^M我正试图实现这样的输出
grv1.nue99.de> uptime 9 days, 3:43
grv2.nue99.de> uptime 10 days, 3:43
grv1.nue98.de> uptime 11 days, 3:43
grv2.nue98.de> uptime 12 days, 3:43我试过了
awk '/mike@.*> uptime/ {print;getline;print}' testbeta1.text > testbeta2.txt
sed 's/mike@//g; s/> uptime/> uptime /g' test.txt > test1.txt
grep -oP 'mike@.*uptime.*\K[0-9]+\sdays.*' testbeta.text有人能帮我达到预期的输出吗？

试试这个：
cat testbeta1.text | tr -d "\r" | tr "\n" " " | tr -s " " | grep -Eo 'mike@[^>]+> uptime [0-9]+ days, [0-9]+:[0-9]+' | cut -d "@" -f 2-解释：
tr -d "\r"：删除所有CR字符tr "\n" " "：将每个LF字符替换为一个空格tr -s " "：仅用一个空格替换重复空间的每个序列grep -Eo 'mike@[^>]+> uptime [0-9]+ days, [0-9]+:[0-9]+'：获取接受正则表达式的所有序列(-E)，并且只接受它们(-o)cut -d "@" -f 2-：在第一个'@‘字符之后获得行的部分
以你为例：
> cat testbeta1.text | tr -d "\r" | tr "\n" " " | tr -s " " | grep -Eo 'mike@[^>]+> uptime [0-9]+ days, [0-9]+:[0-9]+' | cut -d "@" -f 2-
grv1.nue99.de> uptime 9 days, 3:43
grv2.nue99.de> uptime 10 days, 3:43
grv1.nue98.de> uptime 11 days, 3:43
grv2.nue98.de> uptime 12 days, 3:43页面原文内容由Unix & Linux提供。腾讯云小微IT领域专用引擎提供翻译支持
