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.

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
