导读:我编写了一个脚本来检查可用内存(使用vmstat和awk),然后在少于25%的空闲时清除内存.然后在清除之后,我的Mac说(是愚蠢的机器人声音)大声可用内存的整数.我发现它比消息框弹出窗口更少侵入,但是我的妻子讨厌它,因为她有几天在家工作,这让她很烦恼. 我正在寻找
我编写了一个脚本来检查可用内存(使用vmstat和awk),然后在少于25%的空闲时清除内存.然后在清除之后,我的Mac说(是愚蠢的机器人声音)大声可用内存的整数.我发现它比消息框弹出窗口更少侵入,但是我的妻子讨厌它,因为她有几天在家工作,这让她很烦恼.
我正在寻找一种在检测到击键或鼠标移动时设置全局变量(甚至触摸/删除临时文件)的方法.这样,机器空闲时机器人的声音会很安静.我一直在寻找约3个小时没有运气.我用这个片段走在了正确的轨道上: set idleTime to (do shell script "ioreg -c IOHIDSystem | perl -ane 'if (/Idle/) {$idle=(pop @F)/1000000000; print $idle,"";last}'") set initIdleTime to idleTime repeat while idleTime ≥ initIdleTime set idleTime to (do shell script "ioreg -c IOHIDSystem | perl -ane 'if (/Idle/) {$idle=(pop @F)/1000000000; print $idle,"";last}'") end repeat 它会“冻结”提示,然后在移动鼠标或按下某个键时输出一个数字,但我不知道perl所以我无法修改它.如果可能的话,我宁愿坚持使用bash. 顺便说一句,这是脚本,以防任何人想要使用它们.有些我修改了第一个,复制了第二个并写了第三个.我在cron中设置第三个每10分钟运行一次. #!/bin/bash # -- guns # # Purge inactive memory with rapid i/o # # 26 November 2007 # 'killall $command' is still printing to the terminal # declare variables before= after= memPurged= pageSize= pagesPurged= AvailMem= timeout=5 # in seconds command="du /" showUsage="Usage: $(basename $0) [-h] [-t seconds] [-c "command"]" function printError() { echo >&2 $showUsage echo >&2 echo >&2 "See '$(basename $0) -h' for more details." } function printHelp() { echo "Purge inactive memory with rapid i/o." echo echo $showUsage echo echo "Supported Options" echo "-----------------" echo "-t{seconds}tSet the amount of time for the command to run. Default" echo "ttis 5 seconds." echo "-c{"command"}tSet the command to run. Default is 'du /'" echo "-httDisplay this help and exit" } function getMemFree() { # the "$3-0" bit is a dirty way to chop the period at the end vm_stat | awk '/Pages free/ {intMemFree=$3-0; print intMemFree}' } function getPageSize() { vm_stat | awk '/page size/ {print $8}' } # # Main # while getopts ":ht:c:" option; do case $option in h ) printHelp; exit;; t ) timeout=$OPTARG;; c ) command=$OPTARG;; ?) echo >&2 "Invalid option!n"; printError; exit 3 esac done shift $(($OPTIND-1)) before=$(getMemFree) purge # set variables after=$(getMemFree) let pagesPurged=$after-$before pageSize=$(getPageSize) # calculate and print let memPurged=($pagesPurged * $pageSize / 2**20) let availMem=($after * $pageSize / 2**20) printf "%d MB purged." $memPurged say $availMem 和 #!/usr/bin/python import subprocess import re # Get process info ps = subprocess.Popen(['ps','-caxm','-orss,comm'],stdout=subprocess.PIPE).communicate()[0] vm = subprocess.Popen(['vm_stat'],stdout=subprocess.PIPE).communicate()[0] # Iterate processes processLines = ps.split('n') sep = re.compile('[s]+') rssTotal = 0 # kB for row in range(1,len(processLines)): rowText = processLines[row].strip() rowElements = sep.split(rowText) try: rss = float(rowElements[0]) * 1024 except: rss = 0 # ignore... rssTotal += rss # Process vm_stat vmLines = vm.split('n') sep = re.compile(':[s]+') vmStats = {} for row in range(1,len(vmLines)-2): rowText = vmLines[row].strip() rowElements = sep.split(rowText) vmStats[(rowElements[0])] = int(rowElements[1].strip('.')) * 4096 print '%d' % ( vmStats["Pages free"]/1024/1024 ) 最后 #!/bin/bash mf=$(perl ~/scripts/py/memfree.py) if [ "$mf" -lt 2000 ] then sh2 ~/scripts/memclean.sh else exit fi 解决方法
WINRAR!
