GNU bash, version 5.2.37(1)-release (x86_64-pc-linux-gnu)
OS: Gentoo Linux
Originally met this while the download of iso file in firefox was
nearing completion, and I was preparing myself to move the
downloaded foobar.iso file elsewhere. I opened terminal with bash,
typed "mv foobar." in the Downloads dir and pressed <tab>. Two options
appeared: foobar.iso and and foobar.[somecode].iso.part. I kept pressing
<tab>, but after the download finished, with repeated presses bash kept
displaying "foobar.iso" as a single option of completion and did not
complete to the already singular name.
Steps to reproduce:
1) in one instance of bash, run
touch foobar.a; touch foobar.b; sleep 10; rm foobar.b
2) run second instance concurrently, type "ls foobar.",
press <tab> twice to get the two options existing at that moment
("foobar.a" and "foobar.b")
3) keep pressing <tab> repeatedly
4) as the 10 seconds pass and the situation becomes clear and
complete-able, "foobar.a" is never completed to with repeated
presses of <tab>, it is (strangely) only displayed as a single
option for completion.
The result on screen around the 10th second looks as follows:
# ls foobar.
foobar.a foobar.b
# ls foobar.
foobar.a foobar.b
# ls foobar.
foobar.a
# ls foobar.
foobar.a
# ls foobar.
foobar.a
Expected behaviour:
Bash should complete to "foobar.a" as soon as it is an unique option,
i.e. as soon as foobar.b is removed after 10 seconds. Offering a
singular option for completion does not make sense anyway.
Additional note:
Also, when, in the erroneous situation after the 10 seconds elapsed, the
"." at the end of filename is deleted and written again (visually the
same situation) and then <tab> is pressed, the completion succeeds.
