note afoken <p>I prefer daemontools for background processes, as explained in [id://794980]. No need to add a single line of code to your script, no race conditions when handling PID files (because daemontools do not need PID files), and a simple control mechanism. Just write a char to a pipe or let the svc utility do that for you.</p> <p><small>(And yes, djb's behaviour regarding <c>errno</c> is just silly and childish. Apply the patch from <a href="http://thedjbway.org/daemontools/installation.html">thedjbway.org</a> or complain loudly to djb that he does not want to accept the C standards. And by the way, also apply the other patch that adds support for <c>SIGQUIT</c>, <c>SIGUSR1</c>, and <c>SIGUSR2</c>.)</small></p> <p>Alexander</p> <div class="pmsig"><div class="pmsig-747201"> --<br> Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-) </div></div> 799688 799688
