我有一个 1 班轮，它将 telnet 会话的输出写入文件。
while sleep 5; do sleep 1 | telnet 11.22.33.44 443 | tee -a /var/tmp/test$(date +%Y%m%d).txt && date >> /var/tmp/test$(date +%Y%m%d).txt; done &
我不想看到第一个命令的输出但是想运行这个 1 班轮并显示输出：
awk '!/Trying/{count++}/Trying/{if (count == 4) print "Connected"; else if (count == !NR) print ""; else print "Failed"; count = 0}' test$(date +%Y%m%d).txt
奖金如果！可以在 1 行中同时显示输出，如下所示：
while sleep 5; do sleep 1 | telnet 159.203.162.223 443 | tee -a /var/tmp/test$(date +%Y%m%d).txt && date >> /var/tmp/test$(date +%Y%m%d).txt; done & awk '!/Trying/{count++}/Trying/{if (count == 4) print "Connected"; else if (count == !NR) print ""; else print "Failed"; count = 0}' test$(date +%Y%m%d).txt
