I'm using the following script to call one of my UUCP feeder sites. The idea is that it should continue to retry the call until the call completes successfully. (There is a problem with noisy phone lines and the antiquated Merit Network which cause calls to fail in midstream): # !/bin/csh # /usr/lib/uucp/uucico -r1 -Ssharkey while ($status != 0) sleep 300 /usr/lib/uucp/uuxqt /usr/lib/uucp/uucico -r1 -Ssharkey end The problem is, that this will go at most twice through the loop and then will exit, regardless of wether uucico failed or succeeded on the last try. I think the problem is that uucico returns different return codes for different types of errors. Could someone send me a list of return codes for uucico. I'm running SCO Xenix 2.3.2 (HDB UUCP).

(There is a problem with | noisy phone lines and the antiquated Merit Network which cause | calls to fail in midstream): I would suggest several changes. This is the script you showed: | # !/bin/csh | # | /usr/lib/uucp/uucico -r1 -Ssharkey | while ($status != 0) | sleep 300 | /usr/lib/uucp/uuxqt | /usr/lib/uucp/uucico -r1 -Ssharkey | end I am not a csh expert, so let me offer a /bin/sh solution: while true do { sleep 300 & /usr/lib/uucp/uuxqt; wait $!; } /usr/lib/uucp/uucico -r1 -Ssharkey && break done /usr/lib/uucp/uuxqt There are two bits of trickyness here... the first is that this is an endless loop, broken only when the uucico executes with good status and the && lets the break take effect. Second, the use of { } bracketing allows the five minute sleep and the uuxqt to run in parallel, ending when both are finished. The $! makes it wait for only the sleep, in case this is part of some other stuff you run and there are other process started. Finally, running uuxqt one last time after uucico is not tricky, just standard practice. Oh, since this is really a shell question I added the shell group to the distribution, if you followup please edit out any group which does not apply to your posting. -- bill davidsen - davidsen@sixhub.uucp (uunet!crdgw1!sixhub!davidsen) sysop *IX BBS and Public Access UNIX moderator of comp.binaries.ibm.pc and 80386 mailing list "Stupidity, like virtue, is its own reward" -me
