Is there a naming convention for new bash commands?

When creating a new Bash command that has multiple words, such as remove-unused-scripts, is there a common naming convention? For instance, should it be remove-unused-scripts, or remove_unused_script, or removeUnusedScripts, or something else entirely?

I'm fairly new to Bash, just want to make sure I don't form any bad habits early on.

Thank you for your time.

https://google.github.io/styleguide/shell.xml#Naming_Conventions suggests to use lowercase and some underscores. You can read the complete guide for more reasonable conventions, including examples.

I think most languages recommend remove_unused_script over removeUnusedScript these days for readability. remove-unused-scripts is a legal file name for a script. bash allows function names to contain hyphens:

some-func () {
    echo hi
}

but that isn't portable; POSIX function names are restricted to letters, numbers, and _.
