HI All,
I am having a bit of trouble using the find command in my shell (korn) script.
I was hoping someone could help me.

I am trying to build up a dynamic find command based on some parameters.

When I execute the command I get the following error:
find: incomplete statement

I have attached a stripped down version of the code which has the problem.

Any help would be apprecieated.
Thanks

if [ -n "$opt_file" ]
then
cat_str='\| nice -n 15 cat > '${opt_file}
else
cat_str='\| more'
fi

if [ -n "$opt_operator" ]
then
grep_str='\|nice -n 15 grep '${grep_str}

fi

if [ "$opt_enddate" -eq "$opt_startdate" ]
then
theExecStr="nice -n 15 find . -name \*.gz -exec nice -n 15 gunzip -c {} \; ${grep_str}${cat_str}"

$theExecStr
fi
