Hi all,

I try to write a script that do a complete shutdown of my observatory. I use indi_getprop, indi_setprop and indi_eval for doing some action before the shutdown.

when i use indi_eval like this :
indi_eval -t 0 -w '"CCD Simulator.CCD_EXPOSURE._STATE"==1'
it do the job either in command line or in a shell script.

But, if i want use the same command with variable like this :
it doesn't work because it cannot resolve the INDI_CCD variable. The problem is du to the single quote. I don't know how to resolve this issue.

Does some people have ever had this issue and how to correct it ?

Yes, quoting variable in shell can be tricky.
Other can have better idea, but for me this work. Please note the unclose " in the export command, it is closed in the indi_eval command.

thank you Patrick. With your advises i finished my script and yes, the bash variables are tricky to manipulate.
