comment Locked out of Ubuntu machine
"Connection refused" most likely means there isn't anything listening on that port. The SSH server might not have been started, might be misconfigured, or might be listening on a different port. I'm confused though; are you saying the issue occured when you installed OpenSSH?

Your programs might be configured to only listen for local connections, have you checked for this? Possibly related question: Cannot connect to postgres from remote host

If you're interested in viewing the output or any errors in the script, this question might be helpful too: How can I make a script that opens terminal windows and executes commands in them?

comment Find and remove many files by specific content
consider if you really need to search dir.*/*, maybe just . would be appropriate? find will (by default) act recursively

comment What is the definition of a regular expression?
I don't know if there is a single definition for "regular expressions" as the term is commonly used. There are different syntax specifications, such as POSIX regular expressions or Perl regular expressions, which include other "features" such as backreferences or lookaheads. These may no longer be regular expressions in the strictest sense (in the context of regular formal languages) but are still referred to as such.
