How to kill unused gearman functions?

Question

PHP

The essence of the issue is that there is gearman 1.1.8 in it, it is necessary to kill unused functions. How can this be done in CentOS?

for MATCH in $(echo status | nc 127.0.0.1 4730 | grep -v \\. | grep -Pv '^[^\t]+\t0\t' | cut -s -f 1-2 --output- delimiter=\,);
do
gearman -n -w -f ${MATCH%\,*} -c ${MATCH#*\,} > /dev/null;
done

this option doesn't work
