I want to create an alias for
cd - which should be just a dash (
I tried without success:
alias -='cd -' # bash: alias: -=: Invalid option alias \-='cd -' # bash: alias: -=: Invalid option alias '-'='cd -' # bash: alias: -=: Invalid option alias '\-'='cd -' # bash: alias: `\-': Invalid alias name.
The former three are the same (only different input, but bash turns all of them into the same command
alias with a single argument
-=cd -), so it's no surprise the error message is the same. I'd guess that if the argument starts with a dash, it's parsed as a flag rather than the alias name.
Is it even possible to use
- as an alias name?
