winavr util妙用

minicore

WinAVR-20080610.exe 不仅是一个WinAVR的编译器，同时支持许多Linux命令的Win32版！

cat.exe
ls.exe
grep.exe
gawk.exe
etc..

经测试，很不错！ 下面给出一些例子

gawk exsample:

输入文件内容如下：
input.txt

Timestep at 0
[Exp.Dist] t1 8
Timestep at 1
[Exp.Dist] t1 2
Timestep at 2
[Exp.Dist] t1 7
Timestep at 3
Delayed transition t1 fired at time 4
[Exp.Dist] t1 0
Timestep at 4
Delayed transition t1 fired at time 5
[Exp.Dist] t1 10
Timestep at 5
[Exp.Dist] t1 9
Timestep at 6
[Exp.Dist] t1 1
Timestep at 7
Delayed transition t1 fired at time 8
[Exp.Dist] t1 2
Timestep at 8
Delayed transition t1 fired at time 9
[Exp.Dist] t1 0
Timestep at 9
Delayed transition t1 fired at time 10
Delayed transition t1 fired at time 10
Delayed transition t1 fired at time 10
[Exp.Dist] t1 19
Timestep at 10
[Exp.Dist] t1 9
Timestep at 11
[Exp.Dist] t1 18
Timestep at 12
[Exp.Dist] t1 8
Timestep at 13
[Exp.Dist] t1 26
Timestep at 14
Delayed transition t1 fired at time 15
Delayed transition t1 fired at time 15

要求把以[Exp.Dist]开头的行过滤数来，同时打印如下:  t1 8

所用命令如下：

gawk '/^\[Exp.Dist\]/ {print $2 " " $3}' input.txt > output.txt
