I can use it a little bit, but don't know how to make it do the above. Here's
the code for the list below:

clear
num=1
set  "/" "/bin" "/dev" "/etc" "/home" "/lib" "/proc" "/root" "/sbin" "/usr" 
"/var" ".." `/bin/ls -F`
for file in "$@" ; do
printf  "%s[${num}] $file   "
num=`expr $num + 1`
done

[1] /   [2] /bin   [3] /dev   [4] /etc   [5] /home   [6] /lib   [7] /proc   
[8] /root   [9] /sbin   [10] /usr   [11] /var   [12] ..   [13] cardmgr   [14] 
chat   [15] install-to-hd   [16] lsof   [17] nc@   [18] pppd   [19] 
pure-authd   [20] pure-ftpd   [21] pure-ftpwho   [22] pure-mrtginfo   [23] 
pure-quotacheck   [24] pure-uploadscript   [25] receive   [26] send   [27] 
tcpdump [28] special/

I know I can get the columns and rows of someone's screen with 'stty size', 
and divide the
number of files by 4 with 'expr NUM / 4'....

Do you know how to turn that mess into, say, 4 neat columns, with printf? I'd 
love to be able
to do that.

I have the manpage and a C reference for the other escapes. It's just that my 
Greek is a little
rusty :-\

Thanks,

Lee
