I have a csv input file where I want to extract specific fields. When I cat that file into mawk using the {FS=","} within the brackets, the first line of output is as if the field separator was still a space instead of the comma that I specified. From the second line onwards, the comma field separator is honoured.
The first three lines of output from the command I am using are:
$ cat LUN.csv | awk '{FS=","} {print $2","$5","$14","$17","$20","$23","$26","$29","$32","$35","$77","$78","$79","$80","$81","$82","$83","$84","$85","$86","$87","$88","$89","$90","$91","$92","$93","$94","$95","$96","$97","$98}'
