从一行中获取一件事并将其与另一行中的一件事连接起来

Question

我有以下几点：

2018-11-10 23:57:21 [COMMAND]: sar -u 10 5

AIX host 1 7    11/10/18

System configuration: lcpu=64  mode=Capped

23:57:21    %usr    %sys    %wio   %idle   physc
23:57:31      10       7       0      83   16.00
23:57:41       9       6       0      85   16.00
23:57:51       9       6       0      85   16.00
23:58:01       9       7       0      84   16.00
23:58:11      10       6       0      84   16.00

Average        9       6       0      84   16.00

2018-11-10 23:58:21 [COMMAND]: sar -u 10 5

AIX host 1 7    11/10/18

System configuration: lcpu=64  mode=Capped

23:58:21    %usr    %sys    %wio   %idle   physc
23:58:31      10       8       0      82   15.99
23:58:41       9       6       0      85   16.00
23:58:51       9       6       0      85   16.00
23:59:01       9       6       0      84   16.00
23:59:11      10       6       0      83   16.00

Average       10       6       0      84   16.00

我需要获得平均值的时间%idle：

2018-11-10 23:57:21|84
2018-11-10 23:58:21|84

Answer 1

按原样查看输入文件，awk如下所示的简单命令就足够了。

awk '/sar/{ time=$1" "$2; next }/Average/{ print time"|"$5 }' file

Answer 2

几个选择：

• awk

  $ awk '/COMMAND/{printf "%s %s", $1,$2}/Average/{print "|"$5}' file 
  2018-11-10 23:57:21|84
  2018-11-10 23:58:21|84
  

• perl

  $ perl -ale '$k="$F[0] $F[1]" if /COMMAND/; print "$k|$F[4]" if /Average/' file
