We can also combine by positively matching:
irb(main):001:0> s = "#hit#here#"
=> "#hit#here#"
irb(main):002:0> s = s[/^#?(.*?)#?\z/, 1]
=> "hit#here"
All possible combinations
irb(main):003:0> %w{hi#there #hi#there hi#there# #hi#there#}.each {|s|
p s[/^#?(.*?)#?\z/, 1]}
"hi#there"
"hi#there"
"hi#there"
"hi#there"
=> ["hi#there", "#hi#there", "hi#there#", "#hi#there#"]
Kind regards
