I am producing a series of files in a shell script with mtxrun --autogenerate --script context inputDoing exit mtxrun... shows there is no exit number to test in the shell, or to ste a shell variable to that value.
I can set a global macro \ExitStatus to an exit value depending on success or failure, pass that on to mtxrun as exit statusd and test that in the script.
For example:
\starttext
\xmlprocessbuffer{notes}{notes}{}
\doif{\ExitStatus}{notok}{"let mtxrun return value 1 as error in UNIX"}
\stoptext
After that it would be possible in the shell script to delete the pdf produced, what is my intention in this case.
Is this an option or is there presently another (standard) procedure to communicate from ConTeXt to the shell.
