Need shell script to append double quotes for each column in a file
Hi Experts,

I am beginner to the shell scripting, My requirement is to append double quotes for each column in a file if double quotes does not exist.


Example:

Code:
"abc"|123|"gh-ch"|23.067

Code:
awk '{for (i=1; i<=NF; i++) {sub("^\"", "", $i); sub("\"$", "", $i); gsub("\"", "\\\"", $i); $i="\"" $i "\""} ; print}' FS="|" OFS="|" infile

Try:
Code:
sed 's/"*\([^|"]*\)"*/"\1"/g' file

or
Code:
awk '{for(i=1; i<=NF; i++) gsub(/^"*|"*$/,"\"",$i)}1' FS=\| OFS=\| file

Thanks for the answers!!

But i am having problem with the first column, my file looks like below example.

Code:
"G|||ABCD|||1234"|"ABC"|123.05|"xyz"

except first column i have to apply the above code( as in first column data itself contains pipe(|) in the data)

so when i use above commands the first column pipes are replacing with the double quotes

Code:
"G"|"|"|"ABCD"|"|"|"1234"|"ABC

So i need output like
Code:
"G|||ABCD|||1234"|"ABC"|"123.05"|"XYZ"

Thanks everyone

In that case see if this works:
Code:
awk '{for(i=1; i<=NF; i+=2) gsub(/[^|]+/,"\"&\"",$i)}1' FS=\" OFS=\" file

Hi,
I think this one with sed is ok.
Code:
sed 's/^/"/;s/\([^|]\)\([|]\)\([^|]\)/\1"\2"\3/g;s/$/"/;s/""/"/g' infile

I don't understand this one from Scrutinizer in #3
Code:
sed 's/"*\([^|"]*\)"*/"\1"/g' infile

Someone can explain ?
Thanks.

That replaces any substring NOT containing | nor " , be it enclosed in double quotes or not, with itself enclosed in double quotes. In the requestor's sample line that occurs 4 times.
