awk将时间转换为毫秒：

#!/bin/bash
if [ $# -lt 1 ]; then
    echo "usage: $0 filename"
    exit 1
fi

grep ":" ca_server.log  | \
   sed 's/\t/ /g' | \
   awk -F' ' 'BEGIN{OFS=",";} {print $1,$3,$6}'  | \
   awk -F'[.:]' 'BEGIN{OFS=",";} {tm=(((($1*60)+$2)*60+$3)*1000)+$4; print $0,tm}' | \
   awk -F',' 'BEGIN{OFS=",";} {print $2,$1,$4,$3}' \
   > $1"_cleanup.csv"

转换前：

当前时间                当前时间                交易所时间           最新价             成交量             成交额
