(I'm talking about the shell Fish, esp. Fish's Fish.)

For Bash/ZSH, I had ~/.profile with some exports, aliases and other stuff.

I don't want to have a separate config for environment variables for Fish, I want to re-use my ~/.profile. How?

In The FAQ, it is stated that I can at least import those via /usr/local/share/fish/tools/import_bash_settings.py, however I don't really like running that for each Fish-instance.

You can use Bash to parse /etc/profile and ~/.profile, and then start fish.

1. 
   

   Create /usr/local/bin/fishlogin with contents

   
   
   

   #!/bin/bash -l
   
   exec -l fish "$@"
   
   

   
   


2. 
   

   Make it executable

   
   
   

   sudo chmod +x /usr/local/bin/fishlogin
   
   

   
   


3. 
   

   Add it to /etc/shells

   
   
   

   echo /usr/local/bin/fishlogin | sudo tee -a /etc/shells
   
   

   
   


4. 
   

   Set it as your default shell

   
   
   

   sudo usermod -s /usr/local/bin/fishlogin $USER
   
   

   
   

My current solution (see here for a maybe more recent version):

egrep "^export " ~/.profile | while read e

    set var (echo $e | sed -E "s/^export ([A-Z_]+)=(.*)$/1/")

    set value (echo $e | sed -E "s/^export ([A-Z_]+)=(.*)$/2/")



    # remove surrounding quotes if existing

    set value (echo $value | sed -E "s/^"(.*)"$/1/")



    if test $var = "PATH"

        # replace ":" by spaces. this is how PATH looks for Fish

        set value (echo $value | sed -E "s/:/ /g")



        # use eval because we need to expand the value

        eval set -xg $var $value



        continue

    end



    # evaluate variables. we can use eval because we most likely just used "$var"

    set value (eval echo $value)



    set -xg $var $value

end

For a much cleaner solution, you can use the foreign env plugin:

fenv source ~/.profile

I tried sourcing .profile on fish startup and it worked like a charm for me.

just do :

echo 'source ~/.profile;clear;' >  ~/.config/fish/config.fish

Restart terminal or iterm2, test an alias from .profile to test.

Note : Won't work with more complex .profile files that use syntax not available in fish - credit @erb

Install dash and add this line to your config.fish:

env -i HOME=$HOME dash -l -c 'export -p' | sed -e "/PATH/s/'//g;/PATH/s/:/ /g;s/=/ /;s/^export/set -x/" | source

You can't. fish's syntax is too different from Bourne shell (/bin/sh) syntax. This is the same reason you can't use .profile with other non-Bourne-derived shells, such as csh and tcsh.
