从txt文件中删除双引号

Question

I have a file that contains unwanted double quotes around the column values. I need to remove them. Could someone help me on this?

The data is in below format

column1 date picture value "A" "2016-06-02" "books" 932422 "B" "2016-06-03" "movies" 934735 "C" "2016-06-04" "vidoes" 936025 "D" "2016-06-05" "movies" 937620 "E" "2016-06-06" "dvd" 938972 "F" "2016-06-07" "vidoes" 940274

And I want to the data to be like:

column1 date picture value A 2016-06-02 books 932422 B 2016-06-03 movies 934735 C 2016-06-04 vidoes 936025 D 2016-06-05 movies 937620 E 2016-06-06 dvd 938972 F 2016-06-07 vidoes 940274

Note that 4th column attribute do not have double quotes around them.

Could somebody help me with removing these double quotes with one line shell scripting?

Or using awk :

awk -F\" '{$1=$1}1' infile

 F      2016-06-07      vidoes      940274

or using sed :

 sed 's/"//g' infile

F    2016-06-07    vidoes     940274

or using awk 's gsub function:

awk '{gsub(/"/,"")}1' infile

Answer 2

如果可以使用sed，

$ sed 's/\"//g' file.txt > file_new.txt

Answer 3

Just use the below command and run it on the file. The file gets modified automatically. No need for a temporary file for redirection.

 perl -pi -e 's/\"//g' infile
