I have been trying to use rpm or dnf to remove some rpms. Most
the ones I am concerned with are docker related, and or to do with go
(golang). You certainly can't use wildcards with rpm erase. I have a
list generated with the date these rpms were installed, but I am not
THAT good with CLI and bash operations like cut, xargs, sed and so on to
alter the list; and I wouldn't be sure how to pipe the list contents or
redirect to rpm the text's content from the ascii text file, to erase
these particular rpms. Is there a way to mass erase many files (with rpm
switches or such) using rpm? Here is an example of what I have been
trying to do, ex:
list.txt,
gcc-devel // example,
python-devel //example
rpm -e // would this list content be redirectable to rpm -e ?
cat list.txt
lists rpms,
rpm -e < cat list, or
cat list | rpm -e
do not work.

Write your list so that all the packages are on a single line, and just
add rpm -e to the head of that line:
rpm -e foo bar baz
Or:
for i in `cat list`; do rpm -e $i
I would honestly probably use yum for this, though, since it takes care
of dependencies and the like.
So if your list of packages is:
foo bar baz
I would just add "yum remove" to the beginning of the list:
yum -y remove foo bar baz

I see, thanks much Thomas, so this would then be kind of doing the
work of grep. I have used cat and grep together with a pipe, which seems
similar
cat list |grep "word"
And it seems to work.

It worked using this,
yum remove $(cat list)
I have never heard of 'command substitution'. seeing the $ has always
made me think of variables, like such,
echo $PATH, to see a value.
Cheers.

Be careful with a "-y" on a dnf/yum remove. I have seen yum/dnf determine
that a lot of packages need to go. The protected multi-lib/packages may
stop a total disaster, but you could also remove a lot of packages you
don't want to remove and have to go back through the list and reinstall a
lot.
I have seen people do the removes's without the -y and watch screen fulls
of packages scroll by and still answer 'y', and destroy a system
(pre-protected-multi-lib).
For a non-automated one-of remove the additional safety gained by having to
answer y after seeing that what it wants to remove is a small price to pay.

Even better: "dnf mark remove $(cat list)

Unmarks the specified packages as installed by user. Whenever
you as a user don't need a specific pack‐
age you can mark it for removal. The package stays installed
on the system but will be removed when
Autoremove Command or Remove Command along with
clean_requirements_on_remove configuration option set
to True is executed. You should use this operation instead of
Remove Command if you're not sure whether
the package is a requirement of other user installed packages
on the system.

You can do this with rpm as well, but it requires greater care.
Here is

cat list.txt

Indeed, rpm doesn't take the list of packages on stdin. You
can use a number of techniques here (we all develop our
favorite habits, but knowing "there is more than one way to
do it"™ is always handy.
Here's how I setup a test:
$ printf '%s\n' gcc-devel python-devel >/tmp/list
$ cat /tmp/list
gcc-devel
python-devel
You could use xargs:
$ xargs sudo dnf remove </tmp/list
This will display the 'dnf remove' output, showing you what
it would do. Then it will exit immediately because there is
no way for it to read the 'Is this ok [y/N]:' prompt. You
can run it again with the '-y' option.
Another way to feed the list to dnf (or rpm) is to use
command substitution:
$ sudo dnf remove $(cat /tmp/list)
Bash¹ has a shortcut for that cat usage which is slightly
faster:
$ sudo dnf remove $(< /tmp/list)
¹ Other shells likely have this is something similar, but
I'm not familiar with them offhand
A for loop works too, but that doesn't work very well when
there are interdependent packages in the list (particularly
with rpm, but even with dnf it can cause problems). It's
also a _lot_ slower to run the rpm or dnf command multiple
times instead of once.
That's just two ways to go about it. Hopefully they help.

I have always assumed that using rpm -e will mess up dnf.
so I never use rpm for any operation that modifies the system.
I think I shot off a foot a decade or so ago doing that.

I think I shot off a foot a decade or so ago doing that.
It won't mess up dnf. dnf uses the rpm database, so it will know that
the package isn't there. However, you won't have any history to track
that you made the change. And if you force a removal, then dnf will
likely be unhappy about missing dependencies at some point in the future.
