awk打印行與n列，並忽略最後一行

-1

我想在awk中得到更好，並使用它的一些CSV格式的文件，它有多個標題行與n行後實際報告開始。該報告還有一個需要丟棄的頁腳。以下是我想結合條件生成一個乾淨的報告awk打印行與n列，並忽略最後一行

awk -F, '{NF==25} END {NR>2 {print l} {l=$0}}' 6999_RACV_Master_Conversion_Report_csv_20171005_114903_618978908.csv > 6999_RACV_Master_Conversion_Report_csv_20171005_114903_618978908_formatted.csv

與上述我能夠擺脫頁腳，但標題存在。這裏是興田樣本數據

請表明樣品輸入和預期輸出 –

除了Akshay要求發佈樣本數據（您應該將代碼標籤放入您的文章中）之外，我注意到END塊中的條件NR> 2對於所有行都無法正常工作，因爲END一旦完成讀取Input_file的所有行，就會出現awk部分。 – RavinderSingh13

感謝您添加示例輸入，期望的輸出是什麼，請在代碼標記中添加 – RavinderSingh13

既然你還沒有表現出我們的樣本數據和樣本預期的輸出，所以根據您的說法和假設喜歡你的頭是上非常第一行，你的頁腳在你的Input_file的最後一行之後可能會幫助你。比方說，下面是INPUT_FILE：

cat file_test 
My header 
bla bla bla bla data data data 
bla bla bla bla

所以，以下是它會跳過第1行和最後一行（分別爲頁眉和頁腳）的代碼。

awk -v lines=$(wc -l < file_test) 'NR>1 && NR<lines' file_test 
bla bla bla bla data data data 
bla bla bla bla

PS：如果你有一些其他的要求，然後親切地張貼樣品INPUT_FILE在您的文章預期產出太代碼標記。

通常在進行downvoting時發表評論。（這不是與downvote相關的評論:) –

我認爲有人低估了，因爲你（我們）回答了一個未完成的問題。我也可能與您的輸出相關，而不是反映最後一條記錄未打印。 –

@JamesBrown，同意，謝謝先生。 – RavinderSingh13

用awk就可以開始print從記錄NR>ň荷蘭國際集團，但你必須要提供的記錄數，如果你想以後一定的記錄停止print ING。另一種方法是將最後的記錄保存在緩衝區中（如之前的所示，只有一個記錄緩衝區p）。但首先一些測試文件：

$ cat file 
head1  # unwanted 
head2  # wanted 
record1 # wanted 
record2 # wanted 
footer  # unwanted

然後用其輸出的腳本：

$ awk 'NR>2{print p}{p=$1}' file 
head2 
record1 
record2

編輯：

與特定數據（與記錄分割和所有），使用此：

$ awk 'NR>=34{print p}{p=$0}' file

這是另一個想法sed，

sed -n '/Report Fields/,$!b;//d;$!p' file

簡要說明，

/Report Fields/,$ !b：跳過腳本如果行不「報告字段」中的最後一行
//d範圍：刪除該行包含「Report Fields」
$!p：打印除最後一行之外的其餘行

對於給定的輸入，下面一個應該工作

awk 'f{sub(/^[ \t]+/,"")}f && !/Grand/; /Report Fields/{f=1}' infile

甚至

awk 'f && sub(/^[ \t]+/,""); /Report Fields/{f=1}' infile

說明：

/Report Fields/{f=1}如果AWK找到具有圖案線，設置變量f=1
f{sub(/^[ \t]+/,"")}如果設置了變量f，則禁止行開始處的空格製表符字符。
f && !/Grand/;如果變量f被設置，並且行不包含Grand那麼打印這樣的行。
f && sub(/^[ \t]+/,"");如果變量f被設置，sub()返回布爾真值，然後打印這樣的行/記錄（因此與Grand Total:該線將被跳過，因爲線不匹配/^[ \t]+/）

awk打印行與n列，並忽略最後一行
