Is there an OR in linux commands?

Question

linux

When I enter the command
rm -rf file_1*
Is it possible to specify instead of just the number 1, for example 1 or 2, in regular expressions it would be (1|2) for example

Answer 1

Actually it depends on the shell. You probably have bash, so man bash has an EXPANSION section, specifically Pathname Expansion.
In this case file_[12]* should work
