CSV file REPLACE COLUMN if it matches
I have a file
Code:
cat 1.txt
AAAA , BBBB , CCCC , DDDD
DFDF , DFDF , DFDF , FDDD
AA11 , DFDF , 0000 , UTIO
ADSD , WERT, 0000 , JKJL

If the 3rd column is not equal to "0000" , then it should replace "0000" with "XXXX" and if its equal to "0000" then print the line as it is.

need help.

Following may help you in your requirement.

Code:
awk -F"," '($3 !~ 0) {gsub(/.*/," XXXX ",$3);} 1' OFS=","   filename

Output will be as follows.

Code:
AAAA , BBBB , XXXX , DDDD

Code:
awk -F '[ ]*,[ ]*' '$3 != "0000" {$3="XXXX"}1' OFS=, file

If you want spaces before and after ,
Code:
awk -F '[ ]*,[ ]*' '$3 != "0000" {$3="XXXX"}1' OFS=' , ' file

Hi Aravind,

If you are referring to my solution then following may help.

Code:
awk -F"," ' NR>1 && ($3 !~ 0) {gsub(/.*/," XXXX ",$3);} 1' OFS=","   filename

if you are reffering to Srini's solution then kindly add NR>1 in the starting of the solution.


Thanks,
R. Singh
