for loop

[byuen]

for a korn shell, what is the equivalent c++ command for:

(for int i = 0; i < 20; i++) ?

thanks,

Yes, but I do not think it is what you wish. Here is a good Korn shell overview site:

http://www.vis.ethz.ch/manuals/Unixkurs/ksh.html#looping

for foo in $(ls);do
if [[ -d $foo ]];then
print &quot;$foo is a directory&quot;
else
print &quot;$foo is not a directory&quot;
fi
done

But, if you need a counter then do this:
count=99
while [[ $count -gt 0 ]];do
print &quot;\$count is $count&quot;
(( count -= 1 ))
done

This works...

   #!/bin/ksh

   CTR=21  # Needs to be one more than the number of times you want

   while (( CTR -= 1 ))
   do
      print "Counter CTR is ${CTR}"
   done

Of course this starts at 20 and counts down, but it does give you a loop that executes just that many times.

Hope this helps.

ksh93 allows the use of (i=0; i < 10; i++) functionality.
