Adding field to file and moving the last 2 fields
I have a file with 32 fields each separated by ‘|”. I need to add a file date exactly in the format “ "20100120" “ as the 32nd field moving the existing 32nd field to 33. so the field I added should be 32nd and the 33rd field is the last field before I added the file date.

I know we can use sed and awk to replace or add for a file either at beginning or the end but not in the last but one position. Is there a way to do this?

Code:
sed "s/|\([^|]*\)$/|20100120|\1/" file

Code:
awk -F"|" -v OFS="|" ' { $(NF+1)=$NF; $(NF-1)="20100120" ; print } ' file

Code:
file_DATE=$(date +'%Y%m%d')
sed "s/|\([^|]*\)$/|$file_DATE|\1/" file

Code:
file_DATE=$(date +'%Y%m%d')
awk -F"|" -v OFS="|" -v dt=$file_DATE ' { $(NF+1)=$NF; $(NF-1)=dt ; print } ' file

Code:
file_DATE=$(date +'%Y%m%d')
awk -F"|" -v OFS="|" ' { $(NF+1)=$NF; $(NF-1)="'"$file_DATE"'" ; print } ' file
