調試 Ping 腳本
我之前請求過一個 ping 腳本的幫助,該腳本應該 ping 一些主機,如果任何 ping 失敗,請給我發電子郵件。這工作正常。
現在我想修改那個腳本(見下文),如果它成功了,它就會給我發電子郵件。所以基本上我希望腳本 ping 幾個我知道它們沒有啟動的主機,如果這些主機中的任何一個返回 ping,那麼我希望腳本通過電子郵件發送給我。這是我目前擁有的腳本:
#!/bin/bash ping_targets="server1 server2 server3 server4 server5" failed_hosts="" for i in $ping_targets do ping -c 1 $i > /dev/null if [ $? -ne 0 ]; then if [ "$failed_hosts" == "" ]; then failed_hosts="$i" else failed_hosts="$failed_hosts, $i" fi fi done if [ "$failed_hosts" != "" ]; then echo $failed_hosts| mailx -s "Failed ping targets" email@domain fi
#!/bin/bash ping_targets="server1 server2 server3 server4 server5" for i in $ping_targets do ping -c 1 $i > /dev/null if [ $? -eq 0 ]; then echo "$i ping success!" > test_file fi if [ -s test_file ];then mailx -s "Successful ping targets" -a test_file email@domain fi
如果您不想添加附件,請將
mailx
line 替換為:mailx -s "Successful ping targets" email@domain < test_file
ping_targets="server1 server2 server3 server4 server5" up_hosts="" for i in $ping_targets do ping -c 1 $i > /dev/null if [ $? -eq 0 ]; then if [ "$up_hosts" == "" ]; then up_hosts="$i" else up_hosts="$up_hosts, $i" fi fi done if [ "$up_hosts" != "" ]; then echo $up_hosts| mailx -s "ping targets that are now available" email@domain fi
