In bash, I can do
EDITOR=vim crontab -e. Can I get similar effect in Fish shell?
That is from the Documentation
SOME_VAR=1 command produces an error: Unknown command "SOME_VAR=1".
Use the env command.
env SOME_VAR=1 command
You can also declare a local variable in a block and that would not bypass the shell
begin set -lx SOME_VAR 1 command end
depending on a definition of
be function, this can fail
begin set -lx RAILS_ENV staging be rails r "p ENV['RAILS_ENV']" end
In order for it to work:
function be --description 'Runs bundle exec' --no-scope-shadowing bundle exec $argv end
Please, see the explanation of --no-scope-shadowing option
-S or --no-scope-shadowing allows the function to access the variables of calling functions. Normally, any variables inside the function that have the same name as variables from the calling function are "shadowed", and their contents is independent of the calling function.
