我正在尝试实现这样的输出

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

我努力了

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

有人可以帮助我达到所需的输出

答案1

另一个awk解决方案。我曾经tr从每一行中删除 CR 字符。整个内容（除了注释#）可能会被压缩成相对难以阅读的单行，但我在这里将其跨几行呈现以帮助提高可读性：

tr -d '\r' <script |
awk -F'[@ ]' '
    # If we have a hostname set, print it and the uptime value; reset for next time
    host && /:/ {printf "%s uptime %s\n", host, $0; host=""}

    # Capture hostname if input matches ">" from the prompt and keyword "uptime"
    !host && />/ && /uptime/ {host=$2}
'

示例的输出

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

答案2

尝试这个：

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-

说明：

  • 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 " "：将重复空格的每个序列仅替换为一个空格
  • grep -Eo 'mike@[^>]+> uptime [0-9]+ days, [0-9]+:[0-9]+': 获取所有-E接受正则表达式的序列 ( ) 并且仅获取它们 ( -o)
  • cut -d "@" -f 2-@: 获取行中第一个 ' ' 字符之后的部分

以你的例子：

> 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
