In other words, that a program change the environment variables of its parent? The general answer is ``no.'' See the comp.unix.questions Frequently Asked Questions list for more information. ---Dan

I have several systems at my disposal and half of them don't have putenv(). Does it really put the enviornmet var back to the caller? Does it do an 'export' as in the Bourne shell? I know you can add on vars to the envior. and pass them down. I know I can RTFM but is late on Sat. and I feel like getting my two cents in. Ricky Glass

You should look at the man page for syslog.conf(5). All you have to do
is add ",/pathtofilename" to each entry that has "/dev/console" in it. This
will send all messages that appear on the console to the named file. After
you edit "/etc/syslog.conf", you will have to send syslogd(8) a SIGHUP so
that it will reread this file.
Hope this help!
