Integer in conditional ksh statement
Hi,

This is confusing me and I would appreciate some help.

Consider this script

Code:
 
#!/bin/ksh
typset -i stat=`ls -l $WORK/stat |wc -l`
if (( $stat < 20 ))
then
echo true
else
echo false
fi

If the value of $stat is say 29. When I run this above it echos true and not false. How can this be, I know $stat is an integer as you can do the expr $stat + 1 and it increases.

This is really bugging me and I bet it is something really obvious

Sorry, but why don't you use:
Code:
-lt

Code:
#!/bin/ksh
typset -i stat=`ls -l $WORK/stat |wc -l`
if [ $stat -lt 20 ]
then
echo true
else
echo false
fi

I've tried everything

[ $stat -lt 20 ]
(( $stat<20))

when stat = 29 they all validate as true, does not make sense

I don't use typeset, try the following:

Code:
#!/bin/ksh
stat=`ls -1 $WORK/stat |wc -l`
if [ $stat -lt 20 ]
then
echo true
else
echo false
fi

Sorry, but what you are trying to validate? Maybe there are other ways to do what you want.

I took out the typeset and it just doesn't work, really weird. I was thinking if the command ls -l $WORK/stat |wc -l does not return an integer.

Anyway what I am trying to do is say....if the number of files is less than a threshold then do something else sleep x seconds and check again.

Maybe this helps you:

Code:
#!/bin/ksh
stat=`find ${WORK}/stat -maxdepth 1 -type f | wc -l`
if [ ${stat} -lt 20 ]
then
echo true
else
echo false
fi

Does your original code have typeset, or actually typset?

I can't get it to break (with typeset) on RHEL ksh93s+.
