#list第五行为下载地址list=(`cat ../tools/list | awk '{print $5}' | sed "1,1d"`)for((i=0;i<${#list[@]};i++));do curl -u wangyong:Abcd1234 -O ${list[i]} war=`echo ${list[i]} | awk -F "/" '{print $NF}'` mv $war ../workapp/done 5、解压war包到指定目录
ssh ${ip} unzip ${tomcat目录}/webapps/${war包名称}.war -d ${tomcat目录}/webapps/${指定目录} 6、多Linux服务器建立信任关系
ssh-keygen -t rsacd ~/.sshscp -r id_rsa.pub $ip:/root/.ssh/$ipssh $ip 'touch ~/.ssh/authorized_keys && chmod 644 ~/.ssh/authorized_keys'ssh $ip "cat ~/.ssh/$ip >> ~/.ssh/authorized_keys"
7、删除某目录下空文件
find ../new/$serve/properties -type f -size 0 -exec rm -f {} \; 8、删除某目录下小于10b的文件
#Delete the files smaller than 10B for i in `ls -l ../new/$serve/properties/ | sed -e '1d' | awk '$5 < 10 {print$NF}'` do rm -rf ../new/$serve/properties/$i done 9、Linux通过alias设置快捷命令
command(){list1=(`cat ~/.bashrc | grep custom`)for((i=0;i<=${#list1[@]};i++));do if [[ "${list1[i]}" = "#custom" ]] then echo "[warn] The command has already been initialized,there's no need to repeat the operation, thank you!" break else path=`pwd` #初始命令 #Initialization commands. echo "#custom" >> ~/.bashrc echo "alias l='ll -al'" >> ~/.bashrc echo "alias conf='cd `echo $path`/../conf'" >> ~/.bashrc echo "alias bin='cd `echo $path`/../bin'" >> ~/.bashrc echo "alias new='cd `echo $path`/../new'" >> ~/.bashrc echo "alias too='cd `echo $path`/../tools'" >> ~/.bashrc echo "alias hostlist='cat `echo $path`/../tools/.hostlist'" >> ~/.bashrc echo "alias un='cd `echo $path`/../'" >> ~/.bashrc echo "alias bak='cd `echo $path`/../bak'" >> ~/.bashrc echo "alias app='cd `echo $path`/../workapp'" >> ~/.bashrc echo "alias ..='cd ../'" >> ~/.bashrc source ~/.bashrc fidone} 10、引用其他shell脚本方法
## ====================================================#### auth:wonter #### date:2014-06-12 #### path:javame.cnblogs.com #### ====================================================###!/bin/sh#引用tool.sh脚本中方法. ../tools/tool.sh#Parameterspar#Capture ip#Capture pathconfig
11、获取脚本自身名称
#Automatically obtain configuration filesname=`echo $0`uname=`echo $name | awk -F "/" '{print $2}' | awk -F "." '{print $1}'`#Uniform configurationserve="$uname" 12、检查是否存在文件夹，没有则新建文件夹
bak_mk="../bak/$serve"new_mk="../new/$serve"if [ ! -d $bak_mk ]; thenmkdir $bak_mkfiif [ ! -d $new_mk ]; thenmkdir $new_mkfi 判断文件是否为空 if [[ -s $file ]]; then
echo "not empty" fi
13、统计脚本执行时间
st=`date +"%Y-%m-%d %H:%M:%S"` #执行方法 start en=`date +"%Y-%m-%d %H:%M:%S"` st_c=`date -d "$st" +%s` en_c=`date -d "$en" +%s` interval=`expr $en_c - $st_c` echo "Start start-up time ：${st}" echo "Start end time ：${en}" echo "total consuming time ：${interval} 秒" 14、shell定义集合
#namelist1=(`cat ../tools/list | grep -v \# | awk '{print $1}' | sed "1,1d"`)#iplist2=(`cat ../tools/list | grep -v \# | awk '{print $2}' | sed "1,1d"`)#servelist3=(`cat ../tools/list | grep -v \# | awk '{print $3}' | sed "1,1d"`)for((i=0;i<=${#list1[@]};i++));do cp ../conf/.model ../conf/${list1[i]}.conf cp ../bin/.model.wy ../bin/${list1[i]}.wy cp ../bin/.model.yw ../bin/${list1[i]}.ywdone 15、记录脚本执行者用户与IP
#Perform operationecho "operator:"read mea=`tty | awk -F "/dev/" '{print $2}'`date "+%Y-%m-%d %H:%M:%S" >> ../logs/operation.logecho `w | grep $a | awk '{print $3}'` "${me} > Perform operation: one" >> ../logs/operation.log 16、shell中的正则语句
for i in `cat ../conf/$confs | grep start | awk -F ">>" '{print $2}' | awk -F "_" '{print $1}'`do if [[ "${i}" == "shiro" ]] then sed -n -e '/>>shiro/,/>>shiro/p' $confs |grep -v '>>shiro' > $pro_shi cat $pro_shi | col -b > ../temp/m1 cat ../temp/m1 > $pro_shi elif [[ "${i}" == "jdbc" ]] then sed -n -e '/>>jdbc/,/>>jdbc/p' $confs |grep -v '>>jdbc' > $pro_jdbc cat $pro_jdbc | col -b > ../temp/m1 cat ../temp/m1 > $pro_jdbc fi done 17、shell写个定时进程（不推荐我这个写法，应该有更好！）
## ====================================================#### auth:wonter #### date:2014-06-12 #### to :timing.sh #### ====================================================###!/bin/shecho "请输入定时阀值（格式：`date +"%Y-%m-%d %H:%M"` ）" read timingecho "定时任务设置完毕，请安心等待..."ti(){while truedo time=`date +"%Y-%m-%d %H:%M"` if [[ "${time}" == "${timing}" ]] then echo "定时任务:" #定时清理日志 rm -rf ../logs/* #定时备份日志 #定时执行脚本 break fidone}ti& 18、通过参数方式执行脚本 tools.sh
#!/bin/shtrust(){#建立信任echo "请输入信任机ip：(提示：需输入三次密码！)"read iptrusts}command(){#初始化命令command}case "$*" in trust) trust ;; command) command ;; *) echo "----------------------------------------" echo "pls : http://javame.cnblogs.com welcome" echo "----------------------------------------" echo " 主机信任 | or | 初始化命令(初始) " echo "tools.sh trust | or | tools.sh command" echo "----------------------------------------" ;;esac 19、终端发送回会话给其他用户 限root用户
echo "输入您想说的话吧：" read spkecho $spk >/dev/stdin >/dev/pts/2
20、某目录下所有文件统一批量修改ip
sed -i "s/10.0.0.1/10.0.1.2/g" `grep "10.0.0.1" -rl /opt/uer/wy`
21、链接数与进程数
#链接数netstat -n | awk '/^tcp/ {++y[$NF]} END {for(w in y) print w, y[w]}'#统计httpd协议连接数进程数ps -ef|grep httpd|wc -lps aux|grep httpd|wc -l#句柄数lsof -n|awk '{print $2}'|sort|uniq -c|sort -nr|more #查看进程占用内存ps aux |awk '($1 ~apache) && ($6>50) {print $0}' 22、Linux查看线程的三种方法
1、top -H手册中说：-H : Threads toggle加上这个选项启动top，top一行显示一个线程。否则，它一行显示一个进程。2、ps xH手册中说：H Show threads as if they were processes这样可以查看所有存在的线程。3、ps -mp手册中说：m Show threads after processes这样可以查看一个进程起的线程数。
23、查看连接某服务端口最多的的IP地址
netstat -nat | grep "192.168.1.20:8443" |awk '{print $5}'|awk -F: '{print $4}'|sort|uniq -c|sort -nr|head -20 24、常见压缩解压命名
.tar 解包：tar xvf FileName.tar打包：tar cvf FileName.tar DirName（注：tar是打包，不是压缩！）.gz解压1：gunzip FileName.gz解压2：gzip -d FileName.gz压缩：gzip FileName.tar.gz 和 .tgz解压：tar zxvf FileName.tar.gz压缩：tar zcvf FileName.tar.gz DirName.bz2解压1：bzip2 -d FileName.bz2解压2：bunzip2 FileName.bz2压缩： bzip2 -z FileName.tar.bz2解压：tar jxvf FileName.tar.bz2压缩：tar jcvf FileName.tar.bz2 DirName.bz解压1：bzip2 -d FileName.bz解压2：bunzip2 FileName.bz压缩：未知.tar.bz解压：tar jxvf FileName.tar.bz压缩：未知.Z解压：uncompress FileName.Z压缩：compress FileName.tar.Z解压：tar Zxvf FileName.tar.Z压缩：tar Zcvf FileName.tar.Z DirName.zip解压：unzip FileName.zip压缩：zip FileName.zip DirName.rar解压：rar x FileName.rar压缩：rar a FileName.rar DirName

df -h /root
26.软连接、硬链接
ln -s /home /root/homeln -b /home/run.sh /root/run.sh
27.解压到指定目录
tar zxvf /filename.tar.zip -C /home
28.vi文书
gg第一行G最后一行d1G删除光标所在行到第一行dG删除光标所在行到最后一行yy复制光标所在一行A在光标所在最后字符处开始插入ZZ保存退出
