Again, I'm very sorry for the amateur post. I'm reletively new to shell scripting so please bear with me.
I have a script that execute another script which stops a particular set of services for my application. IF the execution is successful, I want to check for any hung ESSSVR processes.
Am I capturing the flow correctly here? Normally in DOS wed just use a GOTO label.
Essentially, if the success code is zero, will it jump over the else to proceed to the next execution? Or do I need to inslude the ps -ef portion in the first If/then branch?
Like this:
Code:
#:: SET SCRIPT NAME
_SN=STOP_ESSBASE_SVCS
#:: SET PATHS
_MAINPATH=/home/essadmin/Hyperion_Batch/
_LOGPATH=Logs/
_ERRORPATH=Errors/
#:: SET DATE & TIME VARIBLES:
_DAY=$(date +%d)
_MONTH=$(date +%m)
_YEAR=$(date +%Y)
_DATESTAMP=${_YEAR}${_MONTH}${_DAY}
_HOUR=$(date +%H)
_MINUTE=$(date +%M)
_SECOND=$(date +%S)
_TIME=${_HOUR}${_MINUTE}
_DATETIMESTAMP=$_DATESTAMP-$_TIME
#:: Prepare Log and Error File Directories
_ARC_LF=${_MAINPATH}${_LOGPATH}${_YEAR}${_MONTH}
_ARC_EF=${_MAINPATH}${_ERRORPATH}${_YEAR}${_MONTH}
mkdir -p ${_ARC_LF}
mkdir -p ${_ARC_EF}
#:: Prepare Filename Format
_FN=${_DATESTAMP}_${_SN}
#:: Prepare STDOUT & STDERR
_LF=${_ARC_LF}/${_FN}.log
_EF=${_ARC_EF}/${_FN}.err
exec 2>${_EF} > ${_LF}
#:: Execute script commands
echo ---------------------------------------------------------
echo "${_SN} beginning at ${_TIME}"
echo .
echo "Stop Essbase Services"
echo ---------------------------------------------------------
./home/essadmin/scripts/shutdown.sh
if [ $? -eq 0 ]
then
echo ---------------------------------------------------------
echo "Essbase Services Stopped Successfully!"
echo ---------------------------------------------------------
echo -------------------------------------------------------
echo "Terminate Hung Services"
echo -------------------------------------------------------
_SERVICE=ESSSVR
ps -ef | grep ${_SERVICE} | awk '{print $2}' | xargs kill -9
if [ $? -eq 0 ]
then
echo -------------------------------------------------------
echo "Service Terminated Successfully!"
echo -------------------------------------------------------
trap "[ -s ${_EF} ] || rm -f ${_EF} ] && rmdir ${_ARC_EF}" EXIT 0
else
echo ------------------------------------------------------
echo "No Service Available to Termininate!"
echo ------------------------------------------------------
fi
exit 0
else
echo -------------------------------------------------------
echo "Essbase Services Stopped Unsuccessfully!"
echo -------------------------------------------------------
fi
exit 1
How do I define and call a subroutine in a ksh script (or any shell)? I'm writing a script that uses a lot of the same code over and over and I don't want to waste time/space.

I'm maintaining a variety of programs (mostly in Perl) I didn't build, and the perllib is huge on the server. When I run across a user-defined subroutine it takes me at least an hour to look through all the logical places, and sometimes I still can't find the definition.
Is there an easy way to... (2 Replies)
Hello
This should be easy, but bash is giving me headaches.
At the command line the following command works:
duplicity --include /home --exclude '**' / file:///foo
Doing that from a script is not straightforward. Note that it is basically a requirement that I place the... (3 Replies)
