Dojo: Pull the Last Column
EasyOne-Liner Dojo5 minThe brief
The CSV /root/records.csv has a varying number of comma-separated columns per line, but you only want the LAST field of each. In ONE line, write those last fields (one per line, same order) to /root/answer.txt.
cut can't easily grab 'the last one' when the column count varies — but awk knows the last field by name. Find it.
What you'll do
- Write the last comma-separated field of each line of /root/records.csv to /root/answer.txt, in one line
