Re: [Dev-luatex] os.exec and waiting for process

Dear Taco, dear all,

Reinhard Kotucha wrote a support script in texlua but there is a strange thing: os.exec(...) does not wait for the process to terminate.

Now my question is: Is there any way to do that, i.e., to call a different program and wait for it to terminate, resembling the perl 'system' call.

For that, you should use os.execute() from the core lua. The function os.exec() *replaces* the current process with the to-be-executed process, and never returns. Best wishes, Taco
