linux下批量并行telnet对端端口的实现方法(linux批量处理文件)

编辑：rootadmin

以下是以telnet对端端口为例 station:~/shell/telnet_port # pwd /root/shell/telnet_port station:~/shell/telnet_port # cat telnet_port.sh #!/bin/bash rm telnet_result.txt >/dev/null 2>&1 PORT_= for i in $(cat ip.list) do (telnet $i $PORT_<<EOF>>telnet_result.txt &) >/dev/null 2>&1 #加&让其并行执行,>>telnet_result.txt记录telnet过程中的日志 quit EOF done cat telnet_result.txt | grep -B 1 ] | grep [1-9] | awk '{print $3}' | cut -d '.' -f 1,2,3,4 > telnet_alive.txt cat ip.list telnet_alive.txt | sort | uniq -u > telnet_die.txt station:~/shell/telnet_port # for i in {..};do echo "...$i">>ip.list;done #使用for循环得到需要telnet主机的ip station:~/shell/telnet_port # cat ip.list ... ... ... ... ... ... station:~/shell/telnet_port # ls ip.list telnet_port.sh station:~/shell/telnet_port # ./telnet_port.sh & [1] station:~/shell/telnet_port # ls ip.list telnet_alive.txt telnet_die.txt telnet_port.sh telnet_result.txt [1]+ Done ./telnet_port.sh station:~/shell/telnet_port # cat telnet_alive.txt //从本机telnet对端端口能telnet通的只有... ... station:~/shell/telnet_port # cat telnet_die.txt ... ... ... ... ... station:~/shell/telnet_port # cat telnet_result.txt //记录的日志格式 Trying ...... Connected to .... Escape character is '^]'. Trying ...... Trying ...... Trying ...... Trying ...... Trying ......
