File formating help
Hi all,

I am having the file below

Quote:
"NOT APPLICABLE","0000103","NOT APPLICABLE","Y"
"NOT APPLICABLE","0000109","NOT APPLICABLE","Y"
"NOT APPLICABLE","0005004","NOT APPLICABLE","Y"
"NOT APPLICABLE","0000001","NOT APPLICABLE","Y"
"NOT APPLICABLE","0000002","NOT APPLICABLE","Y"
I need that as below

"NOT APPLICABLE","0000109","1","Y"
"NOT APPLICABLE","0005004","1","Y"

I've noticed there're a number of awk-based proposed solutions posted for your 336 posts.
Could you try something with awk and see how far you get, please!

Able to extract the value using AWK but not able to replace that in the file

Code:
awk -F, '{print $3=1}' FSDS.CSVX

Below also not working
Code:
 awk 'BEGIN{OFS=FS=","}$3=="NOT APPLICABLE"{$3=1}{print}' file
 awk -F "|" '{ if ( $3 =="NOT APPLICABLE" ) print $1"|"$2"|"1"|$4' file

Files do not work that way. You can't write to the same file you're reading from. A few commands can pretend, but they're really using temp or whole-memory buffers files like everything else does:
Code:
awk ... filename > /tmp/$$
# BACK UP YOUR DATA before doing this!  One mistake and filename's contents are blown away
cat /tmp/$$ > filename
rm -f /tmp/$$

awk doesn't provide the facility to edit "in-place". redirect to a temp file and then mv.
Make sure you provide a correct field separator.
