here is a example for str+str=command,

###script 1###
str1='ls'
str2='-l'
str3="$str1 $str2" #notice the formular
$str3

###script 2###
if debugout=true ; then
str1=' '
else
str1='#'
fi
str2='echo this is debug output'
str3="$str1 $str2"
$str3

but actually, when str1=#, I got following err "# is not recognized"

who have any idea ,pls share with me. THanks vivi[/quote]

I think you need something as follows:

Code:

debug="0" # 0 - true, nonzero = false
str1='ls'
str2='-l'
str3="$str1 $str2" #notice the formular
&#91; "$debug" == "0" &#93; && echo "$str1 $str2 $str3" || $str3

if debug is zero then display the values of all three variables str1,str2,str3 else execute command
