Linux 常用脚本
1ch0 script
1. 配置查询
# 查看 cpu 配置
cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
cat /proc/cpuinfo |grep "physical id"|sort|uniq|wc -l
cat /proc/cpuinfo |grep "cpu cores"|wc -l
# pv page view
cat /var/log/httpd/access_log|wc -l
sort -t: -k3 /etc/passwd
分区磁盘占用最大值
df | tr -s ' ' %| cut -d% -f5 | sort -nr| head -n1查看连接数
last|tr -s ' '|cut -d ' ' -f3|sort|uniq -c|sort -n -r lastb|tr -s ' '|cut -d ' ' -f3|sort|uniq -c|sort -n -r lastb|tr -s ' '|cut -d ' ' -f3|sort|uniq -c|sort -n -r|tr -s ' '|cut -d ' ' -f3 vim /etc/hosts.deny sshd: 120.246.107.20cut

2. 批量执行
2.1批量执行命令
2.1.1 expect
#!/bin/bash
cat iplist|while read line #iplist文件中存放了IP地址和密码，每行格式为“IP地址 密码”
do
a=($line)
/usr/bin/expect <<EOF
spawn ssh root@${a[0]}
expect {
"*yes/no" { send "yes\r"; exp_continue}
"*password:" { send "${a[1]}\r" }
}
expect "#"
send "whoami\r"
send "ip add\r"
send "exit\r"
expect eof
EOF
done
