Create an alias - in Bash?

Question

How can I create an alias named - in Bash? None of the following works:

alias -='cd -'
alias \-='cd -'
alias '-'='cd -'

with error:

bash: alias: -=: invalid option
alias: usage: alias [-p] [name[=value] ... ]

Answer 1

Use the following:

alias -- -='cd -'

-- is often used (especially with Gnu programs) to stop parsing the following arguments as options. That's also how you can e.g. rm files whose names start with -.
