Top Forums UNIX for Dummies Questions & Answers Extract a certain field from a CSV? Post 302497197 by chickeneaterguy on Wednesday 16th of February 2011 02:33:39 PM

Thanks, is there a way I could do it with writing:
Code:
awk -F, '{(if $2 == 1940) print $3}' > gender.txt

note: I'd be writing this into a file/script then running it as a parameter. Say the above code is titled genderExtract.sh, could I do this:

Code:
sh genderExtract.sh listofpeeps.csv

EDIT: I'm just doing this to get the gist of using -F and I don't want to do it through command line. I don't need to make a program to extract genders...but I could see that being useful for surveying purposes.
