awk打印$ 0打印我文件的所有行到列的最后位置;我怎么能先打印？

Question

我使用此命令

  awk -F";" '{ print $0 "VVVVVVVV" $10 }' FILE3.csv

此打印效果不错，但按此顺序打印

VVVVVVVV; column10;的列1;列2;栏3：column4; column5 ..... column10

我需要反向打印 的列1;列2;栏3：column4; column5 ..... column10 ; VVVVVVVV; column10

但是我的工作怎么办？

Answer 1

要么

$ awk -F";" '{ sub("\r",""); print $0 "VVVVVVVV" $10 }' file

或

$ awk -F";" '{ print $0 "VVVVVVVV" $10 }' RS="\r\n" file

或

$ dos2unix file
$ awk -F";" '{ print $0 "VVVVVVVV" $10 }' file

以下是示例

akshay@db-3325:/tmp$ cat file
column1;column2;column3;column4;column5;column6;column7;column8;column9;column10
column1;column2;column3;column4;column5;column6;column7;column8;column9;column10

# See at the end there is ^M char
akshay@db-3325:/tmp$ cat -A file
column1;column2;column3;column4;column5;column6;column7;column8;column9;column10^M$
column1;column2;column3;column4;column5;column6;column7;column8;column9;column10^M$

# Using awk without sub() - This is what you got
akshay@db-3325:/tmp$ awk -F";" '{ print $0 "VVVVVVVV" $10 }' file
VVVVVVVVcolumn10column3;column4;column5;column6;column7;column8;column9;column10
VVVVVVVVcolumn10column3;column4;column5;column6;column7;column8;column9;column10

# Using awk with sub() - This is what you wanted to get
akshay@db-3325:/tmp$ awk -F";" '{ sub("\r",""); print $0 "VVVVVVVV" $10 }' file
column1;column2;column3;column4;column5;column6;column7;column8;column9;column10VVVVVVVVcolumn10
column1;column2;column3;column4;column5;column6;column7;column8;column9;column10VVVVVVVVcolumn10

akshay@db-3325:/tmp$ awk -F";" '{ print $0 "VVVVVVVV" $10 }' RS="\r\n" file
column1;column2;column3;column4;column5;column6;column7;column8;column9;column10VVVVVVVVcolumn10
column1;column2;column3;column4;column5;column6;column7;column8;column9;column10VVVVVVVVcolumn10

# dos2unix
akshay@db-3325:/tmp$ dos2unix file
dos2unix: converting file file to Unix format ...

# Now you can see ^M is not there
akshay@db-3325:/tmp$ cat -A file
column1;column2;column3;column4;column5;column6;column7;column8;column9;column10$
column1;column2;column3;column4;column5;column6;column7;column8;column9;column10$

# Now your awk 
akshay@db-3325:/tmp$ awk -F";" '{ print $0 "VVVVVVVV" $10 }' file
column1;column2;column3;column4;column5;column6;column7;column8;column9;column10VVVVVVVVcolumn10
