How to Add Variables to EPICS logging for SBS
1. Edit EpicsToFile, add your variable. 2. Might want run this with TESTPRINT=1 and run EpicsToFile interactively to check it. Don't forget to restore TESTPRINT=0. 3. Kill the current running of EpicsToFile [sbs-onl@adaq1 halla]$ ps awx | grep EpicsToFile 4018 pts/69 S+ 0:00 grep --color=auto EpicsToFile 10161 ? S 1:03 /bin/ksh /adaqfs/home/sbs-onl/logentry_scripts/halla//EpicsToFile kill -9 10161 4. Then wait. The cron script "startCron" will restart it in a few minutes. Perhaps check the process list to be sure.
One fly in the ointment at the moment is that if someone is doing "less EpicsToFile" or "more EpicsToFile" on adaq1, then unfortunately startCron is not smart enough to restart EpicsToFile. It is smart enough to ignore emacs sessions. In the meantime, kill the "less" command, too.
[sbs-onl@adaq1 halla]$ ps awx | grep EpicsToFile 2312 pts/69 T 0:00 less EpicsToFile 3034 pts/69 S+ 0:00 grep --color=auto EpicsToFile 10161 ? S 1:04 /bin/ksh /adaqfs/home/sbs-onl/logentry_scripts/halla//EpicsToFile kill -9 2312 kill -9 10161
