Bash Script for handling an experiment code |
|
|
I rearanged the files in "examples/experiment" as the attached "mtest_exp.zip". I re-write the start/stop script as the attached "daq.sh". The script "daq.sh" can be re-used for many experiments. The user only needs to provide an script "daq_env.sh" as the following containing the settings for the experiment environment.
#!/bin/sh
[ ! "$MIDASSYS" ] && MIDASSYS=/opt/MIDAS.PSI/Version/Current
[ ! "$HTTPPORT" ] && HTTPPORT=8080
[ ! "$SRVHOST" ] && SRVHOST=localhost
LOGGER=${MIDASSYS}/bin/mlogger
EXPPATH=/home/das/online/test
CODEPATH=${EXPPATH}/code
LOGGER=${MIDASSYS}/bin/mlogger
PROG_FE=${CODEPATH}/frontend
PROG_ANA=${CODEPATH}/analyzer
if [ ! "$MIDAS_EXPTAB" ]; then
MIDAS_DIR=${EXPPATH}
else
MIDAS_EXPT_NAME="test"
fi
I hope this can be helpful.  There seem to be some problems such as:
1. When several experiments are defined, the $LOGGER may be not the one used for this exp.
2. The "pidof" may be not in some platforms, so this script is limited.
Hope anybody can help me to improve it for general purpose. All my best! |
