部分匹配大小写

Question

下面有两列，用逗号隔开：

"01962424813","KSDP01"
"KSDP01","01962424813"
"8801962424813","KSDP01"
01962424813,KSDP01
1962424813,KSDP01
8801962424813,KSDP01
KSDP01,01962424813
KSDP01,1962424813
KSDP01,8801962424813
"1962424813","KSDP01"
"KSDP01","1962424813"
"KSDP01","8801962424813"
01959969994,ASDP11
"8801962424183","ASDP01"
"801962424183","KSDP11"
"01962424183","CSDP10"
"1962424183","ASDP09"
8801962424183,CSDP13
801962424183,KSDP08
01962424183,ASDP07
1962424183,CSDP05
"ASDP01","8801962424183",
"KSDP11","801962424183",
"CSDP10","01962424183"
"ASDP09","1962424183"
CSDP13,8801962424183
KSDP08,801962424183
ASDP07,01962424183
CSDP05,1962424183
01912401927,CSDP06

每当我在第一列中找到子字符串19时，我都想交换这两个值。我该怎么做呢？这是我尝试过的：

awk -F, 'BEGIN{OFS=","}{$1=$1;if( awk '$1 ~ /19/' ){print $2,$1}else{print $1,$2}}'
