rename --expr "s/'//g;y/-/_/" --force --nometa --nows --lower-case --expr "s/_\./\./" maps/*/*.{pmp,xml}
# s/'//g: remove single quotes "at_world's_end.xml" => "at_worlds_end.xml"
# y/-/_/: replace hyphens with an underscore
# --force: needed for files where the only change is lowercase "Alpine_stef.xml" => "alpine_stef.xml"
# --nometa: replace shell meta-character with underscore, e.g. Pipe (|), Ampersand (&), Semicolon (;), ...
# --nows: replace whitespace with underscore
# --lower-case: :)
# s/_\./\./: remove underscores before the file name ends "temple_4_.xml" => "temple_4.xml"
# maps/*/*.{pmp,xml}: apply it to all files that fit the glob (some files could have "DELETED" at the end)
