where am i wrong?

Hi anbody know where i'm wrong in?

#!/bin/ksh
ID1=1234
ID2=2345
ID3=3456

count=1
while [ "$count" -lt "4" ]
do
if [ eval echo \$ID$count = "1234" ];then
echo yeah
else
echo wrong
fi
count=$((count + 1))
done

count=$(($count + 1))

...
if [ "$(eval echo \$ID$count)" = "1234" ];then
...

my count=$(($count + 1)) is correct...

this line is wrong... if [ eval echo \$ID$count = "1234" ];then

but if i use [ "$(eval echo \$ID$count)" = "1234" ] then the result will be ID1 which i want is ID1 value (1234)

you missed a "$" there as well

Not necessarily. Between $(( )) and (( )) variables are recognised with or without a $ prefix.

Oh, yes.

Sorry, I missed that out.

thank jlliagre it works... for if [ "$(eval echo \$ID$count)" = "1234" ];then
