我们如何提取此文件的两个第一列，即字段user和ip address，以便输出如下所示：

user4  1x3.xxx.126.xx
useral 7x.xx.xxx.1xx 
userxxxx x7.xx5.xx.1x1 
someuse 9x.8x.xx0.xx4  
nameuse x8.xx3.6x.7x
blabl xx.2xx.x.x4    
aaaaaa xx9.x3.4x.2x

Answer 1

BEGIN { FS = "|" }

/Last used share/ { next }

{ if(NF == 11) print $2, $3 }

更新：操作说明......

$ awk -f test.awk < cam.txt
user4        1x3.xxx.126.xx 
useral       7x.xx.xxx.1xx  
userxxxx     x7.xx5.xx.1x1  
someuse      9x.8x.xx0.xx4  
nameuse      x8.xx3.6x.7x   
blabl        xx.2xx.x.x4    
aaaaaa       xx9.x3.4x.2x

或者，someprogram | awk -f test.awk

Answer 2

我建议应用问题答案中开发的技术＆＃34; How to parse rackspace big data api response using shell scripting“。在您的特殊情况下，这会产生：

# ccam_canonize
#  Canonize output of ccam report tools
ccam_canonize()
{
  sed -e '1,3d;/^+[-+]*$/d;s/^| //;s/ |$//;s/ | /|/g;/Shareinfo/,$d'
}

# ccam_extract
#  Extract user and IP
ccam_extract()
{
  awk -F'|' '{print($1,$2)}'
}

ccam_canonize | ccam_extract
