本文实例为大家分享了linux内存泄漏检测的shell脚本，供大家参考，具体内容如下

#!/bin/sh

if [ $# -ne 1 ]; then
  echo "usage: `basename $0` process_name"
  exit 1
fi

appname=$1
proc="`ps -ef | grep "$appname" | grep -v "grep" | grep -v "awk" | grep -v $0 | awk '{print $1}'`"

if [ -z $proc ]; then
  echo "invalid process_name"
  exit 1
fi

smaps="/proc/$proc/smaps"
status="/proc/$proc/status"
echo "proc ---$proc----"
oldheap="0"
while :
do
  #heap="`cat $status | grep "vmdata" | awk '{print $2}'`"
  heap=`cat $smaps | grep -a 5 "heap" | grep "rss" | awk '{print $2}'`
  if [ $heap -lt $oldheap ]; then
    echo "`date` heap -`expr $oldheap - $heap` to $heap kb"
    oldheap=$heap
  elif [ $heap -gt $oldheap ]; then
    echo "`date` heap +`expr $heap - $oldheap` to $heap kb"
    oldheap=$heap
  fi
  sleep 1
done
