How can I do this kind of thing in the Bourne shell? Below, I want to have a
list of sites, each with a list of 4 parameters. Then I want to have an
outer loop of sites with inner loop of parmeters per site.
Thanks so much for any help or advice.

In Bourne shell? Use another script language. For example, Perl, Tcl,
awk, etc.

Quote:> # site list
> site="acme baker charles"
> # 4 parameters for each site
> acme="ac01 ac02 ac04 ac04"

try
ps="echo $"$s
for parm in `eval $ps`
instead of

Quote:> for parm in "$s"
> do
> echo " $parm"
> done
> echo "---end of site parms---"
> done

Basic technique, construct a string containing the command, then
evaluate this string as a command.

It is not clear for me what you really want, so I just give you a few
variations (just typed, might have syntax errors):

data="acme ac01 ac02 ac04 ac04
baker bk01 bk02 bk03 bk04
charles ch01 ch02 ch03 ch04"

echo "$data" | while read s p1 p2 p3 p4 ; do
echo $s
echo $p1
echo $p2
echo $p3
echo $p4
done

#######

site="acme baker charles"
acmeParam="ac01 ac02 ac04 ac04"
bakerParam="bk01 bk02 bk03 bk04"
charlesParam="ch01 ch02 ch03 ch04"

for s in $site ; do
echo $s
eval param=\"\$${s}Param\"
for p in $param ; do
echo $p
done
done

#######

data="acme ac01 ac02 ac04 ac04 -- baker bk01 bk02 bk03 bk04 -- charles ch01 ch02 ch03 ch04 --"

set -- $data
while [ $# -gt 0 ] ; do
s=$1
shift
while [ $1 != "--" ] ; do
print $1
shift
done
shift
done

Creat a text file containing the data (you will use this to direct the data
into the script - for an example:

acme ac01 ac02 ac04 ac04
charles ch01 ch02 ch03 ch04
baker bk01 bk02 bk03 bk04
charles ch01 ch02 ch03 ch04
EOF
------------------------------------------------------
Then invoke the script by:

Quote:>>$sh script_name.sh < data_file_name.txt

-------------------------------------------------------
#!/bin/sh
while read $list p1 p2 p3 p4 p5
do
echo $p1
echo $p2
echo $p3
echo $p4
echo $p5
echo $p1 $p2 $p3 $p4 $p5
done

Hi,
try the following modification.

How about something like this (in portable bourne shell,
ksh-ers would have some optimizations, and the loop index
should be handled mathmatically - using expr if nothing
else):

site0="acme ac01 ac02 ac04 ac04"
site1="baker bk01 bk02 bk03 bk04"
site2="charles ch01 ch02 ch03 ch04"

for Ix in 0 1 2 3 4 5 6 7 8 9 10
do
eval siteParam=\"\${site}$Ix\"
if [ -n "$siteParam" ] ; then
set -- $siteParam
echo "$1"
while [ $# -gt 1 ] ; do
shift
echo " $1"
done
else
break;
fi
done

Obviously, that's limited to 11 sites, but you get
the idea. -Wm

Thanks so much to all. Some great and amazing approaches here, from very
simple to fuller features. I'll probably use a simple eval method now, but
may go to variable-length-check-for empty-string-to-terminate method later.

Here ya go =)

#!/bin/sh
site="acme:ac01;ac02;ac04;ac04 baker:bk01;bk02;bk03;bk04
charles:ch01;ch02;ch03;ch04"
for s in $site
do
sname=`echo $s | cut -d ":" -f 1`
sfield=`echo $s | cut -d ":" -f 2`
echo "Site name is $sname"

OLDIFS=$IFS
IFS=";"
for parm in $sfield
do
echo " $parm"
done
IFS=$OLDIFS
echo "---end of site parms---"
done
