我在下面用逗号分隔了两列：
"01962424813","KSDP01"
"KSDP01","01962424813"
"8801962424813","KSDP01"

每当我在第一列中找到子串19时，我想交换这两个值。我怎样才能做到这一点？这是我尝试过的：
awk -F, 'BEGIN{OFS=","}{$1=$1;if( awk '$1 ~ /19/' ){print $2,$1}else{print $1,$2}}'
答案 0 :(得分：1)
awk -v FS="," -v OFS="," '($1 ~ /19/){temp=$1;$1=$2;$2=temp}1' filename
应该这样做。以下是示例输出
"KSDP01","01962424813"
"KSDP01","01962424813"
"KSDP01","8801962424813"
