Shellscript - 檢查運行服務

Question

我是新的Shellscript，我收到一些問題。我需要一個腳本來檢查服務是否正在運行，如果它沒有運行，並且不存在該標誌，則啓動所有服務。我做錯了什麼？

#!/bin/bash 

file= "$PIN_HOME/apps/DE_BILL_MI_BRM/alarmistica/flags/intervencao.flag" 

# Check if services are running 
for service in $BRM_SERVICES 
do 
    if [ps -ef | grep $service | grep -v grep | awk 'NR>1{for (i=1;i<=NF;i++)if($i==1) print "Services not running", i}' ]; then 
     echo $service " is not running correctly" 
    else 
     if [ -f "$file" ]; then 
      echo "Flag exists. The service will not start" 
     else 
      echo "$file not found. Starting all services" 
      pin_ctl start all 
     fi  
    fi 
done 

當($i==1)，服務沒有運行！

但結果並不對應。例如，當服務關閉時，腳本不會啓動服務...

對於檢查進程表，請改爲使用pgrep。

#!/bin/bash 

file= "$PIN_HOME/apps/DE_BILL_MI_BRM/alarmistica/flags/intervencao.flag" 

# Check if services are running 
for service in $BRM_SERVICES 
do 
    pgrep -f "$service"; 
    exstat=$?; # This checks the exit status 
    if [ "$exstat" -eq 0 ] && ! [ -f "$file" ]; then 
     echo "pgrep returned exit status $extstat"; 
    else 
     echo "$file not found. Starting all services" 
     pin_ctl start all 
    fi  
done
