Question

我的数据文件为：

"S.ACQUIRER||'|'||SUBSTR(S.ACQ_COUNTRY,1,4)||'|'||SUBSTR(S.ACQ_CURRENCY_CODE,1,5)||'|'||S.PAN||'|'||SUBSTR(S.ACCTNUM,1,18)||'|'||SU\    BSTR(I.E_NAME,1,35)||'|'||S.LOCAL_DATE||'|'||S.LOCAL_TIME||'|'||DECODE(S.PCODE,0,'POSTRANSACTIONFROMDEFAULTACCOUNT',1000,'POS"
"9000000007|840|840|5048349120900000008|504834000000006028|Ecustomer name |03-JAN-14|115744|Cash Withdrawal from\
Savings Account |10|Approved |2000061|ATM Test Terminal Bang |123400000123456 |01001101"
"9000000007|840|840|5048349120900000008|504834000000006028|Ecustomer name |03-JAN-14|115744|Cash Withdrawal from\
Savings Account |10|10|4000061|ATM Test Terminal Bang |123450000000456 |01001101"

但是，预期的输出是：

9000000007|840|840|5048349120900000008|504834000000006028|Ecustomer name |03-JAN-14|115744|Cash Withdrawal from Savings Account |10|Approved |2000061|ATM Test Terminal Bang |123400000123456 |01001101
9000000007|840|840|5048349120900000008|504834000000006028|Ecustomer name |03-JAN-14|115744|Cash Withdrawal from Savings Account |10|10|4000061|ATM Test Terminal Bang |123450000000456 |01001101

区别在于：

应该没有标题行
不应该＆＃34;＆＃34;在开始每一行和结束时
转义的新行字符（反斜杠后跟换行符）不应出现

如何满足我的要求？

Answer 1

sed -e '/\\$/N' \
    -e 's/\\\n/ /g' \
    -e 's/^"//' \
    -e 's/"$//' \
    -e '/^[^0-9]/d' \
    "$@"

这可能会被压成一条不可读的线，但是当它们整齐地分开时，更容易解释这五个操作：

如果该行以反斜杠结尾，请将下一行连接到缓冲区（模式空间）并重新启动。
用空格替换任何反斜杠换行符。
删除行首的双引号。
删除行尾的双引号。
删除任何不以数字开头的行。

给定一个干净的输入版本（没有尾随空白），这会产生：

9000000007|840|840|5048349120900000008|504834000000006028|Ecustomer name |03-JAN-14|115744|Cash Withdrawal from Savings Account |10|Approved |2000061|ATM Test Terminal Bang |123400000123456 |01001101

Answer 2

这应该可以解决问题：

awk '/\\$/&&NR>2{sub(/\"/,"");printf $0;next}NR>2{sub(/\"/,"");print}' file

<强>输出：

$ cat file
