[SOLVED] How to quote the fields of every row with awk or sed

Issue

I have txt file like below

line1 record1 epm1 FY21 3
line2 record2 epm2 FY21 4 
line3 record3 epm3 FY21 7.23
line4 record4 epm4 FY21 90

I want to get output as below using awk or sed if possible

"line1" "record1" "epm1" "FY21" 3
"line2" "record2" "epm2" "FY21" 4 
"line3" "record3" "epm3" "FY21" 7.23
"line4" "record4" "epm4" "FY21" 90

Thank you for your help

Solution

You may use this sed command:

sed -E 's/([^[:blank:]]*[[:alpha:]][^[:blank:]]*)/"\1"/g' file

Here:

• [^[:blank:]]: Matches a non-whitespace
• [[:alpha:]]: Matched an alphabetic character

"line1" "record1" "epm1" "FY21" 3
"line2" "record2" "epm2" "FY21" 4
"line3" "record3" "epm3" "FY21" 7.23
"line4" "record4" "epm4" "FY21" 90
