如何刪除標題，換行符\\和“”

Question

我有數據文件：

"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，預期的輸出是：

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

不同之處在於：

1. 不應有標題行
2. 每行的開頭和結尾都不應包含“”
3. 轉義的換行符（反斜杠后跟換行符）不應出現

如何獲得我的要求？

Answer 1

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

可以將其粉碎成一條難以理解的行，但是當它們整齊地分開時，更容易解釋這五個操作：

1. 如果該行以反斜杠結尾，則將下一行連接到緩沖區（模式空間）並重新啟動。
2. 用空格替換任何反斜杠換行符。
3. 刪除行首的雙引號。
4. 刪除行尾的雙引號。
5. 刪除任何不以數字開頭的行。

給定輸入的干凈版本（無尾隨空格），將產生：

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

這應該可以解決問題：

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

輸出：

$ cat file
"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"

Answer 3

在vim中打開這個，執行這個

:%s/^"//g

:%s/"$//g

:%s/\\//g

但我還不知道如何識別標題
