If you only want one system that works for you, you may not really want to consider Unix if you already have a working Windows installation. I tried to persuade a friend of mine whom I know are quite proficient in computers to try Linux. Nope, he didn't dare to move.

To learn or not to learn depends totally on whether you have interests in it, because it is so much different compared with Windows. Of course, in my opinion you won't lose anything if you have a unix installation alongside your Windows installation, provided you have disk space. You can delete it if you don't like it, so I think it's good at least you have some tastes of what it is about.

Unix is not entirely open source, but most software on it are. Linux in particular is. Usually on x86 machines you install either *BSD or Linux. I think Linux is generally easier to set up (with installers) and gives you a more complete installation by default as shipped so you don't need to do a lot of post-install configuration. You can get more advice by doing a forum search here.

column

COLUMN(1)							   User Commands							 COLUMN(1)

NAME

       column - columnate lists

SYNOPSIS

       column [options] file...

DESCRIPTION

       The column utility formats its input into multiple columns.  Rows are filled before columns.  Input is taken from file or, by default, from
       standard input.	Empty lines are ignored.

OPTIONS

       -c, --columns width
	      Output is formatted to a width specified as number of characters.

       -t, --table
	      Determine the number of columns the input contains and create a table.  Columns are delimited with whitespace, by default,  or  with
	      the characters supplied using the separator. Table output is useful for pretty-printing.

       -s, --separator separators
	      Specify possible table delimiters (default is whitespace).

       -o, --output-separator separators
	      Specify table output delimiter (default is two whitespaces).

       -x, --fillrows
	      Fill columns before filling rows.

       -h, --help
	      Print help and exit.

ENVIRONMENT

       The environment variable COLUMNS is used to determine the size of the screen if no other information is available.

EXAMPLES

       sed 's/#.*//' /etc/fstab | column -t

BUGS

       The util-linux version 2.23 changed -s option to be non-greedy, for example:

       $ printf "a:b:c
1::3
" | column  -t -s ':'

       old output:
       a  b  c
       1  3

       new output (since util-linux 2.23)
       a  b  c
       1     3

SEE ALSO

       colrm(1), ls(1), paste(1), sort(1)

HISTORY

       The column command appeared in 4.3BSD-Reno.

AVAILABILITY

       The column command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
