I have been using the sort command for years with a syntax as follows: cat $file | sort -t, +1
I create filesystems on Linux and AIX from a CSV file and sort by the second column as shown above. Recently I have tried this command on RHEL 5.1 and it fails. So I went and tried on Ubuntu 9.04 and also fails. Is this a bug or has the syntax for this type of sorting by columns changed? ubuntu 9.04 and RHEL 5.1 command: cat a.csv 1,3,3,4 1,9,3,4 1,2,3,4 $ cat a.csv | sort -t, +1 sort: open failed: +1: No such file or directory RHEL 4: # cat a.csv 1,3,3,4 1,9,3,4 1,2,3,4 # cat a.csv | sort -t, +1 1,2,3,4 1,3,3,4 1,9,3,4 # cat /etc/redhat-release Red Hat Enterprise Linux ES release 4 (Nahant Update 5) Thanks for any help you can provide.
