Getting Sum, Count and Distinct Count of a file
Hi all this is a UNIX question.
I have a large flat file with millions of records. col1|col2|col3 1|a|b 2|c|d 3|e|f 3|g|h footer**** I am supposed to calculate the sum of col1 1+2+3+3=9, count of col1 1,2,3,3=4, and distinct count of col1 1,2,3=c3 I would like it if you avoid external commands like AWK. Also, can we do the same by creating a function? Please bear in mind that the file is huge Thanks in advance Last edited by Franklin52; 02-28-2009 at 06:08 AM.. Reason: urls removed |
