常用unix命令

java -cp tools.jar com.tools.fb.tools.redfine.WatchFileChangedTask

一、查询UNIX的大文件

find . -type f -size +100M  （path 为自己指定的目录，如当前目录./）；

按照文件大小排序

du -a /var -h | sort -n -r | head -n 10

不看错误

grep -vP 'No such file or directory'

二、批量删除文件

pgm `autoget paganihost` -v -A "sudo -u admin -H sh -c 'cat /dev/null > /home/admin/pagani/logs/service_stdout.log'"pgm `autoget paganihost` -v -A "sudo -u admin -H sh -c 'rm -rf /home/admin/pagani/logs/service_stdout.log.*'"

三、批量重启机器

1、sudo -u admin -H sh jbossctl restart

2、start | stop | online |offline |pubstart |restart |deploy

/opt/taobao/install

解压

$sudo tar zxvf jdk.tgz -C ./ajdk-8.x

/bin

export JAVA_HOME = /opt/taobao/install/ajdk-8.x/j2sdk-image

export PATH = $JAVA_HOME/bin:$PATH

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

#source /etc/profile
