When working on many feature branches, they tend to accumulate in the local Git clone. Even if they get deleted in upstream shared repos, they need to be cleared locally, too, otherwise they will stick around forever.
Here’s a quick one-liner to clean up every branch that is fully merged to main. It does make sure not to delete main and develop, though.
git branch -d $(git branch --merged main | grep -vE '(^\*|master|main|develop)')
As idle musing, and a way to show off my mastery of shell pipelines, I was wondering what my most-used shell commands are. It’s an easy few commands to pipe.
history | sed 's/^ *//;s/ \+/ /g' | cut -d' ' -f 2 | sort | uniq -c | sort -n | tail -n 20The outcome is rather expected. I feel validated (by my shell) in my own self-perception!

It’s always a bit confusing to reason about which startup files bash(1) is going to run in a given situation. It is documented, but the logic is not trivial.
So I made a chart (using PlantUML!). You’re welcome.
EDIT: There is also one for zsh(1) (PlantUML).
The main takeaway from this exercise is:

shmode,bashandzshdo slightly different things.
I finally mastered the shell (beit bash or zsh, but really, this is readline)’s history with command replacement. It took me 19 years and my entire family fortune to gather enough wits to read that part of the manual with enough attention and will as to learn to use it.
Essentially, you can recall previous commands from the history with !number. You can then change some content of the previous command programmatically before running it by adding :s/PATTERN/REPLACEMENT/ or :gs/PATTERN/REPLACEMENT/ (the first one will replace the first occurrence, the second one will replace them all).
