#Take out all directories named by numbers under/proc directory (process name is number is process, others such as sys,net are other information)

for pid in `ls -l /proc | grep ^d | awk '{ print $9 }'| grep -v [^0-9]`

#There is only one way for a process to release swap: restart the process. Or wait for it to release itself.

#If the process is automatically released, then we won't write scripts to find it, we will find it because it is not automatically released.

#So we want to list the processes that take up swap and need to be restarted, but init is the ancestor of all processes in the system

#Restarting the init process means restarting the system, which is absolutely not allowed, so there is no need to detect him, so as not to affect the system.

if [ $pid -eq 1 ];then continue;fi # Do not check init process

#Determine whether the change process occupies swap

grep -q "Swap" /proc/$pid/smaps 2>/dev/null

if [ $? -eq 0 ];then #if swap is occupied

swap=$(grep Swap /proc/$pid/smaps | gawk '{ sum+=$2;} END{ print sum }')
