Can someone help me with this in KSH and tell me why the exit status is
not returned?

Why is "haha" printed?

#!/bin/ksh

getNoGlobalProc()
{
local a=`ls sdfafa`

if [[ $? -ne 0 ]]; then
echo "$SCRIPTNAME : $LINENO : Could not obtain global number of
processes running"
return 1
fi

echo "haha"

return 0
}

getNoGlobalProc

Follow up 'sdfafa' doesn't exist I used it as an example of a garbage
program.

Is there a way to make the variable local in KSH and also have the exit
status of the command substitution returned?

context.]
