Ok, Don't have idea about template thing. but regarding your question,

you can do something like:

Code:
#!/bin/ksh
eval $(awk 'BEGIN { FS = ";"}
 
function _p (field,cnt)
{
 split(field,arr," ");
 for (n in arr)
 print "var_"cnt"_"n"="arr[n]
}
{ for(i=1;i<=11;i++){ print "var_"i"="$i }
  for(i=12;i<=17;i++){ if ($i != "") {_p($i,i)} else { print "var"i"="$i} }
}' filename) 

## shell part begins


echo $var_1
echo $var_2
echo $var_3
echo $var_4
echo $var_5
echo $var_6
echo $var_7
echo $var_8
echo $var_9
echo $var_10
echo $var_11
echo $var_12_2
echo $var_12_3
echo $var_12_1
echo $var_13_2
echo $var_13_3
echo $var_13_1
echo $var_14_2
echo $var_14_3
echo $var_14_1
echo $var15
echo $var_16_2
echo $var_16_3
echo $var_16_1
echo $var_17_2
echo $var_17_3
echo $var_17_1

Here, filename is the name of the file which contains that one line with 17 records separated by semicolon.

This will create the shell variables in the following manner:

Code:
for 1st field var_1
for 2nd field var_2
.....
so on


for multi field, the rule would be:

Code:
for 17 field, 1st value, var_17_1 
for 17 field, 2nd value, var_17_2
...
so on

ucblinks

ucblinks(1B)					     SunOS/BSD Compatibility Package Commands					      ucblinks(1B)

NAME

       ucblinks - adds /dev entries to give SunOS 4.x compatible names to SunOS 5.x devices

SYNOPSIS

       /usr/ucb/ucblinks [-e rulebase] [-r rootdir]

DESCRIPTION

       ucblinks  creates symbolic links under the /dev directory for devices whose SunOS 5.x names differ from their SunOS 4.x names. Where possi-
       ble, these symbolic links point to the device's SunOS 5.x name rather than to the actual /devices entry.

       ucblinks does not remove unneeded compatibility links; these must be removed by hand.

       ucblinks should be called each time the system is reconfiguration-booted, after any new SunOS 5.x links that are needed have been  created,
       since the reconfiguration may have resulted in more compatibility names being needed.

       In  releases prior to SunOS 5.4, ucblinks used a  nawk rule-base to construct the SunOS 4.x compatible names. ucblinks no longer uses  nawk
       for the default operation, although  nawk rule-bases can still be specifed with the -e option.  The  nawk rule-base equivalent to the SunOS
       5.4 default operation can be found in /usr/ucblib/ucblinks.awk.

OPTIONS

       -e rulebase     Specify rulebase as the file containing nawk(1) pattern-action statements.

       -r rootdir      Specify rootdir as the directory under which dev and devices will be found, rather than the standard root directory /.

FILES

       /usr/ucblib/ucblinks.awk        sample rule-base for compatibility links
