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
