小编tid*_*ake的帖子

我有几个别名我想澄清一下。他们在工作。我怎样才能使它成为许多其他别名的选项。awk 还是 grep？和指针有帮助。谢谢。

# IP addresses
alias myip="echo  '# myip  curl https://ipecho.net/plain; echo #'; curl -sS https://ipecho.net/plain; echo"
alias hazip="echo '# hazip curl https://ipv4.icanhazip.com     #'; curl -sS https://ipv4.icanhazip.com"
alias ips='myip && hazip'

 ~ ips
# myip  curl https://ipecho.net/plain; echo #
1.2.3.4
# hazip curl https://ipv4.icanhazip.com     #
1.2.3.4

我对这些结果感到困惑。我该如何修复这些警报？这对于使用 Ubuntu 的家用计算机来说是否正常？谢谢。
