我正在尝试编写一个脚本来连接到远程服务器，ping 其他服务器(IP 作为参数)并输出结果。
所以这是我写的:
#!/bin/bash
# IP as argument
IP=$1
# Remote connection
ssh -p 22 <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="384851565f5d4a784c5d4b4c5d4a1655414b5d4a4e5d4a165b5755" rel="noreferrer noopener nofollow">[email protected]</a>
# Pinging and saving only latency results to RESULT
RESULT=`ping -i 2 -c 4 $IP | grep icmp_seq | awk '{print $7}' | cut -b 6-12`
# Outputs the result
echo $RESULT
但是我收到错误:
Name or service not known name tester.myserver.com
当然 tester.myserver.com 只是示例，但如果我使用真实的远程服务器地址手动键入 ssh 命令，它确实可以工作。所以我真的不知道为什么这不能作为脚本使用。
最佳答案
将相应的行更改为:
RESULT=`ssh <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="b5c5dcdbd2d0c7f5c1d0c6c1d0c79bd8ccc6d0c7c3d0c79bd6dad8" rel="noreferrer noopener nofollow">[email protected]</a> "ping -i 2 -c 4 ${IP}" | grep icmp_seq | awk '{print $7}' | cut -b 6-12`
或者不使用 awk:
RESULT=`ssh <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c2b2abaca5a7b082b6a7b1b6a7b0ecafbbb1a7b0b4a7b0eca1adaf" rel="noreferrer noopener nofollow">[email protected]</a> "ping -i 2 -c 4 ${IP} | grep icmp_seq | sed 's/^.*time=\([0-9.]\+\).*/\1/'"`
