CLUSTERNAME> -jobid <JOBID> -batchid <BATCHID>`
