How to cut (select) a field from text line counting from the end?

Reverse the input before and after cut with rev:

<infile rev | cut -d, -f2 | rev

Output:

d
i
n

Try doing this with awk :

awk -F, '{print $(NF-1)}' file.txt

Or using perl :

perl -F, -lane 'print $F[-2]' file.txt

Or using ruby (thanks manatwork) :

ruby -F, -lane 'print $F[-2]' file.txt

Or using bash (thanks manatwork) :

while IFS=, read -ra d; do echo "${d[-2]}"; done < file.txt

Or using python :

cat file.txt |
python -c $'import sys\nfor line in sys.stdin:\tprint(line.split(",")[-2])'
