KDE Plasma 6.8, scheduled for mid-October, is already taking shape with a notable KWin performance change for NVIDIA users.

I’m trying to build a Bash script that processes a list of tasks in parallel with a fixed concurrency limit (e.g., 4 jobs at a time), but I also want it to behave robustly in real-world conditions.
Specifically, I want to:
Limit the number of concurrent background jobs using pure Bash (no GNU parallel).
Correctly capture and aggregate exit codes from all jobs.
Handle SIGINT/SIGTERM so that if the script is interrupted, it cleanly terminates all running child processes.
Avoid leaving orphaned or zombie processes.
I’ve experimented with wait -n, job control, and traps, but I’m running into edge cases where some processes don’t terminate properly or exit codes get lost.
What’s a solid pattern or structure in Bash to implement this kind of controlled parallel execution with proper signal handling and cleanup?
Hey r/fedora! 👋
A few months ago I shared a fish shell function to browse RPM installation history. It got a good reception and has evolved quite a bit since, so here's an updated post — and this time there's a bash version too for non-fish users.
What problem does it solve:
dnf history is powerful but noisy when you just want to know what was installed and when. I use this tool to get a quick, clean picture of recent system changes.
Practical example: my printer recently stopped working. rpm_installed yd showed me everything installed the day before — cups was in the list. That was enough to point me at the culprit without digging through logs.
On Fedora where updates are frequent and often come in batches, having a readable install timeline is genuinely useful.
Usage:
rpm_installed today
rpm_installed yesterday
rpm_installed days 7
rpm_installed since 2026-03-01
rpm_installed since 2026-03-01 until 2026-03-31
rpm_installed count per-day
rpm_installed count per-week
Short aliases: td, yd, lw, tm, lm
Output is grouped by date with per-day package counts, auto-pages on long output, and caches results for fast repeated calls.
Install (fish version) via Fisher:
fish
fisher install fdel-ux64/fish-rpm-installed
https://github.com/fdel-ux64/fish-rpm-installed
Install (bash version):
bash
curl -sL https://raw.githubusercontent.com/fdel-ux64/bash-rpm-installed/main/bin/rpm-installed \
-o ~/.local/bin/rpm-installed
chmod +x ~/.local/bin/rpm-installed
https://github.com/fdel-ux64/bash-rpm-installed
Both versions tested on Fedora 43, Fedora 44 and OpenSUSE Tumbleweed.
Bonus — kver: if you're also curious where your running kernel stands relative to upstream, there's a companion fish function in my fish-config repo:
kver # show current running kernel
kver -c # fetch latest stable from kernel.org and compare
# times out after 5s if kernel.org is unreachable
# offers to open kernel.org in your default browser
