-n switch keeps empty columns

If your distribution does not ship with a recent column version that supports -n you can use this alternative:

perl -pe 's/(^|;);/$1 ;/g' file.csv | column -ts\; | less -S

Change the delimiter to your liking.

cat /etc/passwd | column -nts:

What others think

Useless use of cat.
