`printf -v foo ""` does not set foo=
|
| |
simple test code:
unset foo
printf -v foo ""
echo ${foo+set}

Hello,
Clearing out the remainder of my "maybe bugs" file, in no particular order.
1. Arithmetic assignment precedence / associativity.
Most shells (and GCC) consider not grouping the assignment in a situation like
this an error. Bash tolerates it, apparently reversing associativity:
: $((1 == x = 1)) # Error in dash/ksh/mksh/zsh/etc... more »

The trace looks aprolike this:

currently doable? Indirect notation used w/a hash
|
| |
I was wondering if I was missing some syntax somewhere...
but I wanted to be able to pass the name of a hash in
and store stuff in it and later retrieve it... but it
looks like it's only possible with an eval or such?
Would be nice....(??)*sigh*

part of the script, first do some sort of check to tell if the script has... more »
