Zsh over-substituting aliases

In Bash, running tmux ls works properly. However, in Zsh, I get this error:

tmux: unknown option -- p
usage: list-sessions [-F format]

I suspect this is because Zsh is replacing ls of the command with my custom alias for ls:

alias -g ls='ls -p --color'

I tried setting alias -g tmux\ ls='tmux list-sessions', but that didn't work.

Is there any way to change Zsh's alias expansion/substitution behavior?

Solution

  • You are defining ls as a global alias, meaning it is expanded anywhere the shell sees ls, not just when it is used as a command. Just drop the -g option:

    alias ls='ls -p --color'
