quick start and stop functions for runit('s runsvdir)

I've been playing around with HomeBrew and I actually like it much more than I'd expected. I was in the process of migrating many services away from my pkgsrc and MacPorts setup and decided to write a couple of handy little shell functions to manage runit:

 1 #!/bin/ksh

 2 my_pathadd PATH ~/bin ~/scripts ~/.bin

 3 

 4 

 5 runit_start(){

 6     #handy little function for starting runit on a service directory speified

 7     #by ${SERVDIR}. 

 8     SERVDIR="/usr/local/var/service"

 9     RUNSVCMD="runsvdir -P ${SERVDIR}"

10 

11     if { ps -auxww | grep ${RUNSVCMD} | grep -v 'grep' }; then

12         echo 'already running'

13     else 

14         echo -n "starting runsvdir on ${SERVDIR}: "

15         #nohup runsvdir -P ${SERVDIR} &

16         eval nohup ${RUNSVCMD} &

17     fi

18 }

19 

20 

21 runit_stop(){

22     #function to stop runit

23     typeset i

24     for i in $(ps -auxww|grep ${RUNSVCMD}|grep -v 'grep'|awk '{print $2}'); do

25         kill -1 ${i}

26     done

27 }

28 

29 runit_status(){

30     {ps -auxww|grep ${RUNSVCMD}|grep -v 'grep';} 2> /dev/null || echo "not running"

31 }


Updated to be portable across KSH and ZSH.... I don't care enough about BASH to check compatibility there (10-11-10):

SERVDIR="/usr/local/var/service"
RUNSVCMD="/usr/local/bin/runsvdir -P ${SERVDIR}"

runit_start(){
    #handy little function for starting runit on a service directory speified
    #by ${SERVDIR}. 
    if { ps -auxww | grep "${RUNSVCMD}" | grep -v 'grep' 2> /dev/null ;} ; then
        echo 'already running'
    else 
        echo -n "starting runsvdir on ${SERVDIR}: "
        #nohup runsvdir -P ${SERVDIR} &
        eval nohup " " ${RUNSVCMD} &
    fi
}


runit_stop(){
    #function to stop runit
    typeset i
    for i in $(ps -auxww|grep "${RUNSVCMD}"|grep -v 'grep'|awk '{print $2}'); do
        kill -1 ${i}
    done
}

runit_status(){
    { ps -auxww|grep "${RUNSVCMD}"|grep -v 'grep' 2> /dev/null ;} ||\
        echo "not running"
}
