我有一個(gè)日志文件a.log
里面大概內(nèi)容是：
select sum(in_count),sum(out_count) from mid_roam_201607
233 255
select sum(in_count),sum(out_count) from mid_resul_201607
145 288

現(xiàn)在怎么把這4個(gè)值分別提取出來(lái)，放到4個(gè)變量里？

能定位到行嗎？
sed -n '2p' a.log  | awk '{print $1}'
sed -n '2p' a.log  | cut -d" " -f1
類(lèi)似于這樣的，應(yīng)該差不多

v1=`grep -A1 "roam" file | tail -1 | awk '{print $1}'`
v2=`grep -A1 "roam" file | tail -1 | awk '{print $2}'`
v3=`grep -A1 "result" file | tail -1 | awk '{print $1}'`
v4=`grep -A1 "result" file | tail -1 | awk '{print $2}'`

1. eval $(awk '/select/{++i;getline;print "k"i"="$1,"v"i"="$2'} a.log)
   
2. echo "$k1 $v1 $k2 $v2"
