>Description:
When using some of the built-in commands with sh or ksh the
variable won't reset back. I've found that it happens with
':' and internal functions at least.
>How-To-Repeat:
iku@kameli:/tmp% cat /tmp/test3
random_function()
{
}
a=foo
a=temp ls >/dev/null
echo "$a"
# : is a built-in
a=temp :
echo "$a"
a=tempvalue random_function
echo "$a"
iku@kameli:/tmp% sh /tmp/test3
foo
temp
tempvalue
iku@kameli:/tmp% ksh /tmp/test3
foo
temp
tempvalue
