HPUX KSH for loop issues.
Wrote a KSH script on a RHEL server and moved it over to the HPUX server and it is not liking a loop that I put together. Here is the simple form of it that does not work in KSH:


Code:
for x in {0..$VARIABLE_NAME}
do
     echo $x
done

This works:


Code:
for x in {0..10}
do 

     echo $x 

done

I tried listing in the variable as "${VARIABLE_NAME}, but that did not work. I also tried "()" parenthesis and brackets "[]" but no luck. Any ideas? Again this works just fine on RedHat Linux. It does like the usage of a variable in the in span.

It's just this ksh version can't do it. Use:
Code:
for x in `seq 0 $VARIABLE_NAME`
do
  echo $x
done

By default on HPUX you won't find seq tool.

You can use while instead of for tho :
Code:
VAR=5
x=0
while [ $x -lt $VAR ]; do
x=$(( x + 1 ))
echo $x
done

Listing in variable works but the syntax you used is bash not ksh (strict form)...The same in ksh your should not use:
Code:
A=`who am i -R`    
#Though it still works...
#but
A=$(who am i -R)

So:
Code:
for i in ${ls a*}; do echo $i; done
ksh: ${ls a*}: bad substitution
ant:/home/vbe/test $ for i in $(ls a*); do echo $i; done
a000
a001
a002
a003
a004
ant:/home/vbe/test $ uname
HP-UX
ant:/home/vbe/test $
