my #1 bash gripe is that newer versions do not
expand command lines containing '$' in emacs
readline editing mode. I used to be able to do:
$ export SRC=../somedir
$ less ${SRC}/
( meaning press horizontal tab key )
and emacs mode readline would expand,
displaying the contents of ../somedir .
Now
ed to give to enable it? Thanks!

with an integration with glibc "getenv()" to support this ?

Good day Chet, list -
I'm concerned about the difference in output of these functions with
the example input
given on the '$' prefixed line below (with 4.2.29(2)-release
(x86_64-unknown-linux-gnu)):
function count_args {v=($@); echo ${#v[@]}; }
function count_colo
uldn't it
be doing so?
Escaping works in filenames, so why not in word-splitting ?
Thanks & Regards,

Having defined a function _F to return a non-zero return status :
$ function _F () { return 255; }
I'd expect to be able to test this return status in an if clause - but
this is what happens:
$ if ! _F ; then echo '_F returned: '$?; fi
_F returned: 0
whereas if I just run F inline, the return

There seems to be no way of testing if an array variable is associative or not ,
yet attempting to make associative assigments to a normal array results in a
syntax error .
I have something like:
declare -xr TYPE_ARRAY=0 TYPE_ASSOC=1
function f()
{ declare -n an_arra
ciative array, as
declare -F does for functions ?
Or is there some way to test if a variable is an associative array or not?

Good day Chet, bash-list -
I just checked out the latest git head, applied the bash43-025 patch, and built
$ ./bash --version
GNU bash, version 4.3.25(3)-release (x86_64-unknown-linux-gnu)
...
which PASSED its 'make check' test suite, both under Ubuntu 14.04.1 LTS
and under RHEL-6.5+ , on an x

Sorry, my mistake - a nasty coincindence that it was the first
thing I tried with the new bash version.

Good day -
Please could anyone explain why the first command below produces no output:
$ ( declare -A a=([a]=1); if [ -v a ]; then echo yes; fi )
$ ( declare -a a=([0]=1); if [ -v a ]; then echo yes; fi )
yes

There does not appear to be any documentation about
different behaviour of -v for as
Thanks to all who replied.
I would really like -v to do as it documented to do :
" -v
True if the shell variable varname is set (has been assigned a value)
"
To me, the fact that -v does not return true if the variable is an array
and does not have element 0 - or element '0' in the case of asso

Can either of these new behaviors be disabled in bash 5.0.2 ?

I think this is a bug:

if [[ "$s" =~ ^some text:[\ $tab]+([0-9.]+) ]]; then
echo "${BASH_REMATCH[1]}";

Do you agree ?
If not,
With a build of bash 4.3 patchlevel 42
on a Linux x86_64 system I am getting
warning messages on stderr when
running a certain script like:
"wait_for: no record of process 8278" .
Running bash with the script as
input under strace shows that process 8277
does a successful wait4(-1,...) which DOE
emits the
message:
"xxx.sh: line 46: No record of process 8278" .
Line 46 in my script consist of
function f()
.
This seems buggy to me - I'll try developing a
patch to fix it and will post back here.

I think it should, as it is rather unfair of bash to make its
internal bookkeeping errors appear as if they could be
user programming errors.
