Question

我有这个文件：

# cat pt_Sed.txt
ULNET-PA,broker_etrade,broker_etrade_uk^M,BR    DELIVERTOCOMPID
ULNET-PA,broker_etrade,broker_etrade_uk^M,CO    TARGETSUBID

我想排列这些线条，使它们看起来像这样：

ULNET-PA,broker_etrade,broker_etrade_uk^M,DELIVERTOCOMPID=BR
ULNET-PA,broker_etrade,broker_etrade_uk^M,TARGETSUBID=CO

我尝试了以下操作，但似乎没有按预期工作：

# x=`awk '{ print $NF }' pt_Sed2.txt`
# echo $x
# DELIVERTOCOMPID
# sed -re "s/\^M,*/&$x=/g" -e 's/ .*//' < pt_Sed.txt
# ULNET-PA,broker_etrade,broker_etrade_uk^M,DELIVERTOCOMPID=BR
# ULNET-PA,broker_etrade,broker_etrade_uk^M,DELIVERTOCOMPID=CO

请您提出解决方案吗？我非常感谢！

谢谢，安德烈

Answer 1

您可以使用awk：

awk -F '[ ,]+' '{$0=$0 "=" $(NF-1); $(NF-1)=""; gsub(/,,/, ",")} 1' OFS=, file

<强>测试

awk -F '[ ,]+' '{$0=$0 "=" $(NF-1); $(NF-1)=""; gsub(/,,/, ",")} 1' OFS=, file | cat -vte
ULNET-PA,broker_etrade,broker_etrade_uk^M,DELIVERTOCOMPID=BR$
ULNET-PA,broker_etrade,broker_etrade_uk^M,TARGETSUBID=CO$

Answer 2

这是一个sed版本：

sed 's/\(.*,\)\([^[:space:]]*\)[[:space:]]*\(.*\)/\1\3=\2/' pt_Sed.txt

Answer 3

$ sed -r 's/,([^[:space:],]+)[[:space:]]+(.*)/,\2=\1/' file
ULNET-PA,broker_etrade,broker_etrade_uk^M,DELIVERTOCOMPID=BR
ULNET-PA,broker_etrade,broker_etrade_uk^M,TARGETSUBID=CO
