I'm trying to restart
mariaDBon Ubuntu but it's not letting me.

How to tag and store files, by metadata, in Python?
I want to build a manual file tagging system like this. Given that a folder contains these files:
data/ budget.xls world_building_budget.txt a.txt b.exe hello_world.dat world_builder.spec
I want to write a tagging system where executing
py -3 tag_tool.py -filter=world -tag="World-Building Tool"
These files were tagged with "World-Building Tool": data/world_building_budget.txt hello_world.dat world_builder.spec
Another example. If I execute:
py -3 tag_tool.py -filter="\.txt" -add_tag="Human Readable"
It will output
These files were tagged with "Human Readable": data/world_building_budget.txt a.txt
I am not asking "Do my homework for me". I want to know what approach I can take to build something this? What data structure should I use? How should I tag contents in a directory?

Appending values to existing values of environment variables in go
How can I append another value to an existing value of a go environment variable?
If CGO_CXXFLAGS has the value "-I/blah/blah"
Since the following doesn't work
$ go env -w CGO_CXXFLAGS="$CGO_CXXFLAGS -I/foo/bar"
I want to find a proper way to CGO_CXXFLAGS have the value "-I/blah/blah -I/foo/bar"
by avoiding to simply re-set all the values plus the new one, such as in:
$ go env -w CGO_CXXFLAGS="-I/blah/blah -I/foo/bar"
Update global variable from while loop
Having trouble updating my global variable in this shell script. I have read that the variables inside the loops run on a sub shell. Can someone clarify how this works and what steps I should take.

How do you use mktemp to create directory in Makefile?
Solved by awesome answer below. Expand the variables using := instead of =
mktemp: TEST:=$(shell mktemp -d) mktemp: echo $(TEST) touch $(TEST)/test.txt ls $(TEST) cat $(TEST)/test.txt rm -rf $(TEST)
This is a Makefile piece of code of how someone may use mktemp in a Makefile
TEST=$(shell mktemp -d) mktemp: echo $(TEST) touch $(TEST)/test.txt ls $(TEST) cat $(TEST)/test.txt rm -rf $(TEST)
This is an example output
❯ make mktemp echo /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.tQI5EeyW /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.tQI5EeyW touch /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.lVL3N8Rp/test.txt ls /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.sBW9FzgD cat /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.Ti53SWSw/test.txt cat: /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.Ti53SWSw/test.txt: No such file or directory make: *** [mktemp] Error 1
The expectation is that
cat /var/folders/62/wkysd_4n0w57ljl9ycfsd9cc0000gn/T/tmp.Ti53SWSw/test.txtwould not error.
How can mktemp be used in this case?

sudo amplify upgrade, which upgraded successfully amplify.
Now I can't use

If I use the
amplifycommand with no sudo nothing happens, not even a command not found...just pure nothing. Please help me, it's driving me insane.
