解析shell脚本中的文本文件

我想读取一个文件并使用shellscript将其打印到stdout.在python rsplit可以完成这项工作但我搜索并找到awk但我无法理解.

文件1:

#begin cow
Host cow
    HostName 172.18.0.10
    User root
    Port 22
#end cow
#begin dns2
Host dns2
    HostName 172.20.4.80
    User root
    Port 22
#end dns2
#begin dns1
Host dns1
    HostName 172.20.4.75
    User root
    Port 22
#end dns1
#begin dns3
Host dns3
        HostName 172.20.4.76
        User root
        Port 22
#end dns3
#begin dns4
Host dns4
        HostName 172.20.4.77
        User root
        Port 22
#end dns4
#begin dns5
Host dns5
        HostName 172.20.4.78
        User root
        Port 22
#end dns5
#begin dns6
Host dns6
        HostName 172.20.4.79
        User root
        Port 22
#end dns6

解析后转向

Host: cow  Hostname: 172.18.0.10 User: root Port: 22
Host: dns2 Hostname: 172.20.4.80 User: root Port: 22
Host: dns1 Hostname: 172.20.4.75 User: root Port: 22
Host: dns3 Hostname: 172.20.4.76 User: root Port: 22
Host: dns4 Hostname: 172.20.4.77 User: root Port: 22
Host: dns5 Hostname: 172.20.4.78 User: root Port: 22
Host: dns6 Hostname: 172.20.4.79 User: root Port: 22

任何人都可以帮助我,谢谢你

由于您未awk在问题中提及您的命令,我假设您正在寻找解决方案awk和解释.

AMD$ awk '!/^#/{printf $1": "$2" "}/end/{print '\n'}' File

Host: cow HostName: 172.18.0.10 User: root Port: 22
Host: dns2 HostName: 172.20.4.80 User: root Port: 22
Host: dns1 HostName: 172.20.4.75 User: root Port: 22
Host: dns3 HostName: 172.20.4.76 User: root Port: 22
Host: dns4 HostName: 172.20.4.77 User: root Port: 22
Host: dns5 HostName: 172.20.4.78 User: root Port: 22
Host: dns6 HostName: 172.20.4.79 User: root Port: 22

对于NOT以#(!/^#/)开头的所有行,print 1st和2nd由:和分隔的字段和字段space.继续这个直到我们点击end模式(/end/),我们将打印新行.

如果您正在寻找awk已有命令的解释,请在问题中提及.
