Howdy, Most Linux and BSD distributions ship with a version of dd that displays the status of a copy operation when a SIGUSR1 signal is received. For some reason /usr/bin/dd on Solaris hosts doesn't contain this capability, and I would like to add it. After reading through the source code for dd.c, it looks like adding this support would be as simple as installing a signal handler for SIGUSR1, and having it call the function stats. I am attaching code (which I copied from the dd that ships with Fedora Core Linux) [1] to add this support to /usr/bin/dd, and have tested it on my build 54 machine. Would it be possible to integrate this or something similar to opensolaris (assuming this doesn't break some rule defined by the SUS or POSIX)?
Thanks, - Ryan -- UNIX Administrator http://prefetch.net [1] /* Create a signal handler for SIGUSR1 so dd can display stats on active copies.*/ struct sigaction sa; memset(&sa, 0, sizeof(sa)); sa.sa_handler = stats; sa.sa_flags = SA_RESTART; sigemptyset(&sa.sa_mask); sigaction(SIGUSR1, &sa, 0);
